Alaska Airlines in Zeroavia hydrogen retrofit deal

Seattle-based Alaska Airlines is partnering with US-UK hydrogen-electric aircraft developer Zeroavia to retrofit its fleet of 76-seat De Havilland Q400 short-haul aircraft with a hydrogen-electric powertrain. Alaska Air’s Seattle hub will act as the starting point for the transition, as the joint venture will need to construct onsite hydrogen production and develop a hydrogen refuelling network to serve an initial round of flight destinations.
