ZeroAvia's hydrogen-electric ZA600 powertrain completed its first flight on a Dornier 228 in January 2023, targeting commuter routes that batteries cannot serve.
VectorZeroAvia flew a hydrogen-electric powertrain in a 19-seat regional turboprop in January 2023 and is targeting commercial certification by 2027.
VectorZeroAvia's hydrogen-electric powertrain has genuinely flown, but volume, cryogenics, and infrastructure make it a late-2020s story at best.
VectorHow ZeroAvia's hydrogen-electric Dornier 228 flight proved fuel-cell propulsion can power real regional aircraft - and the hurdles that remain.
