Abstract: A method of operating a hydrostatically compensated compressed air energy storage system in a first charging mode including conveying the compressed air at a nearly constant first operating pressure which displaces a corresponding volume of compensation liquid from the layer of compensation liquid out of the accumulator, and a second charging mode including conveying additional compressed air into the accumulator while compensation liquid is not displaced from within the accumulator so that the pressure of the layer of compressed air increases to a second operating pressure that is greater than the first operating pressure.

Abstract: A hydrostatically compensated compressed air energy storage system may include an accumulator disposed underground, a gas compressor/expander subsystem in fluid communication with the accumulator interior via an air flow path; a compensation liquid reservoir spaced apart from the accumulator and in fluid communication with the layer of compensation liquid within the accumulator via a compensation liquid flow path; and a first construction shaft extending from the surface of the ground to the accumulator and being sized and configured to i) accommodate the passage of a construction apparatus therethrough when the hydrostatically compensated compressed air energy storage system is being constructed, and ii) to provide at least a portion of one of the air flow path and the compensation liquid flow path when the hydrostatically compensated compressed air energy storage system is in use.
