Dovetail Electric Aviation has unveiled the 600-kilowatt hydrogen-electric powerplant it intends to use to convert existing passenger and freight aircraft. The Australia-based start-up announced that it had started ground testing the propulsion system during an open day event held in Seville, Spain, on July 17.

According to CEO and co-founder David Doral, the tests have involved replicating the engine bay of a Beechcraft King Air aircraft in terms of internal space and nacelle geometry. The system includes a propeller, an electric motor with a governor, fuel cells, gaseous hydrogen storage units, inverters, a power distribution unit, integrated ducts, and a heat exchanger, as well as the company’s proprietary battery system.
