Liquid Dispensing

liquid to liquid

Hydrogen liquid is denser than hydrogen gas. Fueling stations that can dispense hydrogen as a liquid hydrogen promises faster refueling times and reduced fueling station costs.  Within this space, subcooled liquid hydrogen (sLH2) is showing promise. This method uses a modest increase in storage pressure (1.6 MPa) to increase the hydrogen boiling temperature, resulting in a more stabilize liquid. Hydrogen storage vessels do not need carbon fiber reinforcement, and compressors and chillers are eliminated. With fewer components, the station design is simplified resulting in reduced cost. ​
