A new collaborative effort led by Oxford University, in partnership with Imperial College London, Loughborough University, and King's College London, is set to revolutionize sustainable aviation by developing hydrogen-powered jet engines. The project, funded with £9.5M from EPSRC, aims to achieve net-zero emissions in aviation by 2050. Hydrogen is considered pivotal for sustainable aviation as it emits only water when combusted, making mid-range commercial flights zero carbon. Oxford University's role in the initiative is crucial, leveraging its expertise in thermal management and materials science to address scientific challenges related to using cryogenic liquid hydrogen as fuel. The program involves research on cryogenic fluid flow, heat transfer, and thermal management of hydrogen fuel systems. Industry giants like Rolls-Royce and Airbus are part of the collaboration, providing support, guidance, and testing facilities. The interdisciplinary approach ensures the development of viable, safe technology for commercial aviation, with a focus on longevity. The program also supports over 12 studentships across the universities involved, enhancing training opportunities for future leaders in the aerospace industry. Through collaboration, the project aims to tackle complex combustion dynamics and achieve low emissions without compromising engine performance, reaffirming the UK's leadership in aerospace innovation and commitment to decarbonizing aviation.
