Exeter Airport in the United Kingdom recently made history by hosting the country's first hydrogen-powered live aircraft turnaround. In partnership with TUI, Cranfield University, ULEMCo, MULAG, and Boeing, the demonstration exhibited how hydrogen can play a crucial role in reducing carbon emissions in airport ground operations. The trial, supported by the UK Civil Aviation Authority's Hydrogen Challenge program, featured a TUI Boeing 737 undergoing a turnaround with ground support equipment fueled by green hydrogen. This initiative marked the first instance in the UK where multiple hydrogen-powered equipment pieces were utilized simultaneously for commercial air transport operations, emphasizing the utilization of 'green' hydrogen sourced from renewable energy. Stephen Wiltshire, Exeter Airport's managing director, expressed pride in hosting the trial, emphasizing its significance in promoting sustainability and innovation. The trial is part of the CAA's broader Hydrogen Challenge program, aimed at facilitating the early adoption of low- and zero-emission aviation technology to align with the government's Jet Zero ambitions. With a comprehensive study revealing the substantial CO2 emissions from diesel fuel consumption in ground handling operations, the trial at Exeter Airport employed retrofitted vehicles with various hydrogen technologies, showcasing the versatility and potential of hydrogen as a clean fuel. The successful demonstration received positive feedback from industry experts like Giancarlo Buono, highlighting the progress made towards establishing hydrogen as a safe and viable energy source for aviation. Amanda Lyne of ULEMCo emphasized the growing case for investing in UK-wide refueling infrastructure as real-world applications of hydrogen fuel increase.
