The University of Manchester is part of a UK-led consortium, along with other top universities and industry partners, working on cutting-edge hydrogen fuel cell technologies for zero-emissions aviation. This collaborative effort aims to tackle the technical challenges of implementing hydrogen-fuelled aircraft to combat the significant greenhouse gas emissions produced by the aviation sector. Led by GKN Aerospace, the consortium's projects like H2GEAR, HyFIVE, and H2flyGHT are focused on developing hydrogen-powered aircraft technologies for varying flight ranges. These projects utilize hydrogen fuel cells to generate electricity from liquid hydrogen, offering a cleaner and more efficient means of propulsion. The H2GEAR programme, with a strong contribution from The University of Manchester, is pioneering cryogenic cooling techniques to increase energy efficiency in propulsion systems. Chief Technology Officer at GKN Aerospace, Russ Dunn, emphasizes the importance of hydrogen-powered aircraft in reducing emissions and keeping the world connected. The H2GEAR programme is set to conclude in 2025 and could potentially bring significant economic benefits to the UK aerospace sector. The article highlights that hydrogen-powered aviation is crucial for a sustainable future and positions the UK as a global leader in sustainable aviation innovation.
