    Utilizing ZA2000 powertrains in 40-80 seat aircraft can enable:

    icon of ZA

    Zero-emission flight and fuel

    Tackling 95% of climate change impact: clean hydrogen in fuel cells generating electricity to power electric motors

    icon of ZA

    Lower and more stable fuel costs

    Green hydrogen cost set to be lower than jet kerosene and SAF; fuel cell systems offer more energy efficient use of fuel

    icon of ZA

    Significantly lower maintenance cost

    ZeroAvia’s hydrogen-electric powertrain promises significant extension of flight hours between major servicing events

    icon of ZA

    Reduced noise and air pollution

    Removing the noise and exhaust of combustion engines to reduce disruption and air quality impacts on communities close to airports

    Green Regional Flight

    The ZA2000 is a 2-5MW modular hydrogen-electric powertrain for up to 80 seat regional turboprops

    Providing efficient, clean and quiet propulsion for the future of regional air mobility

    Fueled by liquid hydrogen tanks and capable of carrying passengers up to 1000 NM.


    How does our hydrogen-electric powertrain work?

    State-of-the-art fuel cell and electric motor technology combine to create an unparalleled aircraft engine with improved operating economics and zero-emissions

    Liquid hydrogen stored onboard in lightweight tanks to feed fuel cell systems and generate electricity

    Electricity used to power electric motors, which turn propulsors to generate thrust
