In a significant move towards sustainable aviation, ZeroAvia has partnered with Horizon Aircraft to potentially create a hydrogen-electric version of the Cavorite X7 eVTOL. This collaboration will involve exploring the integration of ZeroAvia's ZA600 hydrogen fuel cell powertrain into the Cavorite X7, a seven-seater electric vertical takeoff and landing (eVTOL) aircraft currently in development by Horizon Aircraft. Unlike many other eVTOL developers, Horizon Aircraft had initially planned a hybrid propulsion system for the Cavorite X7, combining batteries with a conventional gas-powered engine to enhance range and performance. The Cavorite X7 is designed to achieve a range of 500 miles and a cruising speed of up to 250 knots, incorporating electric lift fans for vertical flight and a rear-mounted propeller for horizontal travel. By considering a hydrogen-electric option, Horizon Aircraft is aligning with the emerging trend of hydrogen propulsion in aviation, similar to Joby Aviation's endeavors in the field. Horizon Aircraft has demonstrated progress in flight testing, successfully conducting untethered flights of a scaled model of the Cavorite X7 and completing a transition from vertical to horizontal flight in May 2025.
