A device for transferring a fluid from a supply tank to a receiver tank includes at least one duct for charging the receiver tank with liquid and at least one duct for return of the gas. The gas return duct is configured to transfer the gas contained in the receiver tank at a pressure close to or significantly different from the pressure of the supply tank.

In a device and a method for guiding a hydrogen fueled vehicle based on a hydrogen pressure of a fuel tank of the hydrogen charging station, information on a hydrogen charging station including the hydrogen pressure of the fuel tank of the hydrogen charging station is received from a server, and a charging station determined to be suitable for charging the hydrogen fueled vehicle is selected in consideration of an importance of each item obtained from a user of the hydrogen fueled vehicle based on items including at least one of a price of hydrogen charging, a charging standby time, a charging taking time, whether the hydrogen fueled vehicle is able to be fully charged, and a distance to the hydrogen charging station determined based on the information on the hydrogen charging station.

Apparatus, methods and technologies are described for utilizing a liquid organic hydrogen carrier (LOHC) fueling station to supply fresh or hydrogen laden LOHC and to recover spent or hydrogen depleted LOHC liquid fuels from mobile vehicles and tanker trucks to support the use of LOHC as carbon-neutral hydrogen fuels to power vehicles, to generate and store electricity, to generate and capture hydrogen, and to replace the use of conventional hydrocarbon fuels while maintaining an overall carbon-neutral balance with respect to the environment. The disclosure includes apparatus, methods and technologies to resupply a modular LOHC fueling station, to store, dispense and recover LOHC fuels, and to transfer the LOHC liquid fuels while balancing displaced vapors to maintain an overall carbon-neutral environmental footprint.

A type IV conformable pressure vessel is provided comprising an elongated folded tank and a valve assembly configured to pass fluid into and out of an interior of the tank through first and second filling couplers directly connected to a respective first and second end of the tank. The tank has at least two chambers for the storage of fluid. The valve assembly receives fluid from an external source, selectively provides the external fluid through a Venturi nozzle into a mixing chamber, recirculates fluid from the second end of the tank into the mixing chamber, and delivers the mixture of the recirculated fluid and the external fluid to the first end of the tank.

The present invention relates to a gas treatment system and a ship including the same. The gas treatment system treats liquefied gas as heavier hydrocarbons or ammonia. The gas treatment system includes: a fuel tank storing liquefied gas as a fuel to be supplied to a propulsion engine of a ship; a liquefied gas supply line supplying the liquefied gas of the fuel tank in a liquid phase to the propulsion engine, the liquefied gas supply line having a high pressure pump provided thereon; a reliquefaction apparatus liquefying boil-off gas generated in a cargo tank storing liquefied gas; and a liquefied gas collection line collecting the liquid liquefied gas discharged from the propulsion engine upstream of the high pressure pump. The reliquefaction apparatus transfers the liquefied boil-off gas to the fuel tank, thereby allowing the liquefied boil-off gas to be supplied to the propulsion engine by the high pressure pump.

A filling apparatus that does not significantly reduce a required pressure immediately after a start of hydrogen filling, and can reliably fill fuel cell vehicles and the like. The filling apparatus (100) includes a control unit (10), and the control unit (10) has a function of boosting pressure required from a hydrogen filling apparatus (100) to a rear facility (200) until initial pressure measurement is completed. The control unit (10) may have a function of determining whether or not communication filling is established, and when communication filling is established, setting a pressure higher than an internal pressure of a tank received from a vehicle side by a predetermined pressure (for example, 5 MPa) as a pressure required for the rear facility (200) at an initial stage of filling.

Disclosed is a liquefied hydrogen filling apparatus configured such that connection between liquefied hydrogen injection lines is performed stepwise, whereby there is no concern of leakage of liquefied hydrogen the moment the liquefied hydrogen injection lines are connected to each other, and therefore it is possible to guarantee safety and to prevent loss of fuel. In addition, the state of connection between the liquefied hydrogen injection lines is securely maintained, whereby there is no concern of separation due to internal pressure at the time of filling or other external force, and therefore it is possible to perform safe filling.

A cryogenic fluid transfer device comprising a first tank, a second tank, and a fluid transfer circuit, wherein the first tank comprises a cryogenic fluid distribution tank configured to store a cryogenic fluid in a liquid phase in a lower part thereof and in a gaseous phase in an upper part thereof, wherein the second tank comprises a cryogenic receiving tank configured to house the cryogenic fluid in liquid phase in a lower part thereof and in gaseous phase in an upper part thereof, wherein the fluid transfer circuit is configured to connect the first and second tanks, the fluid transfer circuit comprising a first pipe connecting the upper parts of the first and second tanks and comprising at least one valve, and a second pipe connecting the lower part of the first tank to the second tank that comprises a pump that has an inlet connected to the first tank and an outlet connected to the second tank, wherein: the pump and the at least one valve of the first line are configured so as to ensure a fluidic connection of the upper parts of the first and second tanks by opening the at least one valve during a transfer of the cryogenic fluid in liquid phase from the first tank to the second tank with the pump.
