Hydrogen-Electric Propulsion System for Low-Emission Regional Aircraft

transportTestedTRL 4

Imagine a plane that uses a mix of a traditional engine and a hydrogen-powered electric motor, similar to how a hybrid car works. Instead of relying only on fuel, it uses fuel cells to generate electricity to help push the plane forward. This setup helps the aircraft fly cleaner and use much less fuel during its trip.

The business problem

What needed solving

Regional aviation lacks a viable path to decarbonize quickly because full battery or hydrogen power is not yet mature for 100-seat aircraft. There is a critical need for an intermediate hybrid solution to meet 2035 environmental goals.

The solution

What was built

A design and validation plan for a >2MW parallel hybrid-electric propulsion system, including CDRs for thermal management, fuel cells, and gearboxes.
