The Netherlands Aerospace Centre (NLR) has initiated a project in partnership with fuel cell company Zepp.solutions to convert a Pipistrel Velis Electro aircraft to operate using a hydrogen fuel cell propulsion system. This collaboration aims to develop and integrate hydrogen components and powertrains for manned aviation, with a demonstration flight scheduled for 2026. NLR's project leader, Arjen Kloosterman, highlighted the significance of gaining knowledge and experience in hydrogen technology integration, emphasizing the challenges related to airworthiness and safety in incorporating hydrogen aboard aircraft. The cooperation with Zepp.solutions is crucial for NLR's Climate Neutral Aviation program and the advancement of hydrogen systems in aviation. Jan Bot, co-founder of Zepp.solutions, expressed the value of learning from the different challenges presented by aviation and the potential benefits for the sector. This initiative not only showcases the potential of hydrogen in aviation but also underscores the importance of collaboration and innovation in driving sustainable solutions for the industry.
