    Utilizing ZA600 powertrains in 10-20 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 ZA600 is a 600kW continuous hydrogen-electric powertrain for fixed-wing platforms

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

    Fueled by gaseous hydrogen tanks and capable of carrying passengers up to 300 NM.

    How do hydrogen-electric powertrains 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

    Gaseous 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

    The Hydrogen-Electric Cessna Grand Caravan White Paper

    Learn more about how ZeroAvia’s 600kW, ZA600 engine can support the Cessna Grand Caravan. The White Paper includes a technical overview, route analysis, and information on emissions savings, operating cost savings, retrofit and maintenance. We also explore hydrogen fuel production and airport refueling.

    News on ZeroAvia Flight Testing Program

    We have retrofit our prototype ZA600 engine to power the left side propeller of our Dornier 228. We’ll use this page to share the latest updates from the flight test program, including photos and videos from flights, as well as behind the scenes content.
