Hydrogen’s potential as the future fuel for aviation is no longer a distant dream, thanks to the formation of the Hydrogen in Aviation (HIA) alliance. This collaboration of critical stakeholders—easyJet, Rolls-Royce, Airbus, Ørsted, GKN Aerospace, and Bristol Airport—aims to advance zero-carbon aviation in the UK.
The Aim of the HIA Alliance
A key initiative in the UK’s strategy for green aviation, the HIA aims to:
- Push for the UK’s dominance in hydrogen-powered aviation.
- Highlight hydrogen as the prime candidate for decarbonizing the aviation sector. Importantly, they explore other options like sustainable aviation fuels (SAF), synthetic fuels, and batteries.
- Advocate for the required infrastructure and policy enhancements to support carbon-free flight.
Advances in Hydrogen-Powered Aviation
Several advancements underscore the UK’s readiness for hydrogen:
- Airbus is engineering new hydrogen-powered aircraft, aiming for them to commence commercial service by 2035.
- After successful ground tests in 2022, Rolls-Royce has shown that jet engines can run on hydrogen.
- Startups like ZeroAvia and Universal Hydrogen made significant strides with their hydrogen-powered aircraft. They have already conducted flight tests.
With such significant research and development backing, the HIA will collaboratively draft a clear route to achieving hydrogen-fueled aviation in the UK.
The Economic Promise of Hydrogen-Power
Johan Lundgren, CEO of easyJet and the inaugural Chair of HIA, sheds light on the potential.
“There is no doubt that the UK has the potential to become a world leader in hydrogen aviation, which could bring with it a £34bn per annum boost to the country’s economy by 2050, but in order to capture this opportunity, rapid change is needed and the time to act is now.
“We must work together to deliver the radical solutions required for a hard to abate industry like aviation so we can protect and maximise the benefits that it brings to the UK economy and society and that we know British consumers want to be preserved.
“HIA looks forward to working with the UK Government to ensure the right funding, regulatory and policy changes are implemented to accelerate the delivery of zero carbon aviation.”
Engine Technology for Hydrogen-Powered Aviation
Grazia Vittadini, Chief Technology Officer at Rolls-Royce, said of the engine technology required to power flights with hydrogen :
“Collaboration is key when it comes to achieving our net zero ambitions as an industry, which is why we are proud to be part of the Hydrogen in Aviation Alliance. Our contribution to HIA is our capability and experience in pioneering new technologies and solutions – we have already tested a modern aero engine on green hydrogen, and we strongly believe it is one of the solutions that will help decarbonize aviation in the mid-to-long term.”
Aircraft Technology Advances
Sabine Klauke, Chief Technology Officer at Airbus said of aircraft development:
“As Airbus continues to mature the aircraft technologies needed to deliver hydrogen-powered flight, a united industry voice is needed to secure a robust ecosystem of renewable sourced hydrogen. Joining our peers from across the UK aviation landscape in a targeted approach to policy and investment action brings us closer to a decarbonized future of flying.”
Ensuring Green Hydrogen Supply
Olivia Breese, Senior Vice President and Head of Power-to-X for Ørsted, commented on the supply chain for hydrogen:
“Ørsted is fully committed to renewable hydrogen as a key solution to defossilise hard-to-electrify sectors such as aviation. Our long experience in developing and deploying new technologies has taught us that collaboration across policymakers, developers, customers and supply chain – and considerable investment from each of them – is critical to bring down costs and drive a new sector to scale. Alliances such as the HIA are essential to bring together different actors across the value chain to support and accelerate the role hydrogen can, and must, play in the UK.”
Why Power Aviation with Hydrogen?
Hydrogen’s promise as an aviation fuel primarily lies in its clean emissions. Unlike conventional fuels, burning hydrogen only releases water vapor, making it an attractive alternative to meet net-zero emission targets. Furthermore, the UK aviation industry, contributing over £22bn directly to the GDP, plays a pivotal role in the nation’s economy. A transition to hydrogen secures the aviation industry’s future, safeguarding the 230,000 jobs it provides.
Public Perception and Support for Hydrogen-Powered Flights
Recent research by HIA founding member easyJet reveals:
- 81% of the British public believe hydrogen to be the best solution for decarbonizing aviation.
- 91% support the UK government’s investment in hydrogen production and its use in aviation.
- 89% feel that sectors challenging to decarbonize, like aviation, should prioritize hydrogen.
The UK populace understands the importance of aviation for the economy, with 92% recognizing the job opportunities that investments in zero-carbon sectors can create. A promising 87% are excited about a sustainable energy economy’s economic potential.
- The Jet Zero council projects the UK’s potential share in the global aerospace industry at 19% by 2050, translating to around £34bn annually for the UK.

- More about the UK government’s vision for a hydrogen economy.
- 3gem conducted consumer research among 2,000 UK households in August 2023.
