Energy to Propulsion Test Facility (EPTF)

The urgent need to achieve emission-free flight by 2050 necessitates the development of sustainable propulsion technologies, with hydrogen-electric flight as a promising candidate. To ensure reliability and safety, comprehensive testing of components and the full powertrain is crucial, which is precisely the purpose of NLR’s “Energy to Propulsion Test Facility” (EPTF). By facilitating these tests, the EPTF will help accelerate the development of this groundbreaking technology.

We offer a state-of-the-art testing facility for comprehensive (ground) testing and expert support to help you develop and improve your hydrogen electric propulsion-related products, whether you’re working on:

  • advanced (composite) storage tanks for holding liquid hydrogen at 20K
  • (3D-printed) heat exchangers to heat gaseous hydrogen
  • (lightweight) compressors for fuel cell or fuselage compression
  • next-generation structural battery packs
  • high-performance megawatt fuel cell systems (without rare earth metals)
  • superconducting or hyperconducting converters and electric motors, including advanced cabling
  • cryogenic liquid hydrogen distributionsystems
  • (silent) propeller systems
