ZeroAvia and Hybrid Air Vehicles Collaborate on Zero-Emission Hydrogen Aircraft

ZeroAvia and Hybrid Air Vehicles have partnered to develop a hydrogen-powered version of the Airlander 10, a hybrid aircraft that uses aerostatic lift, aerodynamic lift, and vectored thrust. The partnership aims to achieve an emissions reduction of up to 90% compared to similar capacity aircraft. ZeroAvia’s hydrogen-electric powertrain has already passed regulatory milestones and secured hundreds of pre-orders. The companies will investigate the possibility of equipping the Airlander 10 with four of ZeroAvia’s hydrogen-electric ZA600 powertrains. This development is part of ZeroAvia’s ongoing efforts to commercialize its hydrogen-electric technology, which has already been tested in a Dornier 228 prototype. The partnership was announced on November 10, 2025, and is supported by a €21.4 million EU grant to retrofit 15 Cessna Caravans with hydrogen-electric engines and build supporting airport fuel infrastructure, with operations planned for 2028. RELATED ZeroAvia awarded €21m EU grant to develop hydrogen aircraft network in Norway To date, ZeroAvia has submitted its first complete engine for certification for planes with up to 20 seats and is developing a larger powertrain for aircraft with 40 to 80 seats.
