A liquefied natural gas (LNG) management system that stores natural gas in a liquefied state in an isothermal storage tank. A modular multi-fueling platform is in fluid communication with the isothermal storage tank. The modular multi-fueling platform includes a LNG conditioning tank, a compressor, a heat exchanger, a heater, plumbing, associated valves, various sensing transmitters, and a programmable logic computer (PLC). Data acquired by the PLC determines actions by the modular multi-fueling platform, including operation of valves, the compressor, etc. The system transfers LNG between the storage tank, the conditioning tank, and a cargo tank (consumer's vehicle tank). The system employs steps of heating and compressing the LNG and boil off gas to maintain the LNG at temperature. The system employs pressure differences for transferring the LNG between tanks.

Device for filling with liquefied gas comprising a fluid circuit provided with a first pipe for liquid transfer comprising a first end that is intended to be connected to a source of liquefied gas and a second end that is intended to be connected to a tank to be filled, a second pipe for gas transfer comprising a first end that is intended to be connected to the source of liquefied gas and a second end that is intended to be connected to said tank to be filled, the circuit comprising at least one third transfer pipe connecting the first and second transfer pipes, and a vent device connected to the first and second transfer pipes via a set of one or more safety valves, the circuit comprising a set of one or more valves for controlling the streams of fluid in the pipes of the circuit, the device comprising a system for gas flushing of the circuit, characterized in that the flushing system comprises a first source of pressurized gas, and a first set of one or more flushing pipes connecting the first source of pressurized gas in parallel both to the first and second transfer pipes via a set of one or more valves.

A device for filling a tank or tanks with pressurized gas comprising a circuit comprising a plurality of upstream ends connected respectively to separate pressurized gas sources, at least one compressor, at least one buffer storage, a set of controlled valves and at least one downstream end intended to be connected to the tank(s) to be filled, the device further comprising an electronic control member configured to control the valves and/or the compressor in order to ensure a transfer of gas into the tank from at least one source and/or at least one buffer storage and/or via the compressor, the device comprising a set of sensors for measuring the pressure in the sources and the buffer storages, the control member comprising member for receiving or generating signal representative of the filling demand from a relatively high demand to a relatively low demand, the control member being configured to ensure the transfer of gas into the tank according to at least a first transfer mode using the source having the highest pressure and a second transfer mode using a source having a pressure lower than this highest pressure in response, respectively, to a relatively high or low filling demand.

Method for delivering liquefied gas, especially hydrogen, by means of at least one mobile storage facility, especially a storage facility transported by lorry, comprising a step of filling the mobile storage facility with liquefied gas at a source plant, the mobile storage facility containing, after filling, liquefied gas and a fraction of the vaporized gas, the method comprising a movement of the mobile storage facility from the source plant to a receiving station and a transfer of liquefied gas from the mobile storage facility to the receiving station, characterized in that it comprises a step of interim cooling of the liquefied gas contained in the mobile storage facility between the source plant and the receiving station by means of a cooling device comprising a liquefied gas tank and a refrigerating element.

The invention relates to a device for supplying a gaseous fuel to an engine that comprises a gas accumulator for receiving highly pressurized gaseous fuel, a gas buffer for receiving medium pressurized gaseous fuel, a gas supply device for delivering a gaseous fuel into an engine combustion space, a first gas line that connects the gas accumulator to the gas buffer and whose gas flow can be regulated via a first valve, a second gas line that connects the gas accumulator to the gas buffer and whose gas flow can be regulated via a second valve, and a third gas line that connects the gas buffer to the gas supply device.
