The UK Civil Aviation Authority (CAA) is spearheading an ambitious initiative to explore the potential of hydrogen as a sustainable aviation fuel. This groundbreaking effort, known as the CAA Hydrogen Challenge, seeks to unite industry, academia, and regulators in a collective journey towards a net-zero future.

The Hydrogen Challenge

The Hydrogen Challenge represents a significant step in understanding and harnessing the potential of hydrogen fuel in aviation. It encompasses a Regulatory Sandbox, a unique platform designed to adapt regulation to emerging technologies, mitigate risks, and foster industry-wide collaboration.

For detailed information, visit the CAA Hydrogen Challenge page: CAA Hydrogen Challenge

Collaboration and Insight: The Hydrogen Challenge Survey

In alignment with the Hydrogen Challenge, a comprehensive survey has been launched to gather insights from industry and academia. This survey aims to understand the current state of hydrogen technology, including technology readiness levels, test program dates, and entry into service expectations.

We encourage interested parties to participate in the survey before January 8th, 2024. Your contributions are invaluable in shaping the future of hydrogen in aviation.

The Hydrogen Sandbox

A Testing Ground for Innovation The CAA also invites applications for the Hydrogen Sandbox. This initiative allows stakeholders to work closely with the CAA to test hydrogen technologies and evaluate their compatibility with existing regulations. The Sandbox is open to individual organizations or consortia focused on developing and utilizing hydrogen as an aviation fuel.


The CAA Hydrogen Challenge is more than an initiative; it's a call to action for all stakeholders in the aviation sector. By participating in the survey or applying for the Hydrogen Sandbox, you become part of a pivotal movement shaping the future of sustainable aviation.
