ABSTRACT:
A liquid hydrogen storage system having minimized tanking losses. Hydrogen is discharged from a liquid hydrogen tank through connector piping of a filling connector to a discharge pipe and then to an external device, such as a fuel cell. As such, the connector piping is maintained at a cryogenic temperature substantially that of liquid hydrogen. During refilling of the tank through the already cryogenically cold connector piping there is substantially reduced evaporation of the liquid hydrogen provided by a liquid hydrogen tank station.
