Heart Aerospace develops hybrid-electric regional aircraft to electrify short-haul commercial flights, backed by United Airlines, Mesa Air, and Bill Gates.
Heart Aerospace is a Swedish electric aviation company founded in 2018 that is developing the ES-30, a hybrid-electric regional aircraft designed to carry 30 passengers on routes up to 400 kilometers. The company is targeting the regional aviation segment where short routes and lower utilization requirements make electric propulsion more economically viable than long-haul jet operations. Heart raised over $100M with backing from United Airlines Ventures, Mesa Air Group, and Breakthrough Energy Ventures, which is funded by Bill Gates. The ES-30 uses a hybrid-electric powertrain with electric motors for takeoff and climb and turbine generators for cruise, allowing the aircraft to operate on existing airport infrastructure while achieving significant emissions reductions compared to conventional turboprop aircraft. Heart is targeting EASA and FAA type certification and has a memorandum of understanding for orders from regional airline partners. The company is based in Gothenburg, Sweden and leverages the European aviation regulatory environment and government support for green aviation technology development.
