The UK's first hydrogen aircraft trial turnaround took place at Exeter Airport, featuring a TUI Boeing 737 aircraft and hydrogen-powered ground equipment. The trial was supported by the UK Civil Aviation Authority’s Hydrogen Challenge program, Cranfield University, ULEMCo, MULAG, and Boeing. The equipment, including a baggage tug, pushback tug, and ground power unit, was refueled using green hydrogen produced by Protium. Exeter Airport's Managing Director highlighted the importance of sustainability and innovation in hosting such trials. Studies by Cranfield University revealed significant diesel consumption and emissions from airport operations, with ground power units being a major source of emissions. The Hydrogen Challenge program, funded to support the Government's Jet Zero targets, aims to develop and test hydrogen technologies. Science Minister Lord Vallance emphasized the need for fresh thinking and regulatory support to accelerate innovation in the UK. ULEMCo's Managing Director praised the versatility and cost-effectiveness of hydrogen fuel, advocating for increased investment in UK-wide refueling infrastructure. Such trials and studies are vital in advancing regulations and understanding airside hydrogen use, potentially paving the way for hydrogen-fueled aircraft in the future.
