ZeroAvia, a developer of hydrogen-electric propulsion systems, has made a significant step in the aviation industry by selling its 600-kW electric propulsion system to Jetcruzer International. This partnership aims to test the electric-powered version of the Jetcruzer 500 and further develop hydrogen-electric aircraft derivatives. ZeroAvia's decision to offer electric propulsion components to other customers is aligned with its ongoing work on the ZA600 powertrain for aircraft retrofitting. The establishment of a propulsion center of excellence in Everett, Washington, marks a strategic move to produce electric propulsion systems for internal and external clients. Jetcruzer International, known for resurrecting the AASI Jetcruzer, plans to electrify one of its aircraft with ZeroAvia's electric motor and aims to introduce the hydrogen-electric Jetcruzer 500E by 2028. The collaborative effort also includes the development of the Jetcruzer 1250E, featuring hydrogen fuel cells and twin pusher propellers, set for entry into service in 2030. This partnership is a significant leap towards the advancement of innovative and eco-friendly aviation technology.
