The invention relates to a method for filling an enclosure with a fluid until a target pressure is reached and then emptying the enclosure in due course, characterized in that the filling is performed from a first plurality of reservoirs at different pressures, successively starting with the reservoir at the lowest pressure and ending with the reservoir at the highest pressure, and in that the emptying is performed by transferring the contents of the enclosure into a second plurality of reservoirs, successively starting with the reservoir at the highest pressure and ending with the reservoir at the lowest pressure.

To enable a hydrogen tank to be efficiently filled with hydrogen even when the hydrogen tank has a large capacity, hydrogen filling at the nozzle flow is prohibited when the nozzle flow of a nozzle is larger than the receptacle flow of a receptacle or when the receptacle flow is unknown under the condition that the nozzle and the receptacle can be connected to each other.

A cryogenic flux capacitor (CFC) storage system includes a CFC core module having an inner container comprising one of: (i) a vessel; and (ii) a membrane that contains a substrate material. Fluid paths in the substrate material distribute fluid during charging and discharging. Nanoporous media is attached to the substrate material that receives fluid via physical adsorption during charging. A thermally conductive support layer maintains position of the substrate material within the inner container. The thermally conductive support layer conductively distributes thermal energy within the inner container. An outer insulating container encompasses the CFC core module. At least one fluid conduit directs transfers of the fluid in a gaseous or liquid state from a source subsystem into the CFC core module during charging and the fluid in a gaseous state out of the CFC core module during discharging to a destination subsystem that utilizes the fluid in a gaseous state.

A method includes supplying a mobile pressure tank. The mobile pressure tank includes a pressure tank, with a trailer. The mobile pressure tank also includes an integrated spill containment system, the integrated spill containment system affixed to either the trailer or the pressure vessel and a maximum pressure safety valve positioned on the top portion, the maximum pressure safety valve having a maximum pressure. Further the mobile pressure tank includes a nitrogen blanket system, the nitrogen blanket system having a nitrogen pressure set point. The method also includes determining a fluid to be pumped into the pressure vessel, the fluid having a fluid vapor pressure and setting the nitrogen pressure set point above the fluid vapor pressure. The method further includes pumping the fluid into the pressure tank and relieving pressure in the pressure tank by allowing nitrogen to vent through the back pressure valve.

A process for capturing and storing natural gas from a natural gas production facility includes flowing a natural gas stream through a first natural gas flow path extending from a wellhead to a sales gas pipeline. In response to receiving an indication of a process upset in the sales gas pipeline, at least some of the natural gas stream is diverted from the first natural gas flow path to a second natural gas flow path leading to a storage system having a storage vessel with one or more adsorbent beds such that the natural gas stream diverted to the second natural gas flow path is adsorbed by the one or more adsorbent beds and stored in the storage system.
