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.

Careers

This latest instalment of SCI Energy Group’s blog delves deeper into the working life of another one of its own members – Peter Reineck.

Peter is currently a consultant working alongside technology developers. Throughout this article, he shares insights into his career to date.

 Peter Reineck

Figure 1- Peter Reineck

Peter, can you please provide a brief introduction about yourself? 

I worked with a number of chemical and environmental service companies in the UK and Canada in commercial operations roles.

I now work as a consultant with technology developers to support market and business development.

Can you please explain how your job is aligned with the energy sector? 

I have a particular interest in advanced combustion systems with CO2 capture.

Most recently, I became involved in a new project to produce bio-based plastic that would replace fossil-based plastics in packaging and other applications.

Bio-based plastic has the advantage of producing biogenic CO2 if composted or sent for energy recovery at end of life.

In your current role, what are your typical day-to-day tasks?

Typically, my work involves communicating with stakeholders by phone and email and in meetings, assessing their responses and planning developments accordingly.

How has your education/previous experience prepared you for this role?

I would say that English language skills and a knowledge of science and chemistry in particular have been the most helpful in my career.

What is your favourite aspect of your current job role?

Consultancy works well for me as the focus is on business development activities; as well, the hours are flexible.

What is the most challenging part of your job? 

A high degree of self-discipline is required in order to meet deadlines.

So far, what is your biggest accomplishment/ achievement throughout your career? 

The most satisfying were moving a number of businesses forward into new markets and applications.

Figure 3 - Self-discipline is required to meet deadlines

In your opinion, what do you think is the biggest problem faced in this field of work at present? 

I think the biggest problem is regulatory changes which affect the potential market for new technologies for packaging and power generation.

These changes are governmental responses to activist claims which are not based on a holistic interpretation of a complete set of data.

What advice would you give someone who is seeking / about to enter the same field of work? 

A practical understanding of science and statistics is essential. Combined with, an ability to translate new technologies into solutions which are economically viable.


Science & Innovation

2019 has been declared by UNESCO as the Year of the Periodic Table. To celebrate, we are releasing a series of blogs about our favourite elements and their importance to the chemical industry. Today’s blog focuses on Nickel.

Nickel, a silvery-white lustrous metal with a slight golden tinge may be commonly known as a US five cent coin, however, today nickel is one of the most widely used metals. According to the Nickel Institute, the metal is used in over 300,000 various products. It is also commonly used as a catalyst for hydrogeneration, cathodes for batteries and metal surface treatments.

Nickel in batteries:

Historically, nickel has been widely used in batteries; nickel cadmium (NiCd) and in nickel metal hydride (NiMH) rechargeable batteries. These batteries were used in power tools and early digital cameras. Their success as batteries in portable devices became a stepping stone that led to the significant use of NiMH batteries in car vehicles, such as the Toyota Prius.

The demand for nickel will increase even further as we move away from fossil fuel energy. More energy wll need to be stored in the cathode part of lithium-ion batteries as a result.

Socio-economic data on nickel demonstrates the importance the nickel value chain has on industries, which includes mining through end use to recycling.

The data reflects that globally, the nickel value chain supports a large number of jobs, primarily ones in manufacturing and chemical engineering. The output generated by nickel related industries is approximately €130bn, providing around 750,000 jobs.

Nickel is fully recyclable without its qualities being downgraded, making it very sustainable. It is difficult to destroy and its qualities – corrosion resistance, high-temperature stability, strength, recyclability, and catalytic and electromagnetic properties are enabling qualities required for sustainability.

Jenny Gracie was awarded a Messel Travel Bursary for an internship with the Naked Scientists based at the University of Cambridge. Here she describes how her internship has helped her to develop her skills and confidence in science communication, which she can now use to help shape her future career.

I am currently in the final year of a PhD in Chemistry at the University of Strathclyde. My project seeks to better treat cardiovascular disease, which is still the world’s leading cause of death. I am working towards a drug delivery system which utilises hollow gold nanoparticles as a ‘vehicle’ for delivering statins to the fatty plaques that block the arteries. Although I’m still interested in my research project, I’ve developed a real enthusiasm for science communication over the last few years and would like pursue a career in this field.

As a STEM ambassador I have attended fairs, festivals and schools to help spark a curiosity in science among children. During my PhD, the opportunity of an eight-week internship with The Naked Scientists came up, and I simply couldn’t let it pass. Without the funding support from SCI I could not have taken the internship, and so I am extremely grateful for the Messel Travel Bursary, and I know that this contribution helped make this transformative career experience a reality.

The Naked Scientists are an award-winning science production group based at the University of Cambridge. They create one of the world’s most popular science shows, achieving over 50m downloads in the last five years. They broadcast weekly on BBC Cambridgeshire, BBC 5Live, ABC National Radio in Australia and also publish a podcast of the show. Podcasts are free, available on-demand and are a widely accessible source of science information to the general public. The Naked Scientist internship programme develops the skill set of early career communicators and provides first-hand experience in the world of science media communication.

Podcast production has grown exponentially in the last few years, however chemistry still remains underrepresented compared to the other traditional physical sciences, like physics and biology. As a chemist who is interested in a career in science communication, this role has allowed me to gain the necessary skills to make my own podcasts in the future.

As an intern I was part of the production team from the first day! It was a catapult into the world of radio broadcast and podcast production, but perfect for understanding how a show is produced from scratch. Our weekly show consisted of two parts – one half would cover the news and recently published articles, and the second half would cover a specific topic within science.

Media privileges gave me access to all the journals to be published that week, with them sealed under embargo until publication. We tended to pick articles that have a global impact and capture the interest of the listener. Each team member would be assigned an article, and we would then have to contact the authors to scope the story and arrange a recorded interview. The skills I required to organise and execute a good interview improved over the course of the eight weeks. I could see a real development in both my style and confidence.

During the internship I also learned how to use software to edit audio, and stitch together multiple tracks to create build pieces with music and sound effects. To accompany the interview, each week we also wrote a short article on the research. This required converting high-level science into a form that could be understood by the general public… something that is much harder than it sounds!


Energy

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.
