A motor vehicle with a pressure vessel system includes at least a first pressure vessel arranged in a first region of the motor vehicle and at least one second pressure vessel arranged in a second region of the motor vehicle having a lower intrusion probability than the first region. Fuel is preferentially removed first primarily from the at least one first pressure vessel. When the lower limit of fuel level or fuel temperature is reached in the at least one first pressure vessel, fuel is removed from the at least one second pressure vessel. If the fuel supply rate from the at least one first pressure vessel is lower than an overall fuel supply rate for an energy converter, fuel is removed from the at least one second pressure vessel to meet the overall fuel supply rate needed by the energy converter.

A method for inhibiting the formation of carbonyl compounds in a gas cylinder containing carbon monoxide wherein the gas cylinder is in fluid communication with a valve assembly wherein the valve assembly connects to a threaded opening in the gas cylinder by a threaded assembly by coating interior and exterior components of the valve assembly selected from the group consisting of an inlet port, an outlet port, a diaphragm and a lower spindle with an amorphous hydrogenated silicon compound. A valve assembly containing the coated interior and exterior components is also disclosed.

A method for filling tanks with pressurized gas via a filling station comprising at least one source of pressurized gas and a fluid circuit for transferring the gas, comprising a first end linked to the at least one gas source and a second end provided with a transfer line intended to be removably connected to the tanks to be filled, the circuit comprising a first isolation valve, a flow or pressure regulation member, a heat exchanger for cooling the gas transferred to the tank to be filled and a second isolation valve, the method comprising successively filling a first tank then a second separate tank, characterized in that, on completion of the filling of the first tank, the first and second isolation valves are closed to trap a reserve supply of pressurized gas in the circuit between said two valves and in that the reserve supply of gas is used to fill the second tank.

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.

The present invention is to provide a hydrogen refueling system capable to cool down the H2 pre-cooling heat exchanger fast enough when a FCV enters the HRS, so that there is no or very minimal waiting time for the customer before starting refueling. A hydrogen refueling system including a cryogenic fluid tank that stores a cryogenic fluid, a dispenser that supplies H2 to a vehicle, including a heat exchanger that cools H2 with the cold and/or cryogenic fluid provided from the cryogenic fluid tank, an inlet line that sends the cold and/or cryogenic fluid to the heat exchanger from the cryogenic fluid tank, an outlet line that collects the cryogenic fluid fed from the heat exchanger, and an injection valve that is provided in the inlet line.

A methane transportation system is provided. The system may include a methane source configured to dispense methane at a first location, and an underwater vehicle. The underwater vehicle may include a propulsion system configured to transport the underwater vehicle underwater from the first location to a second location and a vessel defining a storage chamber configured to receive water and the methane from the methane source. The storage chamber of the vessel may have a pressure exceeding one atmosphere and a temperature during transport from the first location to the second location sufficient to form methane clathrate in the storage chamber. The system may further include a methane receiver configured to receive the methane released from the storage chamber at the second location. Related methods are also provided.

When a pressure accumulator tank A3a is used as a low-pressure hank, a controller sends an open control signal to an electromagnetic open/close valve A10a to open the electromagnetic open/close valve A10a so that hydrogen in the pressure accumulator tank A3a can be supplied to a tank to be filled (not shown) of an FCV. In parallel with this, the controller sends an open control signal to a first electromagnetic open/close valve 6a and a second electromagnetic open/close valve 6b to open the first and second electromagnetic open/close valves 6a and 6b so that hydrogen can be supplied also from a compressor 2 to the tank to be filled of the FCV.
