Absolut Hydrogen's LTG-HRS is a compressor-less liquid-to-gas hydrogen refueling system using thermodynamic compression to supply gaseous hydrogen from liquid hydrogen. The official product page states that the filling station can be adapted to 350 and 700 bar refueling standards while avoiding conventional very-high-pressure compressors. Absolut Hydrogen presents the system as scalable and able to reuse recovered gaseous hydrogen. The solution is intended for hydrogen-mobility infrastructure where liquid hydrogen is available as the source and high-pressure gaseous refueling is required for vehicles or fleet applications.

Use Cases

  • 350 bar hydrogen vehicle refueling
  • 700 bar hydrogen vehicle refueling
  • LH2-fed hydrogen refueling stations
  • Fleet and transport-hub hydrogen infrastructure

Capabilities

  • Converts liquid-hydrogen supply into gaseous hydrogen for vehicle refueling using thermodynamic compression
  • Supports filling-station adaptation to 350 and 700 bar refueling standards
  • Avoids conventional very-high-pressure compressors
  • Supports reuse of recovered gaseous hydrogen
