UK CAA opens applications for hydrogen aviation research program

June 7, 2026 |

In the UK, Airport Industry Review reported that the UK Civil Aviation Authority (CAA) has opened applications for a new phase of its Hydrogen Challenge program, inviting organizations to participate in research and testing for the future use of hydrogen in aviation.

The initiative forms part of the regulator’s Regulatory Sandbox program, which allows companies, academic institutions and other organizations to explore emerging aviation technologies in collaboration with regulators, according to the report.

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 report added.

The program 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.
