The UK Civil Aviation Authority (CAA) has opened applications for a new phase of its Hydrogen Challenge programme, inviting organisations to participate in research and testing for the future use of hydrogen in aviation.
The initiative forms part of the regulator’s Regulatory Sandbox programme, which allows companies, academic institutions and other organisations to explore emerging aviation technologies in collaboration with regulators.
The latest round of applications will focus on hydrogen-powered aviation technologies, airport infrastructure, advanced electric motors and the potential role of artificial intelligence in supporting the safe adoption of hydrogen-based systems.
The programme is intended to improve understanding of the opportunities and challenges associated with hydrogen as a potential aviation fuel. Areas under examination include operational safety, infrastructure requirements, regulatory considerations and the broader integration of hydrogen technologies into airports and aircraft.
Hydrogen is a possible alternative to conventional aviation fuels. Supporters argue that it could contribute to efforts to reduce carbon emissions from air transport while also helping to diversify future energy sources.
The Hydrogen Challenge forms part of wider work across the aviation sector to support the UK’s target of reaching net zero greenhouse gas emissions by 2050. The programme seeks to identify potential regulatory gaps and safety requirements before hydrogen technologies are deployed on a larger scale.
Sophie O'Sullivan, Director of Future Safety and Innovation at the UK Civil Aviation Authority, said:Hydrogen has the potential to transform aviation.
Through the Hydrogen Challenge, we are working closely with some of the top innovators in the UK to advance hydrogen technology, deepen our understanding of its impact and ensuring it is developed safely.
These early steps put us on the path to a sustainable future for flying.
Previous participants in the Hydrogen Challenge have included aviation company ZeroAvia and the Exeter Airport Consortium. The consortium previously completed a hydrogen-powered live aircraft turnaround, which involved ground operations using hydrogen technology at an airport environment.
The new application round is intended to encourage further collaboration between regulators, researchers and industry as work continues to assess the viability and safety of hydrogen-powered aviation in the UK.
