ZeroAvia is developing hydrogen-electric powertrains targeting zero-emission regional flights up to 500 miles, with commercial operations projected for 2028–2029.
VectorThe Eviation Alice flew in 2022, but turning an 820 kWh battery-electric commuter into a certified airline product still requires years of unglamorous work.
VectorZeroAvia's hydrogen fuel cell Dornier 228 has already flown, targeting a regional turboprop market that battery-electric aircraft physically cannot serve.
VectorZeroAvia's hydrogen-electric Dornier 228 flight in January 2023 marked the first time a 19-seat regional airframe flew on hydrogen fuel cell propulsion, reshaping the math on zero-emission regional aviation.
VectorHeart Aerospace's 25,000-pound Heart X1 became the largest battery-electric airplane ever flown - here's what it proves and what it doesn't.
TowerElectra's hybrid-electric EL9 uses blown lift and eight electric motors to take off and land in as little as 150 feet.
VectorZeroAvia is betting hydrogen fuel cells, not batteries, will electrify regional aircraft - here's why the physics works and what still stands in the way.
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 fuel cells aim to power regional aircraft where batteries can't reach - and the real hurdles that remain.

VectorElectra's hybrid-electric EL9 uses blown lift to take off and land in 150 feet, aiming to replace helicopters on short regional routes.
VectorHow Beta Technologies built an electric airplane and the CCS charging network it needs - and why the plain fixed-wing came first.
VectorHow ZeroAvia's hydrogen-electric Dornier 228 flight proved fuel-cell propulsion can power real regional aircraft - and the hurdles that remain.
VectorRadio Hangar explores Eviation Alice, the All-Electric Nine-Seat Commuter, and the Battery Math That Decides Whether a Clean-Sheet Electric Airliner Ever Earns Its Wings.
VectorEviation's all-electric Alice flew in 2022, but battery physics - not motors - will decide if it ever carries paying passengers.
VectorThe FAA has cleared Heart Aerospace's Heart X1 electric demonstrator for flight testing in upstate New York ahead of its first flight.
TowerLoganair ordered up to 10 Beta Alia CX300 electric aircraft, aiming to fly Europe's first all-electric commercial fleet.
TowerZeroAvia's hydrogen fuel cell powertrain program is the most documented attempt to overcome the 300-nautical-mile range ceiling that battery electric aviation cannot break.
VectorElectra Aero is engineering a hybrid eSTOL aircraft using blown lift technology targeting 150-foot ground rolls, with a credible path to restoring air service to thousands of underserved communities.
VectorZeroAvia flew a hydrogen fuel cell-powered Dornier 228 in January 2023, marking the most significant step yet toward zero-emission regional aviation.
