ZeroAvia announced a development collaboration with Alaska Air Group, the parent company of Alaska Airlines, for a hydrogen-electric powertrain capable of flying 76-seat regional aircraft in excess of 500 NM. Alaska is also joining the list of top investors for the company, alongside a fellow Seattle-based Amazon Climate Pledge Fund and Bill Gates'sBreakthrough Energy Ventures. Alaska and ZeroAvia engineers will work together to scale the company's existing powertrain platform to produce the ZA2000, an engine family capable of producing between 2,000 and 5,000 kilowatts of power with a 500-mile range. The partnership will initially deploy ZeroAvia's hydrogen-electric propulsion technology into a full-size De Havilland Q400 aircraft, previously operated by Alaska Air Group subsidiary Horizon Air Industries, Inc., capable of transporting 76 passengers. ZeroAvia will also work closely with aircraft regulators during this project to ensure the aircraft meets both safety and operational requirements. ZeroAvia will set up a location in the Seattle area to support this initiative. Alaska has also secured options for up to 50 kits to begin converting its regional aircraft to hydrogen-electric power through ZeroAvia's zero-emission powertrain, starting with the Q400 aircraft. This pioneering zero-emission aviation rollout will be supported by the ground fuel production and dispensing infrastructure from ZeroAvia and its infrastructure partners, such as Shell. Working to advance novel propulsion is one of the five parts of Alaska's strategy to achieve net zero.
