ZeroAvia and KLM Royal Dutch Airlines have announced a collaboration to work towards a joint demonstration flight utilizing ZeroAvia’s ZA2000 hydrogen-electric engines for large regional turboprop aircraft. The hydrogen-electric engines function by using hydrogen in fuel cells to generate electricity for powering electric motors that drive the aircraft's propellers, resulting in only low-temperature water vapor emissions. This technology is expected to reduce climate impact by up to 90% compared to conventional kerosene-fueled flights. The companies have set a milestone to conduct an A-to-B flight demonstration between two airport locations in 2026. They are currently focused on securing regulatory permits, ensuring the availability of liquid hydrogen fuel, and establishing the necessary infrastructure for aircraft fueling. This partnership aims to provide evidence for cleaner flight adoption within KLM's network and accelerate the development of hydrogen-powered aircraft concepts across the European Union. KLM emphasizes its commitment to sustainability by supporting advanced technologies like hydrogen and electric aviation as part of its strategy to decarbonize the aviation industry. The airline's maintenance divisions are already collaborating with ZeroAvia to develop efficient MRO (Maintenance, Repair, and Overhaul) operations for hydrogen fuel cell planes. ZeroAvia has conducted extensive testing of its ZA600-engine prototype and key technologies for the ZA2000 system, including cryogenic tanks for liquid hydrogen and proprietary fuel cell and electric propulsion systems. The ZA2000 system is designed to support regional turboprop aircraft with up to 80 seats. Overall, this collaboration between ZeroAvia and KLM represents a significant step towards achieving a more sustainable future in aviation through the adoption of hydrogen-electric propulsion systems.
