A method and system of storing and transporting gases comprising mixing the gases with liquid natural gas to form a mixture. The mixture is a liquid-liquid mixture or slurry, and is stored in vessel configured for maintaining the mixture at a first location. The mixture is transported to a second location for storage in vessel for maintaining the mixture. The mixture is removed from the second location storage vessel for separation and use in additional processes.

A method and apparatus for compressing gases and supplying fuel to a gaseous fuel consuming device, such as a gaseous fueled vehicle or the like. One embodiment includes a gas compressor for compressing the gaseous fuel to an array of tanks having predetermined initial set points which are increasing for tanks in the array. One embodiment provides a selecting valve having first and second families of ports wherein the valve can be operated to select a plurality of ports from the first family to be fluidly connected with a plurality of ports with the second family, and such fluid connections can be changed by operation of the valve.

Disclosed is a BOG reliquefaction system. The BOG reliquefaction system includes: a compressor compressing BOG; a heat exchanger cooling the BOG compressed by the compressor through heat exchange using BOG not compressed by the compressor as a refrigerant; a pressure reducer disposed downstream of the heat exchanger and reducing a pressure of fluid cooled by the heat exchanger; and a second oil filter disposed downstream of the pressure reducer, wherein the compressor includes at least one oil-lubrication type cylinder and the second oil filter is a cryogenic oil filter.

A filter device for a gas container removes foreign substances mixed with gas in the gas container, and is integrally mounted with the gas container so as to ensure a maximum capacity of the gas container while providing a larger gas filter compared to existing external gas filters.

A cryogenic fluid purification device comprising: a first container defining an interior region; a second container defining an interior region in fluid communication with the interior region of the first container; and a cryogenic fluid in contact with an exterior of the second container.

The system can include: a heat exchanger, a set of valves, a sensor suite, and a controller The system can optionally include or be used with a catalyst, a set of barriers, and/or an enclosure. However, the system can additionally or alternatively include any other suitable set of components. The system functions to facilitate cooling of a pressurized fluid (e.g., high pressure hydrogen gas). Additionally or alternatively, the system can function to catalyze fluid state change (e.g., hydrogen spin conversion, etc.) within the pressurized fluid. For example, the system can be used to convert hydrogen from a high-pressure gaseous hydrogen (GH.sub.2) state or high-pressure supercritical hydrogen (ScH.sub.2) state to the cryo-compressed hydrogen (CcH.sub.2) state without hydrogen liquefaction (fluid state transition to liquid hydrogen, LH.sub.2).

Embodiments of systems, methods, and canisters to filter flammable vapor and release filtered vapor during an overpressure event are disclosed. An embodiment of a method may include flowing a fluid from a sample vessel to a pressure relief device. The fluid may include one or more liquids and one or more flammable gases. The method may include flowing the fluid from the pressure relief device to a pressure flow reducer cylinder when the overpressure event occurs, reducing the pressure flow of the fluid in the pressure flow reducer cylinder, and flowing the reduced pressure flow fluid from the pressure flow reducer cylinder to a canister. The method also may include adsorbing vapors of the one or more flammable gases of the fluid when present in the reduced pressure flow fluid in the canister, thereby to obtain filtered vapor, and releasing the filtered vapor from the canister.
