ZeroAvia flies a Dornier 228 with a hydrogen-electric engine on one wing

ZeroAvia/ZA600

ZeroAvia flew its 19-seat Dornier 228 testbed from Cotswold Airport in Gloucestershire with a 600kW hydrogen-electric powertrain on the left wing while retaining a stock turboprop on the right for comparison. The 10-minute flight marked the first crewed flight of the largest aircraft to fly on hydrogen-electric power, part of the UK-backed HyFlyer II project toward commercial certification.
