![]() ![]() Other companies are designing smaller hydrogen aircraft, including retrofits and hydrogen tank-swapping concepts, with demonstrations planned for the near future. ![]() Airbus is also investigating fuel cells, having ordered modular, scalable stacks for testing. Rolls-Royce is also researching hydrogen-powered engines for small aircraft, including narrow-body aircraft. CFM, Airbus, GE and Safran are collaborating on a hydrogen-powered open-rotor engine demonstration programme for larger jets. Together with CFM, Airbus is building a jet turbine capable of combusting hydrogen. However, using hydrogen in aircraft poses a significant set of challenges including the need for innovative fuel storage and delivery methods, low-cost and lightweight cryogenic tanks, and redesigned airframes to accommodate them.Īirbus’s ZEROe is perhaps the most prominent programme, developing large hydrogen aircraft for commercial operation by 2035. ![]() Hydrogen can be used via direct combustion in jet engines, through fuel cells to generate electricity for electric motors, or a combination of both. ![]()
