In the Netherlands, a partnership between fuel cell specialist zepp.solutions and the Dutch Aerospace Centre NLR aims to develop a new fuel cell system for a manned flight with liquid hydrogen by 2026. The collaboration seeks to convert the Pipistrel Velis Electro research aircraft to run on liquid hydrogen, with zepp.solutions tasked with integrating the fuel cell system into the aircraft. The project is part of the NLR's ambition to conduct a demo flight in 2026, as a key pillar in advancing sustainable aviation within the Dutch ecosystem. The collaboration focuses on gaining knowledge and experience in developing and integrating hydrogen components for manned aviation, with a strong emphasis on airworthiness and safety aspects associated with introducing hydrogen onboard an aircraft. The project, co-funded by the Dutch government's National Growth Fund, aligns with NLR's Climate Neutral Aviation programme, aiming to make aviation climate-neutral by 2050. This initiative represents a significant step towards the integration of hydrogen technology in the aviation sector, with potential lessons that could benefit the industry as a whole.
