Abstract: A thermal storage subsystem may include at least a first storage reservoir configured to contain a thermal storage liquid at a storage pressure that is greater than atmospheric pressure. A liquid passage may have an inlet connectable to a thermal storage liquid source and configured to convey the thermal storage liquid to the liquid reservoir. A first heat exchanger may be provided in the liquid inlet passage and may be in fluid communication between the first compression stage and the accumulator, whereby thermal energy can be transferred from a compressed gas stream exiting a gas compressor/expander subsystem to the thermal storage liquid.

Abstract: A compressed gas energy storage system may include an accumulator for containing a layer of compressed gas atop a layer of liquid. A gas conduit may have an upper end in communication with a gas compressor/expander subsystem and a lower end in communication with accumulator interior for conveying compressed gas into the compressed gas layer of the accumulator when in use. A shaft may have an interior for containing a quantity of a liquid and may be fluidly connectable to a liquid source/sink via a liquid supply conduit. A partition may cover may separate the accumulator interior from the shaft interior. An internal accumulator force may act on the inner surface of the partition and the liquid within the shaft may exert an external counter force on the outer surface of the partition, whereby a net force acting on the partition is less than the accumulator force.

Abstract: A hydrostatically compensated compressed air energy storage system may include an accumulator disposed underground and a compressor/expander subsystem in fluid communication. A compensation shaft may extend between an upper and a lower end and define a shaft depth. An upper end wall can cover the upper end of the shaft. A compensation liquid reservoir can be offset above the upper end wall by a reservoir elevation that is at least about 15% of the shaft depth. A compensation liquid flow path may extend between the compensation liquid reservoir and the accumulator and can include the compensation shaft and a liquid supply conduit extending between the compensation liquid reservoir and the upper end of the compensation shaft whereby a total hydrostatic pressure at the lower end of the shaft is greater than a hydrostatic pressure at a depth that is equal to the shaft depth.

Abstract: A hydrostatically compensated, compressed gas energy storage system can include an accumulator containing a layer of compressed gas at between about 20 bar and about 90 bar above a layer of compensation liquid that has a density of at least 1500 kg/m3. A compressor and expander subsystem may be configured to selectably convey compressed gas into the accumulator and to extract gas from the accumulator. The system may be operable in at least a charging mode in which the compressor and expander subsystem conveys gas into the layer of compressed gas thereby displacing a corresponding volume of compensation liquid from the layer of compensation liquid within the accumulator out of the accumulator via the compensation liquid flow path thereby maintaining the layer of compressed gas at substantially the accumulator pressure during the charging mode.

Abstract: A method of transitioning a hydrostatically compensated compressed air energy storage system from an operating mode to a dewatered maintenance state may include a) charging an accumulator to a fully charged state where the air water interface is at a charge plane by conveying compressed air at a storage pressure into the layer of compressed air using a gas compressor/expander subsystem thereby displacing a corresponding amount of compensation liquid from the layer of compensation liquid out of the accumulator into the compensation liquid flow path and from the compensation liquid flow path into the compensation liquid reservoir until the accumulator is substantially free of the compensation liquid, b) fluidly sealing the compensation liquid flow path thereby isolating a residual amount of the compensation liquid, and c) depressurizing the accumulator interior to a service pressure that is lower than the storage pressure.
