An apparatus for fastening a pair of gas vessels includes: a plurality of first units formed of a composite material, spaced apart from each other in parallel with each other in a length direction of the gas vessel, and having the pair of gas vessels seated on both sides thereof; a second unit formed of a composite material and extending in the length direction of the gas vessels to integrally connect the plurality of first units; and a plurality of fastening units each of which extending along a circumference of the gas vessels to enclose the gas vessels seated on the first units and having both ends connected to the first units.

Embodiments of systems and methods for transporting fuel and carbon dioxide (CO.sub.2) in a dual-fluid vessel thereby minimizing transportation between locations are disclosed. In an embodiment, the dual-fluid vessel has an outer shell with two or more inner compartments, positioned within the outer shell, including a first inner compartment for storing CO.sub.2 and a second inner compartment for storing fuel. The dual-fluid vessel may connect or attach to a transportation vehicle to thereby allow transportation of the fuel and CO.sub.2. Insulation may provide temperature regulation for the fuel and CO.sub.2 when positioned in the respective first and second inner compartments. One or more ports having an opening in and through the outer shell and a fluid pathway to one or more of the first inner compartment or the second inner compartment may provide fluid communication through the opening and fluid pathway for loading/offloading the fuel and/or CO.sub.2.

An aircraft comprises a hydrogen-fuelled propulsion system, a plurality of like generally cylindrical hydrogen storage tanks and a conveying system arranged to convey hydrogen from the hydrogen storage tanks to the hydrogen-fuelled propulsion system. The aircraft further comprises a fuselage having a cargo bay (502) including one or more (510A-G) of the plurality of hydrogen storage tanks, the longitudinal axes (511A-G) of the one or more hydrogen storage tanks within the cargo bay extending parallel to the longitudinal axis (501) of the fuselage and lying in one or more planes (595, 597) extending across the width dimension of the cargo bay. The hydrogen storage tanks within the cargo bay have a common aspect ratio R in the range 4.2 ≤ R ≤ 25.7, allowing the volume of space with the cargo bay occupied by stored hydrogen to be maximised or approximately maximised.

A control unit for a pressure container system comprising at least one pressure container with a pressure container valve designed to conduct fuel from the pressure container into a removal line for supplying an energy converter. The control unit is designed to determine that a fueling procedure of the pressure container is occurring or has occurred. In response thereto, the control unit is additionally designed to cause the pressure container valve to open in a pulsed manner temporally prior to a removal request for fuel for operating the energy converter so that the pressure in the removal line approximates the pressure in the pressure container.

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 pressure vessel includes: a barrel part disposed in a predefined square area and having a diameter corresponding to a length of one side of the square area; a first nozzle member disposed at one end of the barrel part; a second nozzle member disposed at an opposite end of the barrel part; and clamp rings disposed in the square area, positioned outside the barrel part, and configured to lock the first and second nozzle members to the barrel part, thereby improving spatial utilization and a degree of design freedom.

A filling station comprises a filling device for an automated filling of a gas bottle inserted in the filling station and a filling device for refueling a motor vehicle, wherein the filling device for an automated filling of a gas bottle inserted in the filling station is arranged adjacent to the filling device for refueling a motor vehicle.

Device for filling tanks with pressurized gas, in particular hydrogen gas tanks of motor vehicles, the device comprising at least one gas source, a transfer circuit comprising at least one upstream end connected to the source and at least one downstream end intended to be connected in removable fashion to a tank to be filled, the transfer circuit additionally comprising, between its upstream and downstream ends, a set of buffer storage container(s) which is (are) connected in parallel to the transfer circuit via a set of respective connecting valve(s), the transfer circuit comprising a portion of pipe(s) forming a loop, a plurality of the buffer storage container(s) being connected in parallel to the said loop, characterized in that the transfer circuit comprises a plurality of separate downstream ends each intended to be connected in removable fashion to a respective tank to be filled, the said downstream ends being connected in parallel to the said loop and comprising a set of respective linking valves, so that control of the connecting valves and of the linking valves makes it possible to bring at least one first buffer storage container into fluidic communication, via the loop, with a first downstream end and, simultaneously, to bring at least one second buffer storage container into fluidic communication, via the loop, with a second downstream end and/or to bring two separate buffer storage containers into fluidic communication.

The present disclosure generally relates to a multiple receptacle fuel filling and storage system in a vehicle and/or powertrain, and a method of using the same.

A method for transferring cryogenic fluid from a storage tank (2; 12; 16) to a receiver (6; 8; 10; 14; 16; 18) like a receiving tank or to an application device, according to the invention comprises the steps of: a—pumping cryogenic liquid from the storage tank (2; 12; 16), b—vaporising at least partially the pumped cryogenic liquid, c—pressurising the storage tank (2; 12; 16) with the vaporised cryogenic liquid, and d—transferring cryogenic fluid to the receiver (6; 8; 10; 14; 16; 18) with cryogenic fluid from the storage tank (2; 12; 16) through a feed line (4) between the storage tank (2; 12; 16) and the receiver (6; 8; 10; 14; 16; 18).
