The Netherlands’ aerospace research organization has launched a project to convert a Pipistrel Velis Electro to use a hydrogen fuel cell propulsion system.
Netherlands Aerospace Centre (NLR) will work with fuel cell company Zepp.solutions to develop and integrate the system on to the Velis Electro, with a first demonstration flight planned for 2026.
Netherlands-based company Zepp, which was spun out of TU Delft in 2017 supplies hydrogen fuel cell systems for large off-highway vehicles, trucks, marine applications and motorsport.
The agreement between NLR and Zepp will help the latter to develop fuel cell systems for aviation by demonstrating and further developing its technology in the aviation sector.
Arjen Kloosterman, the NLR project leader said, “‘We aim to use this project to gain knowledge and experience in the development and integration of hydrogen components and powertrains for manned aviation. Besides physical integration, the biggest challenges are the airworthiness and safety aspects associated with introducing hydrogen onboard an aircraft.
“The entire trajectory up to the demo flight in 2026 provides us with valuable knowledge and insights for hydrogen technology integration and is thus a prelude to further developments and implementation of this technology in the aviation sector. Collaborating with Zepp is an essential step for us and will significantly contribute to NLR’s Climate Neutral Aviation program.”
Jan Bot, co-founder of Zepp.solutions said, “Our fuel cell technology has already proven itself in various sectors. We bring a lot of knowledge and experience in developing efficient and compact fuel cell systems.
“However, aviation offers completely different challenges. This cooperation, and learning from each other in this way, is therefore incredibly valuable. In developing the hydrogen system for the Pipistrel, together with NLR, we will not only demonstrate the potential of hydrogen in aviation but also learn lessons that can be of great value to this sector.”
