The European Union Aviation Safety Agency (EASA) recently organized its first international workshop in Cologne, Germany, centered on certifying aircraft powered by hydrogen. The event brought together more than 100 representatives from various sectors of the hydrogen community, including fuel cell companies, academics, research institutes, startups, and established companies. International entities such as the UK's Civil Aviation Authority (CAA), the US Federal Aviation Administration (FAA), and the Japan Civil Aviation Bureau (JCAB) were also present at the workshop. Discussions during the workshop highlighted the importance of focusing on technology application in aviation, particularly in areas like hydrogen storage and airworthiness considerations related to preventing fire and explosions. Despite the consensus on the need to maintain current safety standards, participants emphasized the necessity of technology maturation before engaging authorities effectively. Additionally, the workshop addressed the roles of operators in the certification process and identified the optimal strategies for involving them. Overall, the sentiment of the workshop was positive, emphasizing collaboration and advancement in certifying hydrogen-powered aircraft.
