A pipe extends through the at least one opening, the pipe having a sleeve assembly positioned around the pipe. The sleeve assembly also extends through the opening. The sleeve assembly includes a sleeve, at least one layer of insulation, and an inner flange. The inner flange is located on a first end of the sleeve and is coupled to the pipe. The sleeve, in turn is coupled to the tank such that the inner flange is located within the storage tank. The at least one layer of insulation is positioned in an annulus between the pipe and the sleeve.

A cryogenic vessel includes an outer vessel at least partially formed from a reinforced concrete. The cryogenic vessel further includes an inner vessel disposed in the outer vessel. The cryogenic vessel further includes an airtight liner disposed between the inner vessel and the outer vessel, wherein the liner is anchored to the outer vessel. The cryogenic vessel further includes a vacuum space disposed between the inner vessel and the liner, wherein an insulation material is disposed in the vacuum space.

Embodiments provide systems and methods for taking power from an electric power grid and converting it into higher-pressure natural gas for temporary storage. After temporary storage, the higher-pressure natural gas may be expanded through an expansion engine to drive a generator that converts energy from the expanding natural gas into electrical power, which may then be returned to the electric power grid. In this way, the disclosed systems and methods may provide ways to temporarily store, and then return stored power from the electric power grid. Preferably, the components of the system are co-located at the same natural gas storage facility. This allows natural gas storage, electrical energy storage, and electrical energy generation to take place at the same facility.

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.
