aerospace research and systems

Battery-electric or hybrid-electric systems for powering aircraft, used alone or in combination with hydrogen.

Hydrogen fuel cells for aircraft convert hydrogen and oxygen into electricity and water on board, producing zero in‑flight carbon emissions at the point of use while powering electric motors for propulsion.[11][14] They are being developed mainly for short‑ to medium‑range aircraft where the lower energy density of compressed or liquefied hydrogen can be offset by efficiency gains and new airframe designs.[11]
