  • Publication number: 20220136654
    Abstract: Device and method for filling pressurized-gas tanks, comprising a fluid transfer circuit provided with an upstream end intended to be connected to a source of gas and at least two parallel downstream ends intended to be connected to distinct tanks that are to be filled, the transfer circuit comprising a temperature regulating member for regulating the temperature of the gas transferred from the source towards the downstream ends, the gas temperature regulating member being positioned in the transfer circuit upstream of the at least two downstream ends, which means to say that the gas temperature regulating member is common to the at least two downstream ends, characterized in that the at least two downstream ends of the circuit each comprise a respective control member for controlling the flow rate and/or the pressure of the transferred gas and configured to control the flow rate and/or the pressure in each of the downstream ends independently.

  • Publication number: 20220074397
    Abstract: Device for pumping liquid hydrogen including, arranged in series between an inlet for fluid to be compressed and an outlet for compressed fluid, a first compression member with a piston forming a first compression stage and a second compression member with a piston forming a second compression stage. The first compression member compresses the liquid hydrogen to a supercritical state. The second compression member compresses the supercritical hydrogen from the first compression member to an increased pressure, in particular, between 200 and 1000 bar.

  • Publication number: 20220017358
    Abstract: Device and method for filling pressurized gas tanks, particularly vehicle pressurized hydrogen tanks, the device comprising a liquefied gas source, a transfer circuit comprising two parallel transfer lines each having an upstream end linked to the liquefied gas source, at least two separate downstream ends intended to be each removably connected to a tank to be filled, each of the two transfer lines comprising: a pump, a vaporizer for evaporating the pumped fluid, a branch for bypassing the vaporizer and a distribution valve(s) set configured to control the flow of fluid pumped and distributed between the vaporizer and the branch line, the device further comprising a storage buffer(s), which storage buffer(s) is(are) connected in parallel to each of the two transfer lines via a set of valves.

  • Patent number: 11060665
    Abstract: Installation and method for filling tanks with pressurized gas in which fluid supplied to the buffer storage reservoir is at a relatively higher first temperature while fluid is being withdrawn from the buffer storage reservoir to fill a tank and fluid is supplied to the buffer storage reservoir at a relatively lower second temperature when fluid is not being withdrawn from the buffer storage reservoir to fill a tank.

  • Publication number: 20200248870
    Abstract: Method for filling a storage vessel with liquefied gas by means of a tank of liquefied gas, the method comprising a step of transferring liquefied gas from the tank into the storage vessel by means of a pressure differential, wherein the storage vessel prior to the transfer step has an internal pressure higher than the internal pressure of the tank, the method comprising, prior to the transfer step, a step of placing the tank and the storage vessel in fluidic communication in order to ensure a drop in the pressure in the storage vessel to the benefit of the tank and a step of increasing the pressure in the tank using a pressurizing device.
