  • the pump 19 is for example located in the pipe 10 of withdrawal.
  • the liquid hydrogen is injected into the tank 8 and the evaporated liquid returns to the storage 4 via the recovery line 11.
  • the recovered hot fluid is condensed in contact with the hydrogen undercooled contained in the storage 4.
  • This hot fluid can be cooled in the liquid phase via a condenser (optional) or directly by bubbling in the liquid.
  • This forced circulation configuration makes it possible to reduce the filling time of the tank 8.
  • the installation may comprise a pipe 13 having an end connected to the outlet of the liquefier 3 and an end intended to be connected to the (x) tank (s) 8 directly (without passing through the storage 4) cf. FIG. 3.
  • the pipe 13 may be provided with a valve 20 (preferably controlled) for transferring liquid hydrogen from the liquefier 3 to the tank 8.
  • the hot fluid recovered by the recovery pipe 11 is returned to storage 4 to be cooled / condensed.
  • This configuration advantageously makes it possible to fill reservoirs 8 with sub-cooled hydrogen at a pressure greater than the maximum operating pressure of the reservoir 4, without using a pump.
  • the installation may comprise a pipe 13 having an end connected to the outlet of the liquefier 3 and an end intended to be connected directly to the (x) tank (s) 8 to be filled (without passing through the storage 4).
  • the pipe 13 can be provided with a valve 20 (preferably controlled) for transferring liquid hydrogen from the liquefier 3 to the tank 8.
  • the hot fluid present in the tank 8 is kept in the tank 8 by closing the valve 21 on the pipe 11 back to storage 4 until the pressure in the tank 8 has dropped sufficiently (up to a determined pressure level) due to the condensation of hot vapors by the liquid hydrogen under As previously, the hot fluid can then be recovered by the recovery line 11 and then returned to the storage 4 to be cooled / condensed.
  • valve 21 of the return line 11 thus makes it possible to maintain the pressure and the mass of hydrogen in the storage 8 by direct reliquefaction.
  • the evaporation losses related to the filling of reservoirs 8 are then at least partly compensated by the sub-cooling of the hydrogen contained in the storage 4 (first or second solution) or by the subcooled hydrogen which comes directly from the liquefier 3 .
  • the system described can even allow a global saving on the cost of liquefaction.
  • the invention may make it possible, if necessary, to increase the subcooling of the liquid when the hydrogen demand is lower than the nominal capacity. Indeed, the capacity of production of sub-cooled hydrogen decreases with the level of subcooling. This can advantageously adjust the level of subcooling of the liquid contained in the storage 4.
  • the invention makes it possible to reduce gas losses by evaporation during transfers of cryogenic liquid in delivery trucks or other mobile tanks.
  • the solution can where appropriate take advantage of the hydrogen subcooled on existing liquefiers by adding a liquid cooling system and cooling the tanks 8 to fill.
  • the net liquefaction capacity of the existing unit can also be increased due to the reduction of the hydrogen vapors to be recovered.
  • the invention can be applied to gases other than hydrogen where appropriate.
  • hydrogen gas from the source can be at room temperature and have a pressure of 1.1 to 30 bar abs and a flow rate between 1 and 100 t / day.
  • the liquid hydrogen supplied by the liquefier 3 can have a pressure of between 1.05 and 12.8 bar and a temperature of between 20.4 and 33K.
  • the liquid hydrogen transferred to the tank 8 may have a pressure between 1.05 and 12 bar and a temperature between 20.4 and 33K.
  • the flash gas (vaporized) of the hot reservoir 8 to be filled can have a pressure of 1.3 and 5 bar abs and a temperature of 30 to 150K. This flash gas can be warmed to room temperature and then re-compressed to a pressure of 30 bar for example.
  • the hydrogen gas from the source 2 can be at room temperature and have a pressure of 1.1 to 30 bar abs and a flow of 1 to 100t / day but lower than the rate of the first configuration.
  • the liquid hydrogen supplied by the liquefier 3 may have a pressure of between 1.1 and 12 bar and a temperature of between the saturation temperature and 16 K.
  • the liquid hydrogen transferred to the tank 8 may have a pressure of between 1 , 1 and 12 bar (depending on whether the transfer is done by thermosiphon or via a pump) and a temperature of 20, 4K.
  • the flash gas (vaporized) of the hot reservoir 8 to be filled can have a pressure of 1.2 and 12 bar abs and a temperature of 30 to 150K.
  • the liquefied gas can be returned to the tank 8 at pressure conditions between 2.5 and 5 bar abs and a temperature of 30 to 50K.
  • the subcooled liquid can be transferred into the tank 8 in the gas phase of the latter.
  • one or more nozzles may be provided for this purpose. This or these nozzles are preferably oriented towards the top of the tank (theoretically the hottest zone). This makes it possible to improve the efficiency of the depressurization of the tanks 8.
  • the liquefier 3 is preferably configured to supply liquid (eg hydrogen) under pressure. It is thus possible to provide a natural hydraulic path that avoids installing a specific cryogenic machine to counteract the pressure drops on the circuit between the liquefier and the downstream end. This makes it possible to get rid of a compressor or a cryogenic pump which would complicate the installation (low power therefore significant thermal inputs, necessary maintenance, potential ice taking, ).
