Clean Aviation Joint Undertaking

Hydrogen powered aircraft concepts and key technologies integration and impact assessment

Funds one team integrating and testing fully electric hydrogen fuel-cell and direct hydrogen combustion aircraft concepts, up to TRL 4.

ClosedClean Aviation Joint UndertakingEU

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 6,000,000 is expected from this topic; the EUR 329,500,000 figure shown against it on the Portal is the shared financial envelope for all 19 topics in the same call, not this topic's own pool. Two rounds of …

The call wants integration and performance assessment of the hydrogen fuel-cell and direct hydrogen combustion aircraft concepts already defined in the Clean Aviation JU's Strategic Research and Innovation Agenda. The work covers coordinating the JU's separate key-technology projects into one aircraft concept and delivering a performance, emissions and maturity assessment at TRL 4.
