ZeroAvia has announced that its liquid hydrogen (LH₂) facility at Cotswold Airport is now fully prepared to support the next stage of its hydrogen-powered flight testing. The update follows the recent relocation of its Do228 testbed aircraft to the site, where operational readiness is being finalised to begin a new phase of trials focused on high-performance LH₂ systems.
“We now have the capability to safely and efficiently refuel the Do228 with LH2 – a critical step toward real operational readiness,” the company said in a statement, highlighting the site’s role as a dedicated ground and flight-testing hub. The facility will also serve for evaluating small-scale LH₂ fuel cell systems and components, helping to advance reliability and performance metrics critical for commercial certification.
The infrastructure is anchored by Air Liquide’s super vacuum-insulated LH₂ trailer with an LN₂ shield, enabling low boil-off, reduced losses, and consistent fuel handling for high-fidelity data collection.
ZeroAvia’s Cotswold setup forms part of its broader strategy to push liquid hydrogen aviation from prototype to certified platform. With flight testing infrastructure in place, the site is poised to validate not only propulsion hardware but also fuelling logistics, cryogenic handling, and system durability under real-world aviation conditions.
