Abstract: The invention relates to a system for storing liquid hydrogen and for distributing gaseous hydrogen, comprising a source of liquid hydrogen (20), at least two gaseous hydrogen tanks (31-35) to be filled and a transfer device comprising: a transfer unit (25) configured to transfer liquid hydrogen from the hydrogen source (20) to any of the tanks, a vapour compressor (10) having a first upstream end and a second downstream end fluidly connected to each of the tanks, a set of valves (51-55), a control device configured to issue a command to transfer the liquid hydrogen and to open and/or close one or more valves (51-55), the compressor (10) being arranged so as to transfer vapours created during filling from any tank to each of the other tanks in succession, by compressing the vapors to a pressure greater than the pressure in the tank during filling.

Abstract: The invention relates to a method for pressurising gaseous hydrogen comprising the following steps: providing a first tank (1) capable of receiving pressurised gaseous hydrogen, filling the first tank (1) with compressed gaseous hydrogen at a first pressure, cooling the compressed gaseous hydrogen contained in the first tank (1) to a first cryogenic temperature, transferring, by means of pressure equalisation, one portion of the gaseous hydrogen at the first cryogenic temperature from the first tank (1) to at least one second tank (2), sealing the at least one second tank containing the hydrogen transferred from the first tank, increasing the pressure in the second tank by heating the hydrogen present in the second tank to a second temperature higher than the first temperature.
