ZeroAvia has secured two 19-seat Dornier 228 turboprops for the next phase of its hydrogen-electric-powered aircraft development efforts, the company said on Tuesday. The company plans to replace the aircraft’s twin engines with two 600 kW electric powertrain units and hydrogen fuel tanks eventually holding 100 kg (220 pounds) of compressed gaseous hydrogen to support a projected 500-mile range. The tanks will be mounted on the wings of the aircraft.

The California-based company said its work is progressing on the software, hardware, mechanical integration, and fuel cell balance-of-plant to the certifiable state. It expects to gain certification in 2024, clearing the way for the aircraft to start regional airline services.
