Hydrogen-Electric Propulsion System

Our patent-pending fuel cell technology is 6x lighter than the current state of the art, unlocking hydrogen-electric aircraft that can fly 10x further than battery-electric alternatives and are 50% cheaper to operate than fossil fuel-powered aircraft. Our HEPS can also power long-range drones or heavy-duty vehicles.

15-seat Retrofit Aircraft

Our 15-seat Beechcraft 1900D-HE aircraft is a hydrogen-electric retrofit solution that is gaining traction with airlines as a near-term solution with minimal refuelling infrastructure impact. It will outperform current 19-seat conventional turboprops on cost per available seat (CASK) while meeting zero-emission targets.

50-seat Clean Sheet Design

The Stralis SA-1-HE is the world’s first 50-seat aircraft optimised for hydrogen-electric technology. Designed to fly 3000km it will achieve ~50% lower operating costs than comparable aircraft. It has been designed to meet the demand for profitable decarbonised travel at scale and to provide a world-class passenger experience.
