Schiphol Airport in the Netherlands is set to conduct the first test of a hydrogen-powered ground power unit (GPU) in collaboration with zepp.solutions and Dynell. This innovative initiative aims to provide emissions-free power to stationary aircraft during ground operations. The hydrogen GPU offers the advantage of on-site refuelling, eliminating the need to move to charging points for recharging, unlike electric GPUs currently in use. Furthermore, it is reported to support larger capacities similar to diesel GPUs. The use of green hydrogen, produced without CO2 emissions using solar and wind energy, adds to the sustainability aspect of the project. The European Union is co-funding this test as part of the TULIPS partnership, which includes 29 aviation parties led by the Royal Schiphol Group, with the goal of transforming aviation operations to be more environmentally friendly. In a related development, Airbus, easyjet, and Air Products have joined forces to explore the introduction of hydrogen infrastructure at London Gatwick Airport, focusing on aspects like liquid hydrogen supply and storage, refuelling, and ground handling of hydrogen aircraft. These collaborations signify a growing momentum in the aviation industry towards adopting hydrogen as a clean energy source for future operations.
