Innovative light weight and reliable liquid hydrogen tank
Funds a research project that develops and demonstrates a lightweight, reliable liquid hydrogen tank for hydrogen-powered aircraft.
This single-stage Innovation Action is the fourth call for proposals (CfP 04) run by the Clean Aviation Joint Undertaking, opening 31 March 2026 and closing 19 May 2026. One grant of up to EUR 5,000,000 is expected from this topic; the EUR 329,500,000 figure shown against it on the Portal is the shared financial envelope for all 18 topics in the same call, not this topic's own pool. Two rounds of …
This call funds work on a new hydrogen tank design, built to be light and dependable enough to fit inside aircraft that run on liquid hydrogen. Proposals should reach Technology Readiness Level 4 with a gravimetric index of at least 40% and a dormancy of at least 12 hours, proven through on-ground cryogenic and tightness testing.
