    摘要： Methods and associated systems for storing compressed air and extracting energy from the compressed air are disclosed. An exemplary method comprises: compressing air; storing the compressed air in a first storage tank at a first pressure; transferring the compressed air from the first storage tank to a second storage tank; storing the compressed air in the second storage tank at a second pressure lower than the first pressure; discharging the compressed air from the second storage tank; and extracting energy from the compressed air discharged from the second storage tank. The method may also comprise adding heat to the compressed air between the first storage tank and the second storage tank.

    摘要： A method for operating a compressed air energy storage system is provided. The method can include compressing a process gas with a compressor train to produce a compressed process gas and storing the compressed process gas in a compressed gas storage unit. The method can also include extracting the compressed process gas from the compressed gas storage unit to an expansion assembly through a feed line. A valve assembly fluidly coupled to the feed line can be actuated to control a mass flow of the compressed process gas from the compressed gas storage unit to the expansion assembly. The method can further include heating the compressed process gas in a preheater fluidly coupled to the feed line upstream from the expansion assembly, and generating a power output with the expansion assembly.

    摘要： This is a system that stores energy by compressing atmospheric air and confining it in tanks or caverns, combining the thermodynamic cycle followed by the atmospheric air (Brayton cycle) with another thermodynamic cycle followed by an auxiliary fluid, that is confined in the same cavern within a membrane, following two sections of a Rankine cycle, one during the air compression and entry into the cavern process and the other during the air outlet and turbining process, using heat from the exhaust gases from the turbine as a heat source for an additional Rankine cycle, and being able to use the tanks or caverns for making an extra constant volume heating of compressed air and/or of the auxiliary fluid.

    摘要： A compressor/motor has fluid processing stages, each having ports through which a fluid is accepted in one volume and expelled in another volume. A system of valves selectively couples the ports to define, for a first process of a cycle, a unidirectional fluid path through the fluid processing stages that expels the fluid from path-adjacent fluid processing stages in incrementally smaller volumes. In a second process of the cycle, a reverse unidirectional fluid path is defined by the valves where the fluid expelled from path-adjacent fluid processing stages is in incrementally larger volumes. A mechanical interface coupled to the fluid processing stages conveys a force to the fluid processing stages to compel the fluid through the fluid path in the first process or conveys the force from the fluid processing stages that is compelled by the fluid traversing the reverse fluid path.
