The invention relates to a system for storing liquid hydrogen and for distributing gaseous hydrogen, comprising a source of liquid hydrogen (), at least two gaseous hydrogen tanks (-) to be filled and a transfer device comprising: a transfer unit () configured to transfer liquid hydrogen from the hydrogen source () to any of the tanks, a vapour compressor () having a first upstream end and a second downstream end fluidly connected to each of the tanks, a set of valves (-), a control device configured to issue a command to transfer the liquid hydrogen and to open and/or close one or more valves (-), the compressor () 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.

System for storing liquid hydrogen and for distributing pressurised gaseous hydrogen

A cryogenic tank for a space launcher, comprising a partition and delimiting top and bottom volumes communicating via at least one free central opening formed in the partition, so as, on the one hand, to allow for the flow of liquid by gravity from the top volume to the bottom volume via the central opening or openings and, on the other hand, to prevent the rising of the fluid from the bottom volume to the top volume via the central opening or openings under the action of acceleration forces, the tank also comprising at least one vent forming separate from the central opening or openings and providing fluid communication between the top and bottom volumes, the vent being configured to favor the migration of vapor from the bottom volume to the top volume and to prevent the rising of liquid from the bottom volume to the top volume.
