HORIZON-JU-CLEAN-AVIATION-2026-04-HPA-01 - Demonstration of advanced FC propulsion techno-bricks for a fully electric hydrogen fuel cell powered aircraft

Expected Outcome:Development and demonstration of the critical components and sub-systems of a hydrogen fuel cell engine for the fully electric hydrogen fuel cell powered aircraft concept. This project will deliver and demonstrate the components and sub-systems on ground at TRL5, for a lightweight, compact and efficient fuel cell engine, demonstrated at TRL4 thus enabling a viable hydrogen fuel cell powered aircraft concept. See the topic description document published with this call for full details.
