The Dewar is maintained by Cryoworld and can provide clients with a safe and reliable way to store and handle LH2, supporting a range of research, development, and testing activities related to hydrogen technology.
Due to its extremely high energy density per kilogram (120MJ/kg), hydrogen is a potential contender for alternative aviation fuel. However, hydrogen is a buoyant gas that needs to be compressed into high pressure tanks (300-700 bar) or stored on board an aircraft in liquid form in a cryotank at an extremely low temperature (-253°C, 1 bar).
NLR offers:
- Safe storage and handling of LH2
- Support for research and development
- Preparation for drone test flights
- Ground testing of hydrogen systems
- Fueling activities
