In a groundbreaking move, Amsterdam Airport Schiphol has initiated pilot tests with a hydrogen-powered ground power unit (GPU) to provide electricity to KLM Cityhopper aircraft on the apron. The hydrogen GPU, a collaboration between Austrian GSE manufacturer Dynell and Dutch company Zepp.solutions, is part of the TULIPS partnership backed by the European Commission. This innovative approach aims to decarbonize airside operations, complementing existing electric equipment. Schiphol's executive director expressed pride in being the first airport to test this innovation, emphasizing the airport's goal of achieving emission-free ground activities by 2030. The new hydrogen GPU can be refueled on site, saving time compared to electric GPUs that require charging at specific points. The TULIPS project, involving various European aviation entities, is focused on developing sustainable technologies for airport operations, including sustainable aviation fuel deliveries and circular material solutions. This successful collaboration highlights the aviation industry's commitment to cleaner alternatives and aligns with the EU Green Deal's objectives.
