ZeroAvia and KLM Royal Dutch Airlines have announced a partnership to work on a demonstration flight using ZeroAvia's ZA2000 zero-emission, hydrogen-electric engines for large regional turboprop aircraft. These engines use hydrogen in fuel cells to generate electricity, powering electric motors and propellers with only low-temperature water vapor emissions. The collaboration aims for up to a 90% reduction in climate impact compared to traditional kerosene-fueled flights. The companies plan to conduct an A-to-B flight demonstration in 2026, focusing on regulatory permits, liquid hydrogen fuel supply, and infrastructure development. KLM expresses its commitment to sustainability and innovation in aviation, supporting technologies like electric, hydrogen, and hybrid-powered flights to drive industry change and lead towards a more sustainable future. ZeroAvia has already conducted tests for its ZA600-engine prototype and key technologies for the ZA2000 system, capable of supporting up to 80-seat regional turboprop aircraft for cleaner aviation.
