    Reduce costs and meet emissions reduction targets

    2000+ Engine Pre-Orders from Leading Airlines

    ZeroAvia is bringing to market an electric propulsion system powered by hydrogen fuel cell technology. We are replacing traditional engines on existing and clean sheet fixed wing aircraft.

    Switching to hydrogen-electric propulsion systems will provide operators with:

    Our Products

    We are working with operators to extend the life of existing fleet via retrofit programs or bring new zero-emission aircraft into service via our line-fit agreements with OEMs.

    We are focused on three key product offerings initially



    A 600 kW hydrogen-electric powertrain designed for 10-20 seat aircraft; targeting entry-into-service in 2025



    A 2-5MW hydrogen-electric powertrain designed for 40-80 seat aircraft; targeting entry-into-service by 2027



    A 5+MW hydrogen-electric engine designed to power regional jets up to 1000nm by 2029
