[Problem] When configuring a device for storing and supplying fluid, each components such as vessels, valves/pipes and the like, are placed independently outside a vessel that stores the fluid, and even if these components are small, the volume of the area between the components cannot be effectively used because each of them occupies the surrounding area, and when the total size of the device is limited, it is difficult to ensure a sufficient volume of the vessel that stores the fluid. The present invention provides a design for a configuration of a mechanism consisting of components such as valves/pipes and the like, that functions for storing and exhausting the fluid inside the storage vessel to innovatively improve the volume usage efficiency of the device.

Aircraft fuel system including a fuel vessel containing a non-mixture fuel. A protective vessel is arranged about the fuel vessel such that the fuel vessel is contained within the protective vessel and a protective space is defined between an outer surface of a vessel wall of the fuel vessel and an inner surface of a vessel wall of the protective vessel. At least one mounting structure fixedly positions the fuel vessel within the protective vessel. A fuel consumption device configured to consume the non-mixture fuel. A fuel output fluidly connects an interior of the fuel vessel to the fuel consumption device, the fuel output being fluidly isolated from the protective space. A relief output fluidly connects the protective space to a relief flow path, the relief output and relief flow path configured to vent gas from the protective space and remove any non-mixture fuel from the protective space.

A system and method for unloading highly pressurized compressed natural gas from transport vessels by depressurizing the gas through flow lines linking a series of automated flow control valves that lower the gas pressure to a predetermined level, the valves being linked in series with and separated by heat exchangers in which the lower pressure gas flowing through the system is also reheated to a predetermined temperature by a heat exchange medium recirculation system in which the heat exchange medium is reheated by a heat source that can be internal to the system. The use of a minor portion of the depressurized and reheated gas as fuel gas to reheat the heat exchange medium is also disclosed. The subject system can be skid-mounted if desired.

A method of operating a hydrostatically compensated compressed air energy storage system in a first charging mode including conveying the compressed air at a nearly constant first operating pressure which displaces a corresponding volume of compensation liquid from the layer of compensation liquid out of the accumulator, and a second charging mode including conveying additional compressed air into the accumulator while compensation liquid is not displaced from within the accumulator so that the pressure of the layer of compressed air increases to a second operating pressure that is greater than the first operating pressure.

Systems and methods are provided for a combined defuel and priority panel for a fueling station. The defuel and priority panel is configured to defuel a compressed natural gas (CNG) vehicle and direct the defueled gas to fuel other CNG vehicles at the panel fueling and defueling site. The defuel and priority panel is also configured to store defueled gas in defuel storage tanks, which can then be used to later fuel CNG vehicles.

Configuring a high-vapor-pressure (HVP) material comprising a plurality of component hydrocarbons; flashing the HVP material from an HVP liquid to an HVP vapor as the HVP liquid is introduced into an evacuated portion of a containment vessel; introducing a relief mass from a process relief event occurring outside the containment vessel to mix with the HVP material in the containment vessel; and distributing energy from the process relief mass within the containment vessel using a plurality of energy absorption processes in the component hydrocarbons as the plurality of component hydrocarbons respectively condense to liquid phases over time. The evacuated portion of the containment vessel may be a headspace vacuum above a low-vapor-pressure (LVP) liquid within the containment vessel. The HVP material may comprise C4-C10 hydrocarbons. The HVP material may comprise a plurality of component hydrocarbons having diverse boiling points and vapor pressures, that absorb and distribute the relief mass energy.

The invention relates to a method for storing and distributing liquefied hydrogen using a facility that comprises a store of liquid hydrogen at a predetermined storage pressure, a source of hydrogen gas, a liquefier comprising an inlet connected to the source and an outlet connected to the liquid hydrogen store, the store comprising a pipe for drawing liquid, comprising one end connected to the liquid hydrogen store and one end intended for being connected to at least one mobile tank, the method comprising a step of liquefying hydrogen gas supplied by the source and a step of transferring the liquefied hydrogen into the store, characterized in that the hydrogen liquefied by the liquefier and transferred into the store has a temperature lower than the bubble temperature of hydrogen at the storage pressure.

A system and a method for dispensing a liquefied fuel (e.g., hydrogen) are provided. The system includes a cryotank for storing a liquefied fuel, a first liquid pump and a second liquid pump. The first pump has a first maximum flow rate and pumps a first stream of the liquefied fuel having a first pressure. The second pump has a second and lower maximum flow rate, and pumps a second stream of the liquefied fuel has a second and higher pressure. Each pump is connected with a heat exchanger to vaporize a stream of the liquefied fuel to provide a respective vaporized substream. Each pump is also connected with a mixer, which combines the respective vaporized substream and a respective second substream of the liquefied fuel to provide a respective gaseous fuel stream. The gaseous fuel streams can be separately or jointly dispensed to one or more vehicles through a piping manifold and at least one dispenser.
