Careers

In this new series, members of the SCI Mid-Career group offer advice on career management and how to overcome career challenges.

SCI Member David Freeman

In our latest interview, we hear from David Freeman, Research & Technology Director for Croda’s Energy Technologies business.

Please tell us about yourself and your career journey.
After a PhD in organic chemistry, I started my career with ICI Paints in Slough in 1998, working in a product development role. Within a couple of years, I moved to another ICI business, Uniqema, and had various technical roles around the chemical synthesis or process development of new materials.

These early roles – and the people I worked with during this time – had a big impact on me in terms of ways of working and how to deal with people. I subsequently joined Croda in 2006 and have since had further technical roles – initially around the technical management of Synthesis programmes in Croda, then technical management of Applications programmes, and finally on to my current role of R&T Director for Croda’s Energy Technologies business.

This last transition was probably the most interesting and challenging as it forced me to think much more strategically about the “what” rather than the “how” and what leadership versus management was all about. I see this area as being hugely important to the Mid-Career group.

What are your keys to managing your career at this stage?
Development remains really important to me from a personal perspective. I have always driven my own development, but been well supported by the organisations I’ve worked for: both by technical management teams and HR teams. At the mid-careers stage, there are lots of important things to think about but I consider the following to be key:

  • (i) Self-understanding and feedback: make sure you understand your strengths and weaknesses and how these manifest themselves with colleagues by seeking open and honest feedback
  • (ii) Get external perspectives on your areas of interest and expertise. This for me is really key in challenging thinking and bringing new ways of working and innovation to your role
  • (iii) Understand the big picture: make sure you’re clear about what’s going on in the world at a high level and the part you and your organisation have to play in meeting these challenges.

What challenges are there around mid-career support?
I feel very fortunate to have worked for organisations where development is extremely important – support is always on hand when I need it. The key challenge is a personal one and it’s about making enough time to focus on the right development areas. We are all busy but if we want to develop ourselves enough, then we will find that time!

When you live in a cold country, you think of hot days as a blessing. Air conditioning units are for those in far-away places – humid countries where the baked earth smell rises to meet you when you step off the plane.

But cooling comes at a cost. According to the UN Environment Programme, it accounts for 7% of global greenhouse gas emissions. Some of us are visual learners; so, the sheer cost of cooling really hit me when I stared up at an apartment building in Hong Kong with hundreds of air conditioning units perched above the windows like birds.

And it isn’t just the Hong Kongers feeling the heat. The cooling industry as a whole is under pressure to cut its greenhouse gas emissions. The International Energy Agency expects emissions from cooling to double by 2030 due to heat waves, population growth, urbanisation, and the growing middle class. By 2050, it forecasts that space cooling will consume as much electricity as China and India do today.

Air conditioning units cling to a building

All of this was captured by the Cooling Suppliers: Who's Winning the Race to Net Zero report released by the Race to Zero campaign, the Kigali Cooling Efficiency Program (K-CEP), Carbon Trust and other partners in the UN Environment Programme-hosted Cool Coalition.

This report's authors found that only five of the 54 cooling companies they assessed have committed to net-zero targets. The document outlines three areas that must be addressed on the Cooling Climate Pathway: super-efficient appliances, ultra-low global warming refrigerants, and the widespread adoption of passive cooling measures such as clever home design and urban planning.

So, while builders adjust window sizes, introduce trees for shading, and choose materials (such as terracotta cooling systems) thoughtfully to temper the sun’s gaze, others are availing of different methods.

For example, the COP26 (the 2021 UN Climate Change Conference) Champions Team has just released its Net Zero Cooling Action Plan that includes a Cool Calculator tool to help companies and governments run simple calculations to see where they could decarbonise their cooling systems. Similarly, the UK's Environmental Investigation Agency (EIA) has launched a net-zero cooling product guide that showcases energy-efficient products run on natural refrigerants.

SCIblog 1 April 2021 - The Cool Coalition feels the heat - image of building green walls

Green walls are one of many passive cooling approaches used to reduce our reliance on mechanical systems.

However, it’s clear that the softly-softly approach won’t suffice. The EIA has called on governments to do more to encourage organisations to adopt sustainable cooling, to make concrete policy commitments, and speed-up the phase-out of climate-warming refrigerants such as hydrofluorocarbons.

“The development and expansion of net-zero cooling is a critical part of our Race to Zero emissions,” said Nigel Topping, UK High Level Champion for COP26. “In addition to technological breakthroughs and ambitious legislation, we also need sustainable consumer purchasing to help deliver wholesale systems change.”

We all love the technological panacea – innovations that will cure all the climate ills we have inflicted on the world. But the solution will also involve stodgy government regulations and changing consumer habits, and a reliance on the continued fall in renewable power generation.

For those in traditionally cooler climes, it’s no longer someone else’s problem. It was a balmy 22°C in London this week and we’re not even in April yet. So, it’s certainly time to turn up the heat on the cooling industry.

What do grape stalks, pineapple leaves, corn cobs, rice husks, sheep’s wool, and straw have in common? Apart from being natural materials, they have all been used to insulate homes. Increasingly, people are turning towards natural, sustainable materials as climate change and waste have become bigger problems.

Existing building insulation materials such as synthetic rock wool are excellent at keeping our homes warm in winter, but the conversation has moved beyond thermal performance. Energy use, re-usability, toxicity, and material disposal are all live considerations now, especially with regulations and emissions targets tightening. So, rock wool might perform better than straw bale insulation but straw is biodegradable, reusable, easy to disassemble, and doesn’t require large amounts of energy to process.

Sheep’s wool and hemp insulation have also become attractive to homeowners and housebuilders alike, but an even more encouraging prospect is the use of waste materials to create next generation insulation. In this spirit, researchers at Flinders University in Adelaide, Australia, have taken waste cooking oil, wool offcuts, and sulphur to process a novel housing insulation material.

SCIblog 18 March 2021 - image of recycled paper

Recycled paper is one of many waste materials that has found its way into domestic insulation.

To make this composite, they followed several stages. In the first stage of the synthesis, the researchers used inverse vulcanisation to create a polysulphide polymer from canola oil triglyceride and sulphur. They then mixed this powdered polymer with wool and coated the fibres through electrostatic attraction. This mixture was compressed through mild heating to provoke S−S metathesis in the polymer and bind the wool. The wool bolsters the tensile strength of the material, makes it less flammable, and provides excellent insulation. The result is a sustainable building material that fulfils its function without damaging the environment.

For Associate Professor Justin Chalker, the lead author of this study, this work provides an ideal jumping-off point. “The promising mechanical and insulation properties of this composite bodes well for further exploration in energy saving insulation in our built environment,” he said.

Sustainable transformation

It is clear that ventures like the one in Adelaide will continue to sprout all over the world. After all, necessity dictates that we change the way we build our homes and treat materials.

A recent report from Emergen Research predicts that the global insulation materials market will be worth US $82.96 billion (£59.78 billion) by 2027. The same report was also at pains to mention that the increasing demand for reduced energy consumption in buildings will be a significant factor in influencing industry growth.

“Market revenue growth is high and expected to incline rapidly going ahead due to rising demand for insulation materials... to reduce energy consumption in buildings,” it said. One of the main reasons given for this increased green building demand was stricter environmental regulations.

And Emergen isn’t the only organisation feeling the ground moving. Online roofing merchant Roofing Megastore, which sells more than 30,000 roofing materials, has detected a shift towards environmentally friendly materials, with many homeowners sourcing these products themselves.

SCIblog 18 March 2021 - image of a rock wool insulation panel

Rock wool insulation panels have come under greater scrutiny in recent times.

Having analysed two years of Google search data on sustainable building materials, the company found that synthetic roof tiles are generating the most interest from the public. Like the Flinders insulation, these roof tiles make use of waste materials, in this case recycled limestone and plastic. And you don’t need to look far down the list to find sustainable insulation materials, with sheep’s wool insulation in 9th place, wood fibre insulation in 10th, and hemp insulation in 12th.

Over time, the logic of the progression towards natural, less energy-intensive building materials will become harder to ignore. “Traditional materials such as synthetic glass mineral wool offer high levels of performance but require large amounts of energy to produce and must be handled with care while wearing PPE,” the company noted. “Natural materials such as hemp or sheep’s wool, however, require very little energy to create and can be installed easily without equipment.”

So, the next time you look down at your nutshells, spent cooking oil, or tattered woollen sweater, think of their potential. In a few years, these materials could be sandwiched between your walls, keeping you warm all winter.

Energy

A completely clean, renewable energy system that can be produced locally and that can easily power heat, energy storage and transportation, and travel — that's the future that promoters of a hydrogen economy envisage.

If it sounds a bit like rocket science, that's because it is. Hydrogen is what's used to fuel rockets — that’s how powerful it is. In fact, it’s three times more powerful as a fuel than gas or other fossil-based sources. And, after use, it’s frequently converted to drinking water for astronauts.

US President Joe Biden has highlighted the potential of hydrogen in his ambitious plans for economic and climate recovery and a number of recent reports have been encouraging about hydrogen’s breakthrough moment, including McKinsey and Company (Road Map to a US Hydrogen Economy, 2020) and the International Energy Agency.

SCIblog - 11 March 2021 - Hydrogen Economy - image of a Hydrogen fuel cell

Hydrogen fuel cells provide a tantalising glimpse into our low-carbon future

The McKinsey report claims that, by 2030, the hydrogen sector could generate 700,000 jobs and $140bn in revenue, growing to 3.4 million jobs and $750bn by 2050. It also believes it could account for a 16% reduction in CO2 emissions, a 36% reduction in NOx emissions, and supply 14% of US energy demand.

So how does it work?

Simply put, hydrogen fuel cells combine hydrogen and oxygen atoms to produce electricity. The hydrogen reacts with oxygen across an electrochemical cell and produces electricity, water, and heat.

This is what gets supporters so excited. In theory, hydrogen is a limitless, incredibly powerful fuel source with no direct emissions of pollutants or greenhouse gases.

So what's the problem?

Right now, there are actually a few problems. The process relies on electrolysis and steam reforming, which are extremely expensive. The IEA estimates that to produce all of today’s dedicated hydrogen output from electricity would require 3,600TWh, more than the total annual electricity generation of the European Union.

Moreover, almost 95% of hydrogen currently is produced using fossil fuels such as methane, natural gas, or coal (this is called "grey hydrogen"). Its production is responsible for annual CO2 emissions equivalent to those of Indonesia and the United Kingdom combined. In addition, its low density makes it difficult to store and transport — it must be under high pressure at all times. It’s also well-known for being highly flammable — its use as a fuel has come a long way since the Hindenburg Disaster but the association still makes many people nervous.

So there are quite a few problems. What’s the good news?

In the last few years, we've seen how rapidly investment, innovation, and infrastructure policy can completely transform individual renewable energy industries. For example, the IEA analysis believes the declining costs of renewables and the scaling up of hydrogen production could reduce the cost of producing hydrogen from renewable electricity 30% by 2030.

Some of the issues around expense could be resolved by mass manufacture of fuel cells, refuelling equipment, and electrolysers (which produce hydrogen from electricity and water), made more likely by the increased interest and urgency. Those same driving forces could improve infrastructural issues such as refuelling stations for private and commercial vehicles, although this is likely to require coordination between various stakeholders, including national and local governments, industry, and investors.

The significant gains in renewable energy mean that “green” hydrogen, where renewable electricity powers the electrolysis process, is within sight.

The IEA report makes clear that international co-operation is “vital” to progress quickly and successfully with hydrogen energy. R&D requires support, as do first movers in mitigating risks. Standards need to be harmonised, good practice shared, and existing international infrastructure built on (especially existing gas infrastructure).

If hydrogen can be as efficient and powerful a contributor to a green global energy mix as its proponents believe, then it's better to invest sooner rather than later. If that investment can help power a post-Covid economic recovery, even better.

The Organisation for Economic Cooperation and Development (OECD) defines the Blue Economy as ‘all economic sectors that have a direct or indirect link to the oceans, such as marine energy, coastal tourism and marine biotechnology.’ Other organisations have their own definitions, but they all stress the economic and environmental importance of seas and oceans.

Header image: Our oceans are of economic and environmental importance

To this end there are a growing number of initiatives focused on not only protecting the world’s seas but promoting economic growth. At the start of 2021 the Asian Development Bank (ADB) and the European Investment Bank (EIB) joined forces to support clean and sustainable ocean initiatives in the Asia-Pacific region, and ultimately contribute to achieving Sustainable Development Goals and the climate goals of the Paris Agreement.

Both institutions will finance activities aimed at promoting cleaner oceans ‘through the reduction of land-based plastics and other pollutants discharged into the ocean,’ as well as projects which improve the sustainability of all socioeconomic activities that take place in oceans, or that use ocean-based resources.

ADB Vice-President for Knowledge Management and Sustainable Development, Bambang Susantono, said ‘Healthy oceans are critical to life across Asia and the Pacific, providing food security and climate resilience for hundreds of millions of people. This Memorandum of Understanding between the ADB and EIB will launch a framework for cooperation on clean and sustainable oceans, helping us expand our pipeline of ocean projects in the region and widen their impacts’.

The blue economy is linked to green recovery

In the European Union the blue economy is strongly linked to the bloc’s green recovery initiatives. The EU Blue Economy Report, released during June 2020, indicated that the ‘EU blue economy is in good health.’ With five million people working in the blue economy sector during 2018, an increase of 11.6% on the previous year, ‘the blue economy as a whole presents a huge potential in terms of its contribution to a green recovery,’ the EU noted. As the report was launched, Mariya Gabriel, Commissioner for Innovation, Research, Culture, Education and Youth, responsible for the Joint Research Committee said; ‘We will make sure that research, innovation and education contribute to the transition towards a European Blue Economy.’

The impact of plastics in oceans is well known and many global initiatives are actively tackling the problem. At the end of 2020 the World Economic Forum and Vietnam announced a partnership to tackle plastic pollution and marine plastic debris. The initiative aims to help Vietnam ‘dramatically reduce its flow of plastic waste into the ocean and eliminate single-use plastics from coastal tourist destinations and protected areas.’ Meanwhile young people from across Africa were congratulated for taking leadership roles in their communities as part of the Tide Turners Plastic Challenge. Participants in the challenge have raised awareness of the impact of plastic pollution in general.

But it isn’t just the health of our oceans that governments and scientists are looking at. There is growing interest in the minerals and ore that could potentially be extracted via sea-bed mining. The European Commission says that the quantity of minerals occupying the ocean floor is potentially large, and while the sector is small, the activity has been identified as having the potential to generate sustainable growth and jobs for future generations. But adding a note of caution, the Commission says, ‘Our lack of knowledge of the deep-sea environment necessitates a careful approach.’ Work aimed at shedding light on the benefits, drawbacks and knowledge gaps associated with this type of mining is being undertaken.

With the push for cleaner energy and the use of batteries, demand for cobalt will rise, and the sea-bed looks to have a ready supply of the element. But, the World Economic Forum points out that the ethical dimensions of deep-sea cobalt have the potential to become contentious and pose legal and reputational risks for mining companies and those using cobalt sourced from the sea-bed.

Energy will continue to be harnessed from the sea.

But apart from its minerals, the ocean’s ability to supply energy will continue to be harnessed through avenues such as tidal and wind energy. During the final quarter of 2020, the UK Hydrographic Office launched an Admiralty Marine Innovation Programme. Led by the UK Hydrographic Office, the programme gives innovators and start-ups a chance to develop new solutions that solve some of the world’s most pressing challenges as related to our oceans.

The UK’s Blue Economy is estimated to be worth £3.2 trillion by the year 2030. Marine geospatial data will be important in supporting this growth by enabling the identification of new areas for tidal and wind energy generation, supporting safe navigation for larger autonomous ships, which will play a vital role in mitigating climate change, and more.

Where once a country might have wanted to strike gold, now hitting upon a hydrocarbon find feels like a prize. But finding a hydrocarbon is only the beginning of the process and might not be worth it — as Lebanon is discovering.

First, a little background: for some time, Lebanon has been experiencing an energy crisis. Without resources of their own, the industry (which is government-owned) is reliant on foreign imports, which are expensive. Electricity in early 2020 was responsible for almost 50% of Lebanon's national debt. Major blackouts were common.

This contributed to a spiralling financial crisis, prompting public protests and riots as the middle class disappeared and even wealthier citizens struggled. Before Covid-19 and the devastating August 2020 blast in Beirut, Lebanon was in crisis.

The idea that the country might be able to switch from foreign oil to local gas was understandably appealing, especially when a major find was literally right there on the Lebanese shore. In 2019, a consortium of Israeli and US firms discovered more than 8tcm of natural gas in several offshore fields in the Eastern Mediterranean, much of it in Lebanese waters.

SCIblog 22 February 2021 - Hydrocarbon resources - image of pigeon rocks raouche beirut lebanon

A hydrocarbon find off the Beirut coast has failed to live up to its early promise.

But a find is only the beginning. With trust in Lebanese politicians low (the country ranks highly in most government corruption indexes) and a system that has repeatedly struggled to deliver a stable government, there are additional difficulties, not least a delay in the licensing rounds and a lack of trust — both internally, from citizens, and externally, from potential bidders. Meanwhile, Lebanon's neighbours race ahead to exploit their own finds, which ratchets up tensions.

Amid all that, a drilling exploration managed to go ahead last summer. But the joint venture between Total, ENI, and Novatek, which operated a well 30km offshore Beirut and drilled to approximately 1,500 metres, did not bring back the hoped-for results. The results confirmed the presence of a hydrocarbon system generally but did not encounter any reservoirs of the Tamar formation, which was the target.

Offshore exploration is a long process, with a lot of challenges and uncertainties and Ricardo Darré, Managing Director of Total E&P Liban, said afterwards, "Despite the negative result, this well has provided valuable data and learnings that will be integrated into our evaluation of the area". But the faith national politicians have long put in the hydrocarbon find, selling it as an answer to all Lebanon's problems, seems to have only worsened the domestic situation since.

And domestic politics is just the start of the problems…

SCIblog 22 February 2021 - Hydrocarbon resources - image of oil pipeline desert qatar middle east

Unlike other countries in the Middle East, Lebanon has no pipeline infrastructure of its own.

Israel, Egypt, and Jordan already have pipelines, which go to Italy. Turkey is working with Libya on a pipeline. Lebanon has no pipeline infrastructure of its own yet, although Russia has storage facilities and pipelines in the country and an eye on possible competition in the gas market.

None of that is an issue if the supply is intended for domestic use but that might not be profitable enough for investors and the Lebanese government would struggle to underwrite production on its own. Cyprus has encountered similar issues exploiting its share of the find.

Lebanon has also set an ambitious goal of having 30% of domestic energy mix sourced from renewable energy by 2030. The hoped-for gas was intended to support the renewable energy mix but, with the clock ticking, it might be that priorities shift to focusing on renewables. The Covid-19 pandemic will significantly impact the budgets of drilling companies and the push for renewable energy, both from governments and investors, seems to be growing as a way to boost economic recovery.

It may be that, after all the excitement around the hydrocarbon find, Lebanon starts to look elsewhere for its energy provision.

We are increasingly conscious of the need to recycle waste products, but it is never quite so easy as rinsing and sorting your waste into the appropriate bins, especially when it comes to plastic.

Despite our best intentions, only around 16% of plastic is recycled into new products — and, worse, plastics tend to be recycled into low quality materials because transformation into high-value chemicals requires substantial amounts of energy, meaning the choices are either downcycling or prohibitively difficult. The majority of single-use plastics end up in landfills or abandoned in the environment.

This is a particular problem when it comes to polyolefins such as polyethylene (PE) and polypropylene (PP), which use cheap and readily available raw materials. Approximately 380 million tonnes of plastics are generated annually around the world and it is estimated that, by 2050, that figure will be 1.1 billion tonnes. Currently, 57% of this total are polyolefins.

Why are polyolefins an issue? The strong sp3 carbon–carbon bonds (essentially long, straight chains of carbon and hydrogen atoms) that make them useful as a material also make them particularly difficult to degrade and reuse without intensive, high energy procedures or strong chemicals. More than most plastics, downcycling or landfill disposal tend to be the main end-of-life options for polyolefins.

SCIblog 11 February 2021 - image of plastic waste in nature

Polyethylene is used to make plastic bags and packaging.

Now, however, a team of scientists from MIT, led by Yuriy Román-Leshkov, believe they may have made a significant step towards solving this problem.

Previous research has demonstrated that noble metals, such as zirconium, platinum, and ruthenium can help split apart short, simple hydrocarbon chains as well as more complicated, but plant-based lignin molecules, in processes with much lower temperatures and energy.

So the team looked at using the same approach for the long hydrocarbon chains in polyolefins, aiming to disintegrate the plastics into usable chemicals and natural gas. It worked.

First, they used ruthenium-carbon nanoparticles to convert more than 90% of the hydrocarbons into shorter compounds at 200 Celsius (previously, temperatures of 430–760 Celsius were required).

Next, they tested their new method on commercially available, more complex polyolefins without pre-treatment (an energy intensive requirement). Not only were the samples completely broken down into gaseous and liquid products, the end product could be selected by tuning the reaction, yielding either natural gas or a combination of natural gas and liquid alkanes (both highly desirable) as preferred.

SCIblog 11 February 2021 - image of plastic bottles on a beach

Polypropylene is used in bottle caps, houseware, and other packaging and consumer products.

The researchers believe that an industrial scale use of their method could eventually help reduce the volume of post-consumer waste in landfills by recycling plastics to desirable, highly valuable alkanes — but, of course, it's not that simple. The team says that more research into the effects of moisture and contaminants in the process is required, as well as product removal strategies to decrease the formation of light alkanes which will be critical for the industrialisation of this reaction.

However, they believe the path they're on could lead to affordable upcycling technology that would better integrate polyolefins into the global economy and incentivise the removal of waste plastics from landfill and the environment.

Introduction

The Industrial Decarbonisation Challenge (IDC) is funded by UK government through the Industrial Strategy Challenge Fund. One aim is to enable the deployment of low-carbon technology, at scale, by the mid-2020’s [1]. This challenge supports the Industrial Clusters Mission which seeks to establish one net-zero industrial cluster by 2040 and at-least one low-carbon cluster by 2030 [2]. This latest SCI Energy Group blog provides an overview of Phase 1 winners from this challenge and briefly highlights several on-going initiatives across some of the UK’s industrial clusters.

Phase 1 Winners

In April 2020, the winners for the first phase of two IDC competitions were announced. These were the ‘Deployment Competition’ and the ‘Roadmap Competition’; see Figure 1 [3].

 Phase 1 Industrial Decarbonisation Challenge

Teesside

Net-Zero Teesside is a carbon capture, utilisation and storage (CCUS) project. One aim is to decarbonise numerous carbon-intensive businesses by as early as 2030. Every year, up to 6 million tonnes of COemissions are expected to be captured. Thiswill be stored in the southern North Sea which has more than 1,000Mt of storage capacity. The project could create 5,500 jobs during construction and could provide up to £450m in annual gross benefit for the Teesside region during the construction phase [4].

The Humber

In 2019, Drax Group, Equinor and National Grid signed a Memorandum of Understanding (MoU) which committed them to work together to explore the opportunities for a zero-carbon cluster in the Humber. As part of this initiative, carbon capture technology is under development at the Drax Power Station’s bioenergy carbon capture and storage (BECCS) pilot. This could be scaled up to create the world’s first carbon negative power-station. This initiative also envisages a hydrogen demonstrator project, at the Drax site, which could be running by the mid-2020s. An outline of the project timeline is shown in Figure 3 [5].

North West

The HyNet project envisions hydrogen production and CCS technologies. In this project, COwill be captured from a hydrogen production plant as well as additional industrial emitters in the region. This will be transported, via pipeline, to the Liverpool Bay gas fields for long-term storage [6]. In the short term, a hydrogen production plant has been proposed to be built on Essar’s Stanlow refinery. The Front-End Engineering Design (FEED) is expected to be completed by March 2021 and the plant could be operational by mid-2024. The CCS infrastructure is expected to follow a similar timeframe [7].

For further information on the status of this project, click here.

Scotland

Project Acorn has successfully obtained the first UK COappraisal and storage licence from the Oil and Gas Authority. Like others, this project enlists CCS and hydrogen production. A repurposed pipeline will be utilised to transport industrial COemissions from the Grangemouth industrial cluster to St. Fergus for offshore storage, at rates of 2 million tonnes per year. Furthermore, the hydrogen production plant, to be located at St. Fergus, is expected to blend up to 2% volume hydrogen into the National Transmission System [8]. A final investment decision (FID) for this project is expected in 2021. It has the potential to be operating by 2024 [9].

In a recent paper published in Nature Climate Change, an international group of researchers are urging countries to reconsider their strategy to remove CO2 from the atmosphere. While countries signed up to the Paris Agreement have individual quotas to meet in terms of emissions reduction, they argue this cannot be achieved without global cooperation to ensure enough CO2 is removed in a fair and equitable way.

 harmful factory emissions

Harmful emissions

The team of international researchers from Imperial College London, the University of Girona, ETH Zürich and the University of Cambridge, have stated that countries with greater capacity to remove CO2 should be more proactive in helping those that cannot meet their quotas.

Co-author Dr Niall Mac Dowell, from the Centre for Environmental Policy and the Centre for Process Systems Engineering at Imperial, said, ‘It is imperative that nations have these conversations now, to determine how quotas could be allocated fairly and how countries could meet those quotas via cross-border cooperation.’

The team’s modelling and research has shown that while the removal quotas vary significantly, only a handful of countries will have the capacity to meet them using their own resources.

 reforestation

Reforestation

A few ways to achieve carbon dioxide removal:

(1)    Reforestation

(2)    Carbon Capture and Storage (CCS)  

(3)    CCS coupled to bioenergy – growing crops to burn for fuel. The crops remove CO2 from the atmosphere, and the CCS captures any CO2 from the power station before its release.

However, deploying these removal strategies will vary depending on the capabilities of different countries. The team have therefore suggested a system of trading quotas. For example, due to the favourable geological formations in the UK’s North Sea, the UK has space for CCS, and therefore, they could sell some of its capacity to other countries.

 Global cooperation

Global cooperation 

Co-lead author Dr Carlos Pozo from the University of Girona, concluded; ‘By 2050, the world needs to be carbon neutral - taking out of the atmosphere as much CO2 as it puts in. To this end, a CO2 removal industry needs to be rapidly scaled up, and that begins now, with countries looking at their responsibilities and their capacity to meet any quotas.’

Energy

Batteries have an important role as energy sources with environmental advantages. They offset the negative environmental impacts of fossil fuels or nuclear-based power; they are also recyclable. These attributes have led to increasing research with the aim of improving battery design and environmental impact, particularly regarding their end of life. In addition, there is a desire to improve battery safety as well as design batteries from more sustainable and less toxic materials.

New research shows that aluminium battery could offer several advantages:

Aluminium metal anode batteries could hold promise as an environmentally friendly and sustainable replacement for the current lithium battery technology. Among aluminium’s benefits are its abundance, it is the third most plentiful element the Earth’s crust.  

To date aluminium anode batteries have not moved into commercial use, mainly because using graphite as a cathode leads to a battery with an energy content which is too low to be useful.

This is promising for future research and development of aluminium as well as other metal-organic batteries.

New UK battery project is said to be vital for balancing the country’s electricity demand

Work has begun on what is said to be Europe’s biggest battery. The 100MW Minety power storage project, which is being built in southwest England, UK, will comprise two 50MW battery storage systems. The project is backed by China Huaneng Group and Chinese sovereign wealth fund CNIC. 

Shell Energy Europe Limited (SEEL) has agreed a multi-year power offtake agreement which will enable the oil and gas major, along with its recently acquired subsidiary Limejump, to optimise the use of renewable power in the area.

The major hurdles for battery design, states the EU’s document, include finding suitable materials for electrodes and electrolytes that will work well together, not compromise battery design, and meet the sustainability criteria now required. The process is trial and error, but progress is being made.

Introduction

In November 2020, the UK is set to host the major UN Climate Change summit; COP26. This will be the most important climate summit since COP21 where the Paris Agreement was agreed. At this summit, countries, for the first time, can upgrade their emission targets through to 20301. In the UK, current legislation commits government to reduce greenhouse gas emissions by at least 100% of 1990 levels by 2050, under the Climate Change Act 2008 (2050 Target Amendment)2.

Hydrogen has been recognised as a low-carbon fuel which could be utilised in large-scale decarbonisation to reach ambitious emission targets. Upon combustion with air, hydrogen releases water and zero carbon dioxide unlike alternative heavy emitting fuels. The potential applications of hydrogen span across an array of heavy emitting sectors. The focus of this blog is to highlight some of these applications, and on-going initiatives, across the following three sectors: Industry, Transport and Domestic.

Industry

Did you know that small-scale hydrogen boilers already exist?4

Through equipment modification, it is technically feasible to use clean hydrogen fuel across many industrial sectors such as: food and drink, chemical, paper and glass.

Whilst this conversion may incur significant costs and face technical challenges, it is thought that hydrogen-fuelled equipment such as furnaces, boilers, ovens and kilns may be commercially available from the mid-2020’s4.

Domestic

Did you know that using a gas hob can emit up to or greater than 71 kg of COper year?5

Hydrogen could be supplied fully or as a blend with natural gas to our homes in order to minimise greenhouse gas emissions associated with the combustion of natural gas.

As part of the HyDeploy initiative, Keele University, which has its own private gas network, have been receiving blended hydrogen as part of a trial study with no difference noticed compared to normal gas supply6.

Other initiatives such as Hydrogen 1007 and HyDeployare testing the feasibility of delivering 100% hydrogen to homes and commercial properties.

Transport

Did you know that, based on an average driving distance of approximately 11,500 miles per annum, an average vehicle will emit approximately 4.6 tonnes of COper year?9

In the transport sector, hydrogen fuel can be utilised in fuel cells, which convert hydrogen and oxygen into water and electricity.

Hydrogen fuel cell vehicles are already commercially available in the UK. However, currently, form only a small percentage of Ultra Low Emission Vehicle (ULEV) uptake10.

Niche applications of hydrogen within the transport sector are expected to show greater potential for hydrogen such as buses and trains. Hydrogen powered buses are already operational in certain parts of the UK and hydrogen trains are predicted to run on British railways from as early as 202211.

Summary

This blog gives only a brief introduction to the many applications of hydrogen and its decarbonisation potential. The purpose of which, is to highlight that hydrogen, amongst other low-carbon fuels and technologies, can play an important role in the UK’s transition to net-zero emissions.

Stay tuned for further SCI Energy Group blogs which will continue to highlight alternative low-carbon technologies and their potential to decarbonise.

Sustainability & Environment

Since the beginning of SCI Energy Group’s blog series, new legislation has come into place regarding emission targets. Instead of the previous 80% reduction target, the UK must now achieve net-zero emissions by 2050. This makes significant, rapid emission reduction even more critical. This article introduces the main sources of UK CO2 emissions across individual sectors.

The Big Picture

In 2018, UK CO2 emissions totalled to roughly 364 million tonnes. This was 2.4% lower than 2017 and 43.5% lower than 1990. The image below shows how much each individual sector contributed to the total UK carbon dioxide emissions in 2018. As can be seen, large emitting sectors include: energy supply, transport and residential. For this reason, CO2 emission trends from these sectors are discussed in this article.

Transport Sector

In 2018, the transport sector accounted for 1/3rd of total UK CO2 emissions. Since 1990, there has been relatively little change in the level of greenhouse gas emissions from this sector. Historically, transport has been the second most-emitting sector. However, due to emission reductions in the energy supply sector, it is now the biggest emitting sector and has been since 2016. Emission sources include road transport, railways, domestic aviation, shipping, fishing & aircraft support vehicles.

The main source of emissions are petrol and diesel in road transport. 

Ultra-low emission vehicles (ULEV) can provide emission reductions in this sector. Some examples of these include: hybrid electric, battery electric and hydrogen fuel cell vehicles. In 2018, there were 200,000 ULEV’s on the road in the UK. In addition to this, there was a 53% increase in ULEV vehicle registration compared to 2016. In 2018, UK government released the ‘Road to Zero Strategy’, which seeks to see 50% of new cars to be ULEV’s by 2030 and 40% of new vans.

Energy Supply Sector

In the past, the energy supply sector was the biggest emitting sector but, since 1990, this sector has reduced its greenhouse gas emissions by 60% making it the second-biggest emitting sector. Between 2017 and 2018, this sector accounted for the largest decrease in CO2 emissions (7.2%). Emission sources included fuel combustion for electricity generation and other energy production sources, The main sources of emission are use of natural gas and coal in power plants.

In 2015, the Carbon Price Floor tax changed from £9/tonne CO2 emitted to £18/ tonne CO2 emitted. This resulted in a shift from coal to natural gas use for power generation. There has also been a considerable growth in low-carbon technologies for power generation. All of these have contributed to emission reductions in this sector.

 Natural gas power plant

Figure 2 - Natural gas power plant

Residential Sector

Out of the total greenhouse gas emissions from the residential sector, CO2 emissions account for 96%. Emissions from this sector are heavily influenced by external temperatures. For example, colder temperatures drive higher emissions as more heating is required.

In 2018, this sector accounted for 18% of total UK CO2 emissions. Between 2017 and 2018, there was a 2.8% increase in residential emissions. Overall, emissions from this sector have dropped by 16% since 1990. Emission sources include fuel combustion for heating and cooking, garden machinery and aerosols. The main source of emission are natural gas for heating and cooking.

Summary

The UK has reduced CO2 emissions by 43.5% since 1990. However, further emission reductions are required to meet net-zero targets. The energy supply sector has reduced emissions by 60% since 1990 but remains the second biggest emitter. In comparison to this, emission reductions in the residential sector are minor. Yet, they are still greater than the transport sector, which has remained relatively static. Each of these sectors require significant emission reduction to aid in meeting new emission targets.

Energy

Having previously explored the various ways in which energy is supplied in the UK, this article highlights UK energy consumption by fuel type and the sectors it is consumed in. 

national grid

But before proceeding, it is important to first distinguish between the terms ‘primary energy consumption’ and ‘final energy consumption’. The former refers to the fuel type in its original state before conversion and transformation. The latter refers to energy consumed by end users.

Primary energy consumption by fuel type

 oil rig

Oil consumption is on the decline.

In 2018, UK primary energy consumption was 193.7 m tonnes of oil equivalent. This value is down 1.3% from 2017 and down 9.4% from 2010. This year, the trend has continued so far. Compared to the same time period last year, the first three months of 2019 have shown a declination of 4.4% in primary fuel consumption.

It is also important to identify consumption trends for specific fuels. Figure 1 below illustrates the percentage increases and decreases of consumption per fuel type in 2018 compared to 2017 and 2010.

 

Figure 1 shows UK Primary Energy Consumption by Fuel Type in 2018 Compared to 2017 & 2010. Figure: BEIS. Contains public sector information licensed under the Open Government Licence v1.0.

As can be seen in 2018, petroleum and natural gas were the most consumed fuels. However, UK coal consumption has dropped by almost 20% since 2017 and even more significantly since 2010. But perhaps the most noticeable percentage change in fuel consumption is that of renewable fuels like bioenergy and wind, solar and hydro primary electricity. 

In just eight years, consumption of these fuels increased by 124% and 442%, respectively, thus emphasising the increasingly important role renewables play in UK energy consumption and the overall energy system.

Final energy consumption by sector

Overall, the UK’s final energy consumption in 2018, compared to 2017, was 0.7% higher at a value of approximately 145 m tonnes of oil equivalent. However, since 2010, consumption has still declined by approximately 5%. More specifically, figure 2 illustrates consumption for individual sectors and how this has changed since.

 uk energy consumption statistics 2

Figure 2 from UK Final Energy Consumption by Sector in 2018 Compared to 2017 & 2010. Figure: BEIS. Contains public sector information licensed under the Open Government Licence v1.0.

Immediately, it is seen that the majority of energy, consumed in the UK, stems from the transport and domestic sector. Though the domestic sector has reduced consumption by 18% since 2010, it still remains a heavy emitting sector and accounted for 18% of the UK’s total carbon dioxide emissions in 2018. 

Therefore, further efforts but be taken to minimise emissions. This could be achieved by increasing household energy efficiency and therefore reducing energy consumption and/or switching to alternative fuels.

 loft insulation

Loft insulation is an example of increasing household energy efficiency.

Overall, since 2010, final energy consumption within the transport sector has increased by approximately 3%. In 2017, the biggest percentage increase in energy consumption arose from air transport. 

Interestingly, in 2017, electricity consumption in the transport sector increased by 33% due to an increased number of electric vehicles on the road. Despite this, this sector still accounted for one-third of total UK carbon emissions in 2018.  

 electric vehicle charging

Year upon year, the level of primary electricity consumed from renewables has increased and the percentage of coal consumption has declined significantly, setting a positive trend for years to come.


Energy

Energy is critical to life. However, we must work to find solution to source sustainable energy which compliments the UK’s emission targets. This article discusses six interesting facts concerning the UK’s diversified energy supply system and the ways it is shifting towards decarbonised alternatives.

Finite Resources

1. In 2015, UK government announced plans to close unabated coal-fired power plants by 2025.

In recent years, energy generation from coal has dropped significantly. In March 2018, Eggborough power station, North Yorkshire, closed, leaving only seven coal power plants operational in the UK. In May this year, Britain set a record by going one week without coal power. This was the first time since 1882!

2. Over 40% of the UK’s electricity supply comes from gas.

While it may be a fossil fuel, natural gas releases less carbon dioxide emissions compared to that of coal and oil upon combustion. However, without mechanisms in place to capture and store said carbon dioxide it is still a carbon intensive energy source.

3. Nuclear power accounts for approximately 8% of UK energy supply.

Nuclear power generation is considered a low-carbon process. In 2025, Hinkley Point C nuclear power-plant is scheduled to open in Somerset. With an electricity generation capacity of 3.2GW, it is considerably bigger than a typical power-plant.

Renewable Resources

In 2018, the total installed capacity of UK renewables increased by 9.7% from the previous year. Out of this, wind power, solar power and plant biomass accounted for 89%.

4. The Irish Sea is home to the world’s largest wind farm, Walney Extension.

 The Walney offshore wind farm

In addition to this, the UK has the third highest total installed wind capacity across Europe. The World Energy Council define an ‘ideal’ wind farm as one which experiences wind speed of over 6.9 metres per second at a height of 80m above ground. As can be seen in the image below, at 100m, the UK is well suited for wind production.

5. Solar power accounted for 29.5% of total renewable electricity capacity in 2018.

 solar panels

This was an increase of 12% from the previous year (2017) and the highest amount to date! Such growth in solar power can be attributed to considerable technology cost reductions and greater average sunlight hours, which increased by up to 0.6 hours per day in 2018. 

Currently, the intermittent availability of both solar and wind energy means that fossil fuel reserves are required to balance supply and demand as they can run continuously and are easier to control.

6. In 2018, total UK electricity generation from bioenergy accounted for approximately 32% of all renewable generation.

 A biofuel plant in Germany

This was the largest share of renewable generation per source and increased by 12% from the previous year. As a result of Lynemouth power station, Northumberland, and another unit at Drax, Yorkshire, being converted from fossil fuels to biomass, there was a large increase in plant biomass capacity from 2017.


Energy

Today, most rockets are fueled by hydrazine, a toxic and hazardous chemical comprised of nitrogen and hydrogen. Those who work with it must be kitted up in protective clothing. Even so, around 12,000t of hydrazine is released into the atmosphere every year by the aerospace industry

Now, researchers are in the process of developing a greener, safer rocket fuel based on metal organic frameworks (MOFs), a porous solid material made up of clusters of metal ions joined by an organic linker molecule. Hundreds of millions of connections join in a modular structure.

Robin Rogers, formerly at McGill University, US, has worked with the US Air Force on hypergolic liquids that will burn when placed in contact with oxidisers, to try get rid of hydrazine. He teamed up with Tomislav Friščić at McGill who has developed ways to react chemicals ‘mechanochemically’ – without the use of toxic solvents.

The pair were interested in a common class of MOFs called zeolitic imidazole frameworks, or ZIFs, which show high thermal stability and are usually not thought of as energetic materials.

 chemist working

They discussed the potential of using ZIFs with the imidazolate linkers containing trigger groups. These trigger groups allowed them to take advantage of the usually not accessible energetic content of these MOFs.

The resulting ZIF is safe and does not explode, and it does not ignite unless placed in contact with certain oxidising materials, such as nitric acid, in this case.

 danger sign

Authorities continue to use hydrazine because it could cost millions of dollars to requalify new rocket fuels, says Rogers. MOF fuel would not work in current rocket engines, so he and Friščić would like to get funding or collaborate with another company to build a small prototype engine that can use it.

This is the first in a series of blog articles by SCI’s Energy group. As a group, they recognise that the energy crisis is a topic of large magnitude and therefore have set out to identify potential decarbonisation solutions across multiple dimensions of the overall energy supply chain, which include source, system, storage and service.

Global emissions

 factory burning fossil fuels

The burning of fossil fuels is the biggest contributor to global greenhouse gas emissions.

According to the National Oceanic and Atmospheric Administration (NOAA), by the end of 2018, their observatory at Muana Loa, Hawaii, recorded the fourth-highest annual growth of global CO2 emissions the world has seen in the last 60 years.

Adding even more concern, the Met Office confirmed that this trend is likely to continue and that the annual rise in 2019 could potentially be larger than that seen in the previous two years.

Large concentrations of COin the atmosphere are a major concern because it is a greenhouse gas. Greenhouse gases absorb infrared radiation from solar energy from the sun and less is emitted back into space. Because the influx of radiation is greater than the outflux, the globe is warmed as a consequence.

Although CO2 emissions can occur naturally through biological processes, the biggest contributor to said emissions is human activities, such as fossil fuel burning and cement production.

Climate Change

Weather impacts from climate change include drought and flooding, as well as a noticeable increase in natural disasters.

This warming has resulted in changes to our climate system which has created severe weather impacts that increase human vulnerability. One example of this is the European heat wave and drought which struck in 2003. 

The event resulted in an estimated death toll of over 30,000 lives and is recognised as one of the top 10 deadliest natural disasters across Europe within the last century.

In 2015, in an attempt to address this issue, 195 nations from across the globe united to adopt the Paris Agreement which seeks to maintain a global temperature rise of well below 2C, with efforts to  limit it even further to 1.5C.

In their latest special report, the Intergovernmental Panel on Climate Change (IPCC) explained that this would require significant changes in energy, land, infrastructure and industrial systems, all within a rapid timeframe.

In addition, the recently published Emissions Gap report urged that it is crucial that global emissions peak by 2020 if we are to succeed in meeting this ambitious target.


Are we further away then we think?

 co2 graphic

As well as the Paris Agreement, the UK is committed to the Climate Change Act (2008) which seeks to reduce greenhouse gas emissions by at least 80% by 2050 relative to 1990 baseline levels. Since 1990, the UK has cut emissions by over 40%, while the economy has grown by 72%.

To ensure that we meet our 2050 target, the government has implemented Carbon Budgets, which limit the legal emissions of greenhouse gases within the UK across a five-year period. Currently, these budgets run up to 2032 and the UK is now in the third budget period (2018-2022).

The UK has committed to end the sale of all new petrol and diesel cars by 2040.

At present, the UK is on track to outperform both the second and third budget. However, it is not on track to achieve the fourth budget target (2023-2027). To be able to meet this, the Committee on Climate Change (CCC) urge that UK emissions must be reduced annually by at least 3% from this point forward.

We may not be sure which technologies will allow such great emission reductions, but one thing is for certain – decarbonisation is essential, and it must happen now!

‘Biodegradable plastics have become more cost-competitive with petroleum-based plastics and the demand is growing significantly, particularly in Western Europe, where environmental regulations are the strictest,’ says Marifaith Hackett, director of specialty chemicals research at analysts IHS Markit. The current market value of biodegradable plastics is set to exceed $1.1bn in 2018, but could reach $1.7bn by 2023, according to IHS Markit’s new report.

In 2018, the report finds that global demand for these polymers is 360,000t, but forecasts an average annual growth rate of 9% for the five years to 2023 – equivalent to a volume increase of more than 50%. Western Europe holds the largest share (55%) of the global market, followed by Asia, and Australia and New Zealand (25%), then North America (19%).

In another report released in May 2018, the US Plastics Industry Association (PLASTICS) was similarly optimistic, finding that the bioplastics sector (biodegradables made from biological substances) is at ‘a growth cycle stage’. It predicts the US sector will outpace the US economy as a whole by attracting new investments and entrants, while also bringing new products and manufacturing technologies to make bioplastics ‘more competitive and dynamic’.

As bioplastics product applications continue to expand, the dynamics of industry growth will continue to shift, the report notes. Presently, packaging is the largest market segment at 37%, followed by bottles at 32%. Changes in consumer behaviour are expected to be a significant driver.

Changes in US tax policy, particularly the full expensing of capital expenditure, should support R&D in bioplastics,’ says Perc Pineda, chief economist at PLASTICS. ‘The overall low cost of energy in the US complements nicely with R&D activities and manufacturing, which generates a stable supply of innovative bioplastic products.’ He points, for example, to efforts by companies and collaborations to develop and launch, at commercial scale, a 100% bio-based polyethylene terephthalate (PET) bottle as a case in point. Most PET bottles currently contain around 30% bio-based material.

The UK’s efforts to move towards clean energy can be seen around the UK, whether it’s the wind turbines across the hills of the countryside or solar panels on the roofs of city skyscrapers. There is, however, a technology that most people will never see, and it is set to be one of the biggest breakthroughs in a low-carbon economy yet.

Deep in the North Sea are miles of offshore pipelines, once used to transport natural gas to the UK. The pipelines all lead to a hub called the St Fergus Gas Terminal – a gas sweetening plant used by industry – that sits on the coast of north-east Scotland.

This network has now been reimagined as a low-cost, full-chain carbon capture, transport and offshore storage that will provide the UK will a viable solution to permanent carbon capture and storage (CCS) called the Acorn project.

CCS is a process that takes waste CO2 produced by large-scale, usually industrial, processes and transports it to a storage facility. The site, likely to be underground, stops the waste CO2 from being released into the atmosphere, storing it for later use for another purpose, such as the production of chemicals for coatings, adhesives or jet fuel.

High levels of CO2 in the atmosphere have been linked to global warming and the damaging effects of climate change, and CCS is one of the only proven solutions to decarbonisation that industry can currently access.

Taking advantage of existing infrastructure means that the Acorn project is running at a much lower cost and risk to comparable projects and is expected to be up and running by 2023. It is hoped the project will bring competitiveness and job retention and creation across the UK, particularly in the industrial centres of Scotland.  


Energy

Engineers say they have demonstrated a cost-effective way to remove carbon dioxide from the atmosphere. The extracted  CO2 could be used to make new fuels or go to storage.

The process of direct air capture (DAC) involves giant fans drawing ambient air into contact with an aqueous solution that traps CO2 . Through heating and several chemical reactions, CO2 is re-extracted and ready for further use.

‘The carbon dioxide generated via DAC can be combined with sequestration for carbon removal, or it can enable the production of carbon-neutral hydrocarbons, which is a way to take low-cost carbon-free power sources like solar or wind and channel them into fuels to decarbonise the transportation sector,’ said David Keith, founder of Carbon Engineering, a Canadian clean fuels enterprise, and a Professor of Physics at Harvard University, US.

DAC is not new, but its feasibility has been disputed. Now, Carbon Engineering reports how its pilot plant in British Columbia has been using standard industrial equipment since 2015. Keith’s team claims that a 1 Mt- CO2 /year DAC plant will cost $94-$232/ton of  CO2 captured. Previous theoretical estimates have ranged up to $1000/ton.

We begin our new series breaking down key innovations in agriculture with the Haber-Bosch process, which enabled large-scale agriculture worldwide. 

Nitrogen is essential to plant growth, but its natural production, through the decay of organic matter, cannot replenish nitrogen in soils quickly enough to keep up with the demands of agriculture. 

Ammonia – a compound of nitrogen and hydrogen – is therefore a key ingredient in fertilisers, allowing farmers to replenish the soil with nitrogen at will. As well as fertilisers, ammonia is used in pharmaceuticals, plastics, refrigerants, explosives, and in numerous industrial processes. 

But how is it made? At the turn of the 20th Century, ammonia was mostly mined from deposits of niter (also known as saltpetre – the mineral form of potassium nitrate), but the known reserves would not satisfy predicted demands. Researchers had to find alternative sources. 

 Fritz Haber left and Carl Bosch right

Fritz Haber (left) and Carl Bosch (right) created and commercialised the process.

Atmospheric nitrogen, which makes up almost 80% of air, was the obvious feedstock – its supply, to all intents and purposes, being infinite. But reacting atmospheric nitrogen, which is exceptionally stable owing to its strong triple bonds, posed a challenge for chemists globally.

In 1905, German chemist Fritz Haber cracked the riddle of fixing nitrogen from air. Using high pressure and an iron catalyst, Haber was able to directly react nitrogen and hydrogen gas to create liquid ammonia. 

His process was soon scaled up by BASF chemist and engineer Carl Bosch, becoming known as the Haber-Bosch process, and this would lead to the mass production of agricultural fertilisers and a phenomenal increase in the growth of crops for human consumption.

The Haber-Bosch process is conducted at a high pressure of 200 atmospheres and reaction temperatures of 450°C. It also requires a large feedstock of natural gas, and there is a global research and development effort to replace the process with a more sustainable alternative – just as the Haber-Bosch process replaced niter mining over a century ago.

A 3D battery made using self-assembling polymers could allow devices like laptops and mobile phones to be charged much more rapidly.

Usually in an electronic device, the anode and cathode are on either side of a non-conducting separator. But a new battery design by Cornell University researchers in the US intertwines the components in a 3D spiral structure, with thousands of nanoscale pores filled with the elements necessary for energy storage and delivery.

This type of ‘bottom-up’ self-assembly is attractive because it overcomes many of the existing limitations in 3D nanofabrication, enabling the rapid production of nanostructures at large scales.

In the Cornell design, the battery’s anode is made of gyroidal (spiral) thin films of carbon, generated by block copolymer self-assembly. They feature thousands of periodic pores around 40nm wide. The pores are coated with a 10 nm-thick separator layer, which is electronically insulating but ion-conducting. Some pores are filled with sulfur, which acts as the cathode and accepts electrons but doesn’t conduct electricity.

‘This is potentially ground-breaking, if the process can be scaled up and the quality of the electrodes can be ensured,’ comments Yury Gogotsi, director of A.J. Drexel Nanomaterials Institute, Philadelphia, US. ‘But this is still an early-stage development, proof of concept. The main challenge is to ensure that no short-circuits occur in the structure.

Figures on global data availability and growth are staggering. Data are expected to grow by an astounding factor of 300 between 2005 and 2020, and are predicted to reach 40 trillion bytes by 2020. This creates significant opportunities for data-based decision-making in industries such as agriculture.

Indeed, ongoing developments in precision agriculture and web-based apps can help the farmer to greatly enhance their efficiency, productivity and sustainability, and to prepare themselves for potentially catastrophic climatic events in real time.

On the other hand, farmers have traditionally relied on a more conventional approach for monitoring and improving their performance, namely, benchmarking. In a nutshell, benchmarking is about comparing one’s performance to that of their peers in terms of one or more performance indicators, typically expressed as ratios – i.e. output over input.

For instance, a dairy farmer may want to know how far their milk production per cow is from the top 10% of farms, or whether farms with a different management strategy than theirs (e.g. pasture-based farm vs. all-year housed system) could deliver higher milk yields. Farm benchmarking reports are standard practice in agricultural extension and consultancy.

However, these reports can be overly simplistic, because partial performance ratios cannot capture the multifaceted nature of agricultural sustainability, encompassing environmental (e.g. carbon footprints), social (e.g. labour use) and other indicators (e.g. animal health and welfare), in addition to economic and technical ones.

Renewables outstripped coal power for the first time in electricity generation in Europe in 2017, according to a new report. The European Power Sector in 2017 – by think-tanks Sandbag and Agora Energiewende – predicts renewables could provide half of Europe’s electricity by 2030.

Wind, solar and biomass generation collectively rose by 12% in 2017 – to 679 Terawatt hours  – generating 21% of Europe’s electricity and contributing to 30% of the energy mix. ‘This is incredible progress considering just five years ago coal generation was more than twice that of wind, solar and biomass,’ the report says.

However, growth is variable. The UK and Germany alone contributed to 56% of the expansion in the past three years. There is also a ‘bias’ for wind, with a 19% increase in 2017, due to good wind conditions and huge investments, the report says. 

‘This is good news now the biomass boom is over, but bad news in that solar was responsible for just 14% of the renewables growth in 2014 to 2017.’

New analysis by trade group WindEurope backs up the findings on wind power, showing that countries across Europe installed more offshore capacity than ever before: 3.14GW. This corresponds to 560 new offshore wind turbines across 17 wind farms. Fourteen projects were fully completed and connected to the grid, including the first floating offshore wind farm. Europe now has a total installed offshore wind capacity of 15.78GW.

Germany remains top of the European league, with the largest total installed wind-power capacity; worth 42% of the EU’s new capacity in 2017, followed by Spain, the UK, and France. Denmark boasts the largest share of wind in its power mix at 44% of electricity demand.

Renewable energy has long been known as a greener alternative to fossil fuels, but that doesn’t mean that the former has no negative environmental impacts. Hydropower, for instance, has been known to reduce biodiversity in the land used for its systems.

Now, a team of Norwegian-based researchers have developed a methodology that quantifies the environmental effects of hydropower electricity production.

UllaFrre

Ulla-Førre – Norway’s largest hydropower station.

Martin Dorber, PhD candidate in Industrial Ecology at the Norwegian University of Science and Technology (NTNU), is part of the team that developed the analytic tool. ‘Some hydropower reservoirs may look natural at first. However, they are human-influenced and if land has been flooded for their creation, this may impact terrestrial ecosystems,’ he said,

The Life Cycle Assessment, or LCA, can be used by industry and policymakers to identify the trade-offs associated with current and future hydropower projects. Norway is one of the top hydropower producers in the world, with 95% of its domestic electricity production coming from hydropower.

Many hydropower facilities include a dam –  many purpose-built for hydropower generation – which stores fresh water from lakes or rivers in a reservoir.

Reducing biodiversity in the areas where hydropower development is being considered is one of the main disadvantages of the renewable source. Reduced freshwater habitats and water quality, and land flooding are among the damaging effects – all of which are difficult to assess, says the team.

‘Land use and land use change is a key issue, as it is one of the biggest drivers of biodiversity loss, because it leads to loss and degradation of habitat for many species,’ said Dorber.

Using reservoir surface area data from the Norwegian Water Resources and Water Resources Directorate and satellite images from the NASA-USGS Global Land Survey, the team were able to create a life cycle inventory that showed the amount of land needed to produce a kilowatt-hour of electricity.

‘By dividing the inundated land area with the annual electricity production of each hydropower reservoir, we calculated site-specific net land occupation values for the life cycle inventory,’ said Dorber.

‘While it’s beyond the scope of this work, our approach is a crucial step towards quantifying impacts of hydropower electricity production on biodiversity for life cycle analysis.’

While this study is exclusive to hydropower reservoirs in Norway, the team believe this analysis could be adopted by other nations looking to extend their hydropower development and assess the potential consequences.

‘We have shown that remote sensing data can be used to quantify the land use change caused by hydropower reservoirs,’ said Dorber. ‘At the same time our results show that the land use change differs between hydropower reservoirs.’

‘More reservoir-specific land use change assessment is a key component that is needed to quantify the potential environmental impacts.’

Energy

Hailed by some as the future of clean energy, nuclear fusion is an exciting area of research, supported in the UK by the Atomic Energy Authority (UKAEA) – a government department that aims to establish the UK as a leader in sustainable energy. Here are five things you need to know about nuclear fusion. 

1. It powers the sun.

Originally posted by science

Nuclear fusion occurs when two or more atomic nuclei of a low atomic number fuse to form a heavier nucleus at high energy, resulting in the release of a large amount of energy. However, it is only possible at an extremely high temperature and pressure, which means that currently the input energy required is too high to produce energy commercially. It’s the same process that powers the stars – the sun fuses 620 million tons of hydrogen and makes 606 million metric tons of helium every second. 


2. The largest successful reactor is in Oxford.

The Joint European Torus (JET) is managed by the UKAEA at the Culham Science Centre in Oxford, UK. JET is a tokamak – a donut-shaped vessel designed around centrally placed fusion plasma, a fourth fundamental state of matter after solid, liquid, and air, containing the charged particles essential for nuclear fusion to occur. 

Using strong magnetic fields, the tokamak confines the plasma to a shape that allows it to reach temperatures up to 20 times that of the sun. While still not commercially viable, it is the only operational reactor that can generate energy from nuclear fusion. 


3. JET’s successor is due to launch in 2025

The International Thermonuclear Experimental Reactor (ITER), based in Provence, southern France, is the EU’s successor project to JET – a collaboration between all 28 EU member states as well as China, India, Japan, South Korea, Russia, and the US. Its first experiment is due to run in 2025 and, if successful, it will be the world’s largest operating nuclear fusion reactor, producing upwards of 500MW. 


4. ITER is the feasibility study for large-scale, carbon-free energy

By 2025, ITER will produce its first plasma, with tritium and deuterium (a combination with an extremely low energy barrier) to be added in 2035, in the hope of allowing the facility to efficiently generate 100% carbon-free, reliable energy on a large scale. 


5. The UK’s future role in the nuclear sector rests on Brexit negotiations

Despite the UKAEA’s essential work in supporting the success of JET and continued commitment to investing in the project, Brexit makes the  continuation of JET and the UK’s role in ITER uncertain.

Director of ITER, Bernard Bigot, has said his concerns lie with the extension of JET. ‘If JET ends after 2018 in a way that is not coordinated with another global strategy for fusion development, clearly it will hurt ITER’s development,’ he said. ‘For me it is a concern.’

In a statement on the future of JET, the UK government said: ‘The UK’s commitment to continue funding the facility will apply should the EU approve extending the UK’s contract to host the facility until 2020.’

With hopes for JET’s funding to continue until at least 2023, and the UK government announcing its intentions to leave Euratom last year, the future of the UK’s ability to compete in the nuclear sector rests on the progress of Brexit negotiations in the coming months.

Determining the efficacy of organic solar cell mixtures is a time-consuming and tired practice, relying on post-manufacturing analysis to find the most effective combination of materials.

Now, an international group of researchers – from North Carolina State University in the US and Hong Kong University of Science and Technology – have developed a new quantitative approach that can identify effective mixtures quickly and before the cell goes through production.

By using the solubility limit of a system as a parameter, the group looked to find the processing temperature providing the optimum performance and largest processing window for the system, said Harald Ade, co-corresponding author and Professor of Physics at NC State.

‘Forces between molecules within a solar cell’s layers govern how much they will mix – if they are very interactive they will mix but if they are repulsive they won’t,’ he said. ‘Efficient solar cells are a delicate balance. If the domains mix too much or too little, the charges can’t separate or be harvested effectively.’

‘We know that attraction and repulsion depend on temperature, much like sugar dissolving in coffee – the saturation, or maximum mixing of the sugar with the coffee, improves as the temperature increases. We figured out the saturation level of the ‘sugar in the coffee’ as a function of temperature,’ he said.

Organic solar cells are a type of photovoltaic –  which convert energy from the sun into electrons – that uses organic electronics to generate electricity. This type of cell can be produced cheaply, and is both lightweight and flexible, making it a popular option for use in solar panels.

 Photovoltaic systems

However, difficulties in the production process, including an effective process to determine efficiency of potential material combinations, is stalling its development.

‘In the past, people mainly studied this parameter in systems at room temperature using crude approximations,’ said Long Ye, first author and postdoctoral researcher at NC State. ‘They couldn’t measure it with precision and at temperatures corresponding to processing conditions, which are much hotter.’

‘The ability to measure and model this parameter will also offer valuable lessons about processing and not just material pairs.’

But the process still needs refinement, said Ade. ‘Our ultimate goal is to form a framework and experimental basis on which chemical structural variation might be evaluated by simulations on the computer before laborious synthesis is attempted,’ he said.

 Tesla

Tesla is at the forefront of industrial battery technology research. 

Electric cars are accelerating commercially. General Motors has already sold 12,000 models of its Chevrolet Bolt and Daimler announced in September 2017 that it is to invest $1bn to produce electric cars in the US, with Investment bank ING, meanwhile, predicts that European cars will go fully electric by 2035.

‘Batteries are a global industry worth tens of billions of dollars, but over the next 10 to 20 years it will probably grow to many hundreds of billions per year,’ says Gregory Offer, battery researcher at Imperial College London. ‘There is an opportunity now to invest in an industry, so that when it grows exponentially you can capture value and create economic growth.’

The big opportunity for technology disruption lies in extending battery lifetime, says Offer, whose team at Imperial takes market-ready or prototype battery devices into their lab to model the physics and chemistry going on inside, and then figures out how to improve them.

Lithium batteries, the battery technology of choice, are built from layers, each connected to a current connector and theoretically generating equivalent power, which flows out through the terminals. However, improvements in design of packs can lead to better performance and slower degradation.

 Lithium batteries

For many electric vehicles, cooling plates are placed on each side of the battery cell, but the middle layers get hotter and fatigue faster. Offer’s group cooled the cell terminals instead, because they are connected to every layer. ‘You want the battery operating warmish, not too hot and not too cold,’ he says.

‘Keeping the temperature like that, we could get more energy out and extend the lifetime three-fold.’ If the expensive Li ion batteries in electric cars can outlive the car, he says their resale value will go up and dramatically alter the economic calculation when purchasing the car. ‘If we can get costs down, we will see more electric vehicles, and reduced emissions and improved air quality,’ Offer says.


Alternatives to lithium ion

Battery systems management and thermal regulation will allow current lithium batteries to be continually improved, but there are fundamental limits to this technology. ‘Lithium ion has a good ten years of improvements ahead,’ Offer predicts. ‘At that point we will hit a plateau and we are going to need technologies like lithium (Li) sulfur.’

Li sulfur has a theoretical energy density five times higher than Li ion. In September 2017, US space agency NASA said it will work with Oxis Energy in Oxford, UK, to evaluate its Li sulfur cells for applications where weight is crucial, such as drones, high-altitude aircraft and planetary missions.

However, Li sulfur is not the only challenger to Li ion. Toyota is working to develop solid-state batteries, which use solids like ceramics as the electrolyte. ‘They are based around a class of material that can conduct ions at room temperature as a solid,’ Offer explains. ‘The advantage is that you can then use metallic lithium as the anode. This means there is less parasitic mass, increasing energy density.’


Futuristic chemistries

For electric cars, the ultimate technology in terms of energy density is rechargeable metal-air batteries. These work by oxidising metals such as lithium, zinc or aluminium with oxygen from the air. ‘Making a rechargeable air breathing electrode is really hard,’ warns Offer. ‘To get the metal to give up the oxygen over and over again, it’s difficult.’ 

Development in the area looks promising, with the UK nurturing battery-focused SMEs and forward-thinking research groups in universities. The latest investment plan envisages support that links across research, innovation and scale-up, as championed by Mark Walport, the government’s Chief Scientific Advisor.

Introducing a programme to directly tackle this challenge ‘would drive improved efficiency of translation of UK science excellence into desirable economic outcomes; would leverage significant industrial investment in the form of a “deal” with industry; and would send a strong investment signal globally,’ says Walport.

Since taking office in late 2015, Argentinean president Mauricio Macri has prioritised investment in the energy sector to help reverse a costly energy deficit. Argentina’s abundant shale resources have attracted a growing number of major international companies, and attention has mostly been focused on the Vaca Muerta shale fields. Located in Patagonia they are one of the world’s largest reserves of shale gas.

The proposed investments revealed in YPF’s strategic plan for 2018-2022 indicate that the company intends to contribute $21.5bn directly, with the remainder coming from partnerships and associated companies.

YPF intends to ramp up oil production and continue the development of Argentina’s huge shale resources. The company said its non-conventional production is expected to grow by 150% over the period 2018-2022, with half of its hydrocarbon production coming from shale and tight oil and gas by 2022. The lifting of shale gas output will be helped by the continued fall in development costs.

Shale gas growth will increase the availability of natural gas liquids (NGLs) for chemical production. YPF estimates that the growth in shale gas will result in a 45% increase in its supply of NGLs between 2017 and 2022. YPF indicated that it has identified opportunities to invest in petrochemicals in Argentina, Brazil, Peru, Bolivia and Paraguay.

 Shale oil and gas

These investments would take advantage of the regional market imbalance together with shale gas growth, it said in its strategic plan, presented to investors in October 2017. ‘The region is a net petrochemical importer with room for a world scale complex,’ it added. 

There is room for one or two more ethylene sites, one or two methanol sites and two or three urea sites in the region, according to YPF.

The company said it is also developing opportunities to stimulate demand for natural gas, because demand in Argentina is highly seasonal. Opportunities include power generation, exports to Chile, Uruguay and Brazil, as well as petrochemical investments.

 YPF

YPF is Argentina’s largest petrochemicals producer, with a capacity of 2.2m t/year. It has three plants, located in Ensenada, Plaza Huincul and Bahía Blanca. Output includes benzene, toluene, mixed-xylene, ortho-xylene, cyclohexane, solvents, methyl tert-butyl ether (MTBE), 1-butene, oxo alcohols, tert-amyl methyl ether (TAME), linear alkylbenzene (LAB), linear alkylbenzene sulfonate (LAS), polyisobutylene, maleic anhydride, methanol and urea. The Bahía Blanca site is operated by nitrogen fertiliser producer Profertil, a 50:50 joint venture with Canadian company Agrium.

Argentina’s potential for new petrochemicals investments was highlighted recently by Marcos Sabelli, president of the Latin American Petrochemical and Chemical Association (APLA).

Speaking at the Latin American Energy Organization’s Forum on Regional Energy Integration in Buenos Aires, he said development of the Vaca Muerta shale fields improves the potential for steady feedstock supplies. 

‘We are proposing that we replicate the US model,’ he said. The US shale boom enabled the US to move from an importer to an exporter of petrochemicals. ‘Argentina has this potential. There is feedstock, market and companies,’ he added.

YPF said it is the largest shale operator outside North America, with a daily production exceeding 67,400 barrels of oil equivalent. The company participates in 50% of Argentina’s Vaca Muerta shale gas and oil reserves area, with more than 550 producing wells; 168 are horizontal.

Conventional hydrocarbons will remain the basis of the company’s production, with the development of more than 29 projects and the drilling of more than 1600 wells, it said. YPF has three refineries, accounting for 50% of Argentina´s capacity.

The company expects its production of oil and gas to grow by 5%/year over the next five years, reaching 700,000 barrels of oil equivalent per day in 2022. Exploration efforts will continue, with reserves targeted to rise by 50%. YPF also intends to boost its electricity production, much of it through renewables, as part of efforts to become a fully integrated energy company. YPF is pledging the investments at a time when President Macri’s pro-market government is on a drive to attract investments to consolidate an economic rebound after six years of stagnation.

Argentina’s GDP is forecast to grow by 2.9% in 2017 and 3.2% in 2018, according to the Organisation for Economic Co-operation and Development (OECD). The country’s shale gas boom, combined with economic growth, could make it an attractive candidate for a major new petrochemicals project.

Installing new energy infrastructure on the Isles of Scilly, UK, is a tricky proposition, given the islands’ location 28 miles off the Cornish coast, and a population of just 2,500 to share the high costs. 

But an exciting new project is about to transform the islands’ energy provision, reducing energy costs and supporting clean growth, through the use of a smart energy grid.

By 2025, the Smart Islands programme aims to provide the Isles of Scilly with 40% of its electricity from renewables, cut Scillonians’ electricity bills by 40%, and revolutionise transport, with 40% of cars to be electric or low-carbon. The key to this will be an integrated smart energy system, operated by a local community energy services company and monitored through an Internet of Things platform.

 Local Growth Fund

In the UK Government’s Industrial Strategy, published in November 2017, it was announced that the Local Growth Fund would provide £2.95m funding to the project, via the Cornwall and Isles of Scilly Local Enterprise Partnership.

The project will be led by Hitachi Europe Ltd in a public-private partnership, along with UK-based smart energy technology company Moixa, and smart energy software company PassivSystems.

 

Colin Calder, CEO of PassivSystems, explained, ‘Our scalable cloud-based energy management platform will be integrated with a range of domestic and commercial renewable technologies, allowing islanders to reduce their reliance on imported fossil fuels, increase energy independence and lower their carbon footprint.

‘These technologies have the potential to significantly increase savings from solar PV systems.’

Aiming to increase the renewable capacity installed on the island by 450kW and reduce greenhouse gas emissions by 897 tonnes CO2 equivalent per annum, 100 homes on the islands (a tenth of the total) will be fitted with rooftop solar photovoltaic systems, and two 50kW solar gardens will also be built.

100 homes will also get energy management systems, and 10 of them will pilot a variety of additional smart energy technologies such as smart batteries and air source heat pumps.

 

Chris Wright, Moixa Chief Technology Officer, said: ‘Ordinary people will play a key role in our future energy system. Home batteries and electric vehicles controlled by smart software will help create a reliable, cost-effective, low-carbon energy system that will deliver savings to homeowners and the community.

‘Our systems will support the reduction of fuel poverty on the Scilly Isles and support their path to full energy independence. They will be scalable and flexible so they can be replicated easily to allow communities all over the world to cut carbon and benefit from the smart power revolution.’

The burgeoning smart energy industry is attracting serious investment – only this week, the Department for Business, Energy and Industrial Strategy (BEIS) announced it will invest up to £8.8 million in new ideas for products and services that use smart meter data to reduce energy demand in small, non-domestic buildings; while Manchester-based smart energy start-up Upside Energy this week announced it had secured £5.5m in its first round of venture capital financing to commercialise and deploy its cloud-based smart grid platform.

Smart energy covers a range of technologies intended to allow both companies and households to increase their energy efficiency. Smart meters are currently being offered by energy suppliers, with the aim of allowing energy companies to automatically manage consumer energy use to reduce bills, for example, running your washing machine when energy demand (and therefore cost) is low. 

Battery technology also plays a major role in smart energy, allowing users to store renewable power and potentially even sell back into the grid as demand requires. In the Industrial Strategy, the government announced a new £80m National Battery Manufacturing Development Facility (NBMD) in Coventry, which will bring together academics and businesses to work on new forms and designs of batteries, as well as their chemistry and components.

The funding for this and a further £40m investment into 27 individual battery research projects have been allocated from the £246m Faraday Challenge, which was announced in July.

The Smart Islands project promises a real-world demonstration of how a community can harness the power of the Internet of Things to maintain an efficient, inexpensive, and clean energy system. 

Agrifood

Russian researchers have developed new fertilisers based on nanopowders of transition metals. In field trials on agricultural crops, harvests increased by more than a quarter, compared with conventional fertilisers.

Iron, cobalt and copper affect a plant’s level of resistance to pests and diseases. These microelements are typically introduced into the soil as soluble salts, but rain and irrigation can wash them away, requiring further applications. They also have potential to disrupt local ecosystems as they pass into the groundwater.

The team, led by the National University of Science and Technology (NUST) in Moscow, has developed a group of fertilisers that are applied as a powder to plant seeds, without losses to the soil or water systems. In this way, ‘the future plant is provided with a supply of necessary microelements at the stage of seeding,’ reports Alexander Gusev, head of the project at NUST’s Department of Functional Nanosystems. 

‘[It’s] a one-seed treatment by a product containing the essential microelements in nanoform. These particles of transition metals – iron, copper, cobalt – have a powerful stimulating effect on plant growth in the initial growth phase.’

Gusev reports improved field germination and increased yields of 20-25%.

The main difficulty was to produce a powder from the nanoparticles, which tended to quickly stick together as aggregates, says Gusev – a problem they solved by using organic stabilisers and then subjecting the colloidal solutions to ultrasonic processing.

Gusev now wants to discvover how the new fertiliser acts in different soils, and in relation to different plant cultures. Its environmental safety also needs to be evaluated before widespread use, he adds.

But Steve McGrath, head of sustainable agricultural sciences at Rothamsted Research, is sceptical. Plants are adapted to take up ionic forms of these microelements, not nanoparticles, he says. ‘Also, seeds do not take up much micronutrients. Roots do that, and depending on the crop and specific nutrient, most uptake is near to the growing ends of the root, and throughout the growing season, when the seed and nearby roots are long gone.’

 fertiliser2

Critics are skeptical of the efficacy of the new kind of fertiliser. Image: Pexels

If there is an effect on crop yield, he thinks it is more likely to be due to the early antifungal and antibacterial effects of nanoparticles. ‘They have a large and highly reactive surface area and if they are next to membranes of pathogens when they react they generate free radicals that disrupt those membranes. So, in a soil that is particularly disease-infected, there may be some protection at the early seedling stage.’

A huge challenge faced in the pursuit of a mission to Mars is space radiation, which is known to cause several damaging diseases – from Alzheimer’s disease to cancer.

And soon, these problems will not just be exclusive to astronauts. Speculation over whether space tourism is viable is becoming a reality, with Virgin Galactic and SpaceX flights already planned for the near future. The former reportedly sold tickets for US$250,000.

But could questions over the health risks posed hinder these plans?

What is space radiation?

In space, particle radiation includes all the elements on the periodic table, each travelling at the speed of light, leading to a high impact and violent collisions with the nuclei of human tissues.

The type of radiation you would endure in space is also is different to that you would experience terrestrially. On Earth, radiation from the sun and space is absorbed by the atmosphere, but there is no similar protection for astronauts in orbit. In fact, the most common form of radiation here is electrochemical – think of the X-rays used in hospitals.

 The sun

The sun is just one source of radiation astronauts face in space. Image: Pixabay

On the space station – situated within the Earth’s magnetic field ­– astronauts experience ten times the radiation that naturally occurs on Earth. The station’s position in the protective atmosphere means that astronauts are in far less danger compared with those travelling to the Moon, or even Mars.

Currently, NASA’s Human Research Program is looking at the consequences of an astronaut’s exposure to space radiation, as data on the effects is limited by the few subjects over a short timeline of travel.

Radiation poses one of the biggest problems for space exploration. Video: NASA

However, lining the spacecraft with heavy materials to reduce the amount of radiation reaching the body isn’t as easy as a solution as it is seems.

‘NASA doesn’t want to use heavy materials like lead for shielding spacecraft because the incoming space radiation will suffer many nuclear collisions with the shielding, leading to the production of additional secondary radiation,’ says Tony Slaba, a research physicist at NASA. ‘The combination of the incoming space radiation and secondary radiation can make the exposure worse for astronauts.’


Finding solutions

As heavy materials cannot hamper the effects of radiation, researchers have turned to a more light-weight solution: plastics. One element – hydrogen – is well recognised for its ability to block radiation, and is present in polyethylene, the most common type of plastic.

Engineers have developed plastic-filled tiles, that can be made using astronauts rubbish, to create an extra layer of radiation protection. Water, which is already an essential for space flight, can be stored alongside these tiles to create a ‘radiation storm shelter’ in the spacecraft.

But research is still required. Plastic is not a strong material and cannot be used as a building component of spacecrafts.

Energy

Compared with other renewable energy resources – take solar or wind power as examples – tidal energy is still in the first stages of commercial development. But as the world moves towards a greener economy, tidal power is becoming more in demand in the competitive renewables market.

Currently, the very few tidal power plants in the world are based in Canada, China, France, Russia, South Korea, and the UK, although more are in development. Experts predict that tidal power has the potential to generate 700TWh annually, which is almost a third of the UK’s total energy consumption.


How does it work?

Tidal energy is produced by the natural movement of ocean waves during the rise and fall of tides throughout the day. Generally, generating tidal energy is easier in regions with a higher tidal range – the difference between high tide, when the water level has risen, and low tide, when levels have fallen. These levels are influenced by the moon’s gravitational pull.

 The moons gravitational pull

We are able to produce energy from this process using tidal power generators. These generators work similarly to wind turbines by drawing energy from the currents of water, and are either completely or partially submerged in water.

One advantage of tidal power generators is that water is denser than air, meaning that an individual tidal turbine can generate more power than a wind turbine, even at low currents. Tides are also predictable, with researchers arguing that it is tidal power is potentially a more reliable renewable energy source.

What is tidal power and how does it work? Video: Student Energy

There are three types of tidal energy systems: barrages, tidal streams, and tidal lagoons. Tidal barrages are structured similar to dams and generate power from river or bay tides. They are the oldest form of tidal power generation, dating back to the 1960s.

However, there is a common concern that generators and barrages can damage the environment, despite producing green energy. By creating facilities to generate energy, tidal power centres can affect the surrounding areas, leading to problems with land use and natural habitats.

Since then, technologies in tidal streams and lagoons have appeared, which work in the same fashion as barrages but have the advantage of being able to be built into the natural coastline – reducing the environmental impact often caused by the construction of barrages and generators.

However, there are no current large-scale projects with these two systems, and output is expected to be low, presenting a challenge to compete with more cost-effective renewable technologies.

Sustainability & Environment

Latin America is setting the pace in clean energy, led by Brazil and Mexico. Renewables account for more than half of electricity generation in Latin America and the Caribbean – compared with a world average of about 22% – according to the International Energy Agency. 

Brazil is one of the world’s leading producers of hydropower, while Mexico is a leader in geothermal power. Smaller countries in the region are also taking a lead. In Costa Rica, about 99% of the country’s electricity comes from renewable sources, while in Uruguay the proportion is close to 95%.

 The Itaipu hydroelectric dam2

At the same time, countries such as Chile, Brazil, Mexico and Argentina have adjusted their regulations to encourage alternative energy without having to offer subsidies. Some have held auctions for generation contracts purely for renewables.   

Latin America’s renewable energy production is dominated by an abundance of hydropower, but there is strong growth potential for other sources of renewable energy. Wind and solar power are expected to account for about 37% of the region’s electricity generation by 2040, compared with current levels of about 4%, according to a report from Bloomberg New Energy Finance (BNEF).
