Claim 13:
14. An installation for the storage and distribution of liquefied hydrogen:
comprising a liquid hydrogen storage facility at a specific storage pressure;
a source of gaseous hydrogen;
a liquefier comprising an inlet fluidly connected to the source and an outlet fluidly connected to the liquid hydrogen storage facility, wherein the liquefier is configured to produce liquid hydrogen and to feed the storage facility with liquid hydrogen at a temperature below the bubble point of hydrogen at the storage pressure;
a liquid withdrawal pipe comprising an end connected to the liquid hydrogen storage facility and at least one other end configured to be connected to a mobile liquid hydrogen tank,
a boil-off gas recovery pipe comprising a first end configured to be connected to the mobile liquid hydrogen tank and a second end configured to be connected to the storage facility;
a transfer pipe having a first end connected to the outlet of the liquefier and a second end configured to be connected directly to the mobile liquid hydrogen tank,
the installation being configured to fill the mobile liquid hydrogen tank by transferring a first amount of liquid hydrogen from the liquefier into the liquid hydrogen tank via the transfer pipe and then a second amount of liquid hydrogen from the storage facility to the mobile liquid hydrogen tank via the liquid withdrawal pipe.
