Leading academics from Oxford University, Imperial College London, Loughborough University, and King's College London convened at the Oxford Thermofluids Institute to mark the official launch of an ambitious program focused on developing H₂-powered jet engines. The £9.5-MM project, backed by the Engineering and Physical Sciences Research Council (EPSRC), aims to transform aviation by achieving net-zero emissions by 2050.

The kick-off meeting outlined plans to tackle critical scientific challenges associated with using cryogenic liquid H₂ (LH₂) as fuel for gas turbines. H₂ is seen as pivotal for the future of sustainable aviation because it produces no carbon emissions when combusted, emitting only water.

Oxford University will play a significant role in the program, drawing extensively on its expertise in thermal management and materials science research through the Oxford Thermofluids Institute and Solid Mechanics and Materials Engineering Group. Oxford researchers will specifically investigate the fundamental physics of cryogenic fluid flow, including challenges related to heat transfer and the thermal management of H₂ fuel systems.

New facilities are being developed to address the fundamental science required to predict cryogenic H₂ flow, which will augment Oxford’s existing world-class experimental facilities and advanced measurement techniques.

Highlighting the critical need for innovation, Dr Andy Lawrence, Head of Engineering at EPSRC noted, “H₂-powered technology represents one of the most significant opportunities for the UK's engineering sector. EPSRC is delighted to support this ground-breaking research program, ensuring the UK remains at the forefront of global efforts to decarbonize aviation.”

The collaborative program demonstrates significant commitment and strategic investment in future-ready aviation technologies, reinforcing the UK's global leadership in aerospace innovation.

The program also benefits from substantial support and collaboration from key industry and international partners, including Rolls-Royce, Airbus, Honeywell, Zeroavia, Boeing, Parker Hannifin and the European Space Agency, amongst others. Notably, these partners provide direct contributions such as funded studentships, valuable industrial guidance, and critical testing facilities. Across the universities involved, more than 12 studentships are being supported, significantly enhancing training opportunities for future aerospace leaders.

Professor Aimee Morgans from Imperial College London emphasized the collaborative strength of the program, “Combining our expertise across multiple institutions allows us to tackle complex combustion dynamics and achieve low emissions without sacrificing engine performance.”
