ZeroAvia announces HyPRIME to demonstrate liquid-hydrogen refuelling and integrated ground systems for commercial aviation

ZeroAvia is leading HyPRIME, a Department for Transport–supported project to develop and demonstrate liquid-hydrogen refuelling infrastructure, ground support equipment integration, and operational procedures for future LH₂-powered commercial aircraft. The live-airport demonstration will evaluate safety, economics, boil-off capture, Helium-free inerting, and the ability to refuel within standard commercial turnaround times to enable zero-emission airport operations.
