Embodiments of the present disclosure may include a partition for a fuel tank. The partition may include a sheet of material extending laterally within an interior mid-region of the fuel tank. The sheet may have a length and a width that are at least substantially equal to a length and a width of the mid-region of the fuel tank, and the sheet may be shaped to conform to an interior perimeter of the mid-region of the fuel tank. The partition may also be configured to substantially divide the fuel tank into an upper interior region located above the partition and a lower interior region located below the partition.

A device and a method for keeping a liquefied gas store cold having a cryogenic refrigerator, a subcooling circuit having an aspiration end intended to be seated in a liquefied gas store, a heat exchanger exchanging heat between the aspirated subcooling circuit and the refrigerator, the subcooling circuit having at least one injection end configured to inject the fluid cooled in the heat exchanger into the store, the device further including a boil-off gas recovery pipe having an upstream end intended to be connected to the store to recover the boil-off gas, the recovery pipe comprising a downstream end intended to be connected to a consumer, the device having a bypass pipe and a set of valves configured to enable boil-off gas to be transferred from the recovery pipe to the subcooling circuit.

A system and method for hydrogen storage, and delivery. The system includes a hydrogen storage tank, a first pump disposed within the hydrogen storage tank, and a second pump disposed outside of the hydrogen storage tank. The hydrogen storage tank is to store gaseous hydrogen and liquid hydrogen. The first pump is to pump out liquid hydrogen out of the storage tank, producing a low pressure flow. The second pump is to receive this low pressure flow and produces a high pressure flow of liquid hydrogen. The system can also include a thermal device disposed within the hydrogen storage tank to heat gaseous hydrogen when a pressure within the hydrogen storage tank drops below a predetermined minimum pressure. The system can also include a heat exchanger to receive the high pressure flow of liquid hydrogen from the second pump.

Disclosed is a device and method for quickly replacing a tested flow meter in a liquid hydrogen flow measurement standard facility. The present disclosure includes a tested cold box, wherein the tested flow meter is located in the evacuated tested cold box, the tested cold box is connected to the liquid hydrogen flow measurement standard facility through a bayonet structure; a first vacuum pump, configured to evacuate the tested cold box after replacing the tested flow meter; a second vacuum pump, configured to evacuate a tested pipeline; a precooling device, configured to precool the tested pipeline and the tested flow meter connected to the tested pipeline after the tested pipeline is evacuated.
