The Clean Future of Flight Starts Here
World-first hydrogen-electric powertrain to slash emissions and operating costs

Utilizing ZA600 powertrains in 10-20 seat aircraft can enable:
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.
