Exeter Airport in the United Kingdom has made a significant stride in sustainability by conducting a groundbreaking trial, replacing traditional diesel-powered ground vehicles with hydrogen alternatives for aircraft turnaround operations. The trial involved servicing a TUI Boeing 737 with hydrogen-powered equipment including a baggage tug, pushback tug, and ground power unit. These units were fueled by hydrogen sourced from renewable sources, provided by Fuel Cell Systems through a mobile refuelling unit. The initiative aimed to reduce the airport's carbon footprint, which had previously amounted to 78,000 litres of diesel and nearly 200 tonnes of carbon emissions annually. The successful demonstration not only showcased the feasibility of integrating hydrogen into daily airport operations but also highlighted the potential for significant emission reductions in the aviation sector. Data collected from this trial will play a vital role in establishing safety standards for hydrogen implementation in airport ground operations and shaping long-term strategies to combat emissions in the aviation industry. The collaboration under the Civil Aviation Authority's Hydrogen Challenge program, involving TUI, Cranfield University, Boeing, ULEMCo, and MULAG, underscores the collective effort toward harnessing hydrogen technology for a more sustainable aviation sector. This initiative aligns with a broader industry push, with key players like Airbus aiming to introduce hydrogen-powered passenger aircraft by 2035. While some airlines have embraced this shift, with calls for the UK Government to accelerate the strategy for integrating hydrogen-powered aircraft, others like Wizz Air have chosen not to include hydrogen in their sustainability plans.
