ZeroAvia and KLM Royal Dutch Airlines have announced a partnership to conduct a demonstration flight using ZeroAvia’s ZA2000 hydrogen-electric engines for large regional turboprop aircraft. These engines generate electricity through hydrogen in fuel cells, powering electric motors to drive the aircraft's propellers, emitting only water vapor and potentially reducing climate impact by 90% compared to traditional kerosene-fueled flights. The companies plan to carry out the initial flight demonstration between two airports in 2026, with tasks including airport selection, regulatory permits, liquid hydrogen fuel supply, and fueling infrastructure establishment. ZeroAvia has already tested its ZA600-engine prototype and conducted advanced ground tests for the ZA2000 system, aiming to support regional turboprop aircraft with up to 80 seats. KLM's Managing Director of KLM Cityhopper, Maarten Koopmans, emphasizes the airline's commitment to innovation for a sustainable future in aviation, supporting various technologies like electric, hydrogen, and hybrid-powered flights. James Peck, Chief Customer Officer of ZeroAvia, expresses excitement about collaborating with KLM and the aviation industry's shift towards cleaner, hydrogen-electric propulsion, anticipating a positive impact on the sector's environmental footprint.
