Exeter Airport in the UK is set to lead a pioneering trial involving hydrogen-powered aircraft tug and ground power units to explore decarbonization of ground operations. The trial, conducted under the 'Hydrogen Challenge' initiative involving Exeter Airport, Regional and City Airports (RCA), Cranfield University, and TUI, will focus on testing hydrogen storage, handling, and locally produced hydrogen usage. This three-year stage of the Hydrogen Challenge aims to push forward advancements in hydrogen-powered aircraft, enhance airport infrastructure, and contribute to scientific research. The collaboration intends to conduct flight trials and safety assessments to further develop the technology and its applications. Tim Johnson from the UK Civil Aviation Authority (UKCAA) expressed confidence that these trials will position the UK as a global leader in hydrogen propulsion. Additionally, Exeter Airport will be part of the Hydrogen Challenge Sandbox alongside Rolls-Royce, the University of Oxford, and Cranfield Aerospace Solutions (CAeS), thanks to funding from the UK Department of Science, Innovation, and Technology. Stephen Wiltshire, Managing Director of Exeter Airport, highlighted the trial's significance in showcasing the airport's dedication to innovation and sustainability. This collaboration is expected to provide crucial insights into effectively integrating hydrogen into airport operations, shaping the future of sustainable aviation.
