The European Union Aviation Safety Agency (EASA) organized the first International Workshop focusing on certifying aircraft powered by hydrogen. Sustainable Aviation Fuels (SAF) are currently viewed as a significant step in reducing aviation emissions, but alternative fuel sources like hydrogen are essential for long-term sustainability. The event aimed to develop a certification approach supported by the aviation community to ensure high safety standards for future hydrogen-powered aircraft. The workshop gathered over 100 participants from various sectors, including fuel cell companies, academia, and established aviation authorities like the FAA and UK CAA. Discussions emphasized the need for a new certification approach to accommodate the complexity of integrating hydrogen as a fuel, addressing safety concerns and technological interfaces. The lack of in-service experience with hydrogen-powered aircraft poses safety challenges, necessitating a focus on research, technology application, and airworthiness considerations. Industry presentations highlighted ongoing projects on hydrogen storage, fuel distribution, and system integration, underscoring the need for global collaboration to overcome the numerous challenges ahead. The workshop also stressed the importance of maintaining current safety standards and engaging authorities and operators effectively as hydrogen-powered technology matures. Initiatives like Clean Aviation and Alliance for Zero-Emission Aviation are supporting the transition to new technologies, fostering collaboration and knowledge dissemination in the aviation sector. The event featured contributions from various industry leaders and research institutions, reaffirming the commitment to advancing hydrogen-powered aircraft certification in a safe and sustainable manner.
