The initiative to address scientific challenges in using cryogenic liquid hydrogen (LH2) as fuel for gas turbines has commenced. Hydrogen is considered crucial for sustainable aviation due to its zero carbon emissions, emitting only water when combusted.
"Our vision is clear: to replace conventional aviation fuel with hydrogen, thereby making mid-range commercial flights zero carbon. This programme will lay the fundamental scientific groundwork to realise that vision," stated Professor Peter Ireland from Oxford University's Department of Engineering Science, who led the grant application.
Oxford University will significantly contribute to the programme through its expertise in thermal management and materials science research via the Oxford Thermofluids Institute and Solid Mechanics and Materials Engineering Group. Researchers at Oxford will focus on understanding the physics of cryogenic fluid flow, addressing heat transfer and thermal management challenges in hydrogen fuel systems.
New facilities are being developed to enhance Oxford's existing experimental capabilities and measurement techniques, aiming to predict cryogenic hydrogen flow more accurately.
Dr Andy Lawrence, Head of Engineering at EPSRC, highlighted the importance of innovation: "Hydrogen-powered technology represents one of the most significant opportunities for the UK's engineering sector. EPSRC is delighted to support this ground-breaking research programme, ensuring the UK remains at the forefront of global efforts to decarbonise aviation."
Professor Felix Hofmann from Oxford University emphasized an interdisciplinary approach: "Understanding hydrogen uptake and thermal stresses in engine components is critical. Our interdisciplinary approach ensures we not only develop viable technology but also ensure its longevity and safety in commercial aviation."
The collaborative programme underscores a commitment to future-ready aviation technologies, reinforcing UK's leadership in aerospace innovation. It receives substantial support from industry partners like Rolls-Royce, Airbus, Honeywell, Zeroavia, Boeing, Parker Hannifin, and the European Space Agency. These partners contribute through funded studentships, industrial guidance, and testing facilities. Over 12 studentships across participating universities are enhancing training for future aerospace leaders.
Professor Aimee Morgans from Imperial College London remarked on collaboration: "Combining our expertise across multiple institutions allows us to tackle complex combustion dynamics and achieve low emissions without sacrificing engine performance."
Members from Oxford University, Imperial College London, Loughborough University, and King's College participated in the launch meeting held at the Oxford Thermofluids Institute.
