Design for liquid hydrogen powered aircraft revealed

‘…By working with industry, we are showing that truly carbon-free flight could be possible with hydrogen a front-runner to replace conventional fossil fuels.’

The Aerospace Technology Institute (ATI) has unveiled a conceptual design for an aircraft fuelled by liquid hydrogen. It is said to be capable of flying 279 passengers halfway around the world non-stop. The concept for the ‘mid-sized aircraft’ has been developed under the FlyZero Project which is led by the ATI and funded by the UK Government.

The development was announced ahead of the fourth meeting of the Jet Zero Council, which is chaired by the UK Government’s Transport Secretary. The Jet Zero Council held its first meeting during the summer of 2020, and is tasked with tackling aviation emissions in line with the Government’s ambition to develop the first ever zero emissions long haul passenger planes.

UK Government Business Secretary Kwasi Kwarteng said; ‘…By working with industry, we are showing that truly carbon-free flight could be possible with hydrogen a front-runner to replace conventional fossil fuels.’

At the same time eight companies have secured a share of £15 million for development of their sustainable aviation fuels (SAF) under the Government’s Green Fuels, Green Skies competition. The winners include Advanced Biofuel Solutions which will work with a refinery and an engineering company to produce a detailed engineering design for a facility producing biocrude that can be upgraded to renewable aviation fuel. Based on Fischer-Tropsch technology, the plant will use 133 000 tonnes of waste as feedstock each year. Lanzatech UK will use its funding to support the FEED stage of a proposed SAF facility which will be located in Port Talbot, Wales. The facility will have an output in excess of 100 million litres of fuel based on ethanol from biogenic wastes and industry flue gases.

The Government said that all the selected projects have a ‘clear potential to produce SAF capable of reducing emissions by more than 70% on a lifecycle basis when used in place of conventional jet fuel.’
