The ZA600 is a 600kW hydrogen-electric powertrain and the first commercial product from ZeroAvia. It will deliver zero-emission flight for thousands of 9–19 seat regional turboprops, beginning with the Cessna Grand Caravan, which will receive supplemental type certification for retrofit and linefit of this popular airframe.

The first ZA600 equipped commuter platform will be ready for service in 2025, fueled by gaseous hydrogen tanks and capable of carrying passengers up to 250 NM plus reserves. With an agreement in place with OEM Textron Aviation, ZeroAvia is well advanced in bringing a certified product for zero-emission propulsion to market within the next three years.

True Zero-Emission Flight and Fuel

Aviation’s climate impact is projected to be more in focus as demand grows and other sectors decarbonize. The time to act is now, but many operators of small aircraft like the Cessna Caravan have limited options for reducing emissions footprints without new platforms.

By bringing cutting-edge fuel cell and electric motor technology together — the ZA600, ZeroAvia’s industry leading hydrogen-electric powertrain, can deliver an option for retrofitting aircraft to enable emission-free flight while also slashing operating costs. The result? An unparalleled aircraft engine that will deliver improved operating economics without harming the planet.
