ZeroAvia has confirmed that its new liquid hydrogen (LH₂) facility at Cotswold Airport is fully prepared to support the upcoming phase of hydrogen flight testing. This development comes after the company recently moved its Dornier Do228 test aircraft to the site, where final preparations are underway ahead of a new series of trials.
The upgraded infrastructure now allows the testbed aircraft to be safely and efficiently refuelled with liquid hydrogen, a key milestone as ZeroAvia moves closer to demonstrating real operational capabilities. In addition to aircraft refuelling, the facility will be used to assess hydrogen fuel cell systems and related components on the ground, helping to refine performance, reliability and handling under test conditions.
A specialised cryogenic system—including advanced liquid hydrogen storage and handling equipment—has been installed at the site, designed to minimise hydrogen loss and ensure safe, consistent fuel delivery. This capability supports both high-fidelity data collection and ongoing development work.
By establishing this dedicated testing hub at Cotswold Airport, ZeroAvia is advancing its broader strategy of maturing hydrogen-powered aviation technology from prototype stage towards certification and eventual commercial use. The facility will play a key role in validating propulsion systems, refuelling processes, and operational procedures under real-world conditions as the company continues its journey toward zero-emission flight.
