Components Development and Experimental Testing for an Onboard Liquid Hydrogen Supply and Conditioning System in High-Power Fuel Cell Aviation Applications
Funds research into onboard components for a liquid hydrogen supply system for fuel cell aircraft, run in tandem with a matching Clean Aviation project.
The selected project has to build directly on earlier Clean Hydrogen JU work -- named projects ELVHYS, HEAVEN, BRAVA and COCOLIH2T -- and draw on findings from four Clean Aviation JU projects researching liquid hydrogen and fuel cell propulsion. Development of the cryogenic storage tank itself and of the fuel cell system sits outside this topic's scope entirely; only the supply and conditioning ha…
This call funds specific hardware — piping, valves, sensors, control units — that feeds cryogenically stored hydrogen from an aircraft's tank to its fuel cells, aimed at high-power aviation use. It does not cover the overall system architecture or the pump and heat exchanger design: those are funded separately under the Clean Aviation JU's own topic HORIZON-JU-CLEAN-AVIATION-2026-04-HPA-02, and the two projects are required to run in parallel and share results.
