A priority for the Stade ZEDC is the development of cost-competitive lightweight Hydrogen systems such as cryogenic Hydrogen tanks, in composites.
The A380 will have four liquid hydrogen tanks in a caudal position, as well as a hydrogen combustion engine mounted along the rear fuselage. The hydrogen will be transformed into gas before supply to the engine.
A trans-continental airliner, a regional turboprop and a blended-wing airliner are all powered by hydrogen. Airbus aims to have one of them in service by 2035, although airport infrastructure will need huge investment.
