Utility
Compressed Gas Energy Storage System
19 Oct 23
A compressed air energy storage system may have an accumulator and a thermal storage subsystem having a cold storage chamber for containing a supply of granular heat transfer, a hot storage chamber and at least a first mixing chamber in the gas flow path and having an interior in which the compressed gas contacts the granular heat transfer particles at a mixing pressure that is greater than the cold storage pressure and the hot storage pressure and a conveying system operable to selectably move the granular heat transfer particles from the cold storage chamber, through the first mixing chamber and into the hot storage chamber, and vice versa.

Utility
Reversible Heat Exchangers In Compressed Air Energy Storage Systems
13 Apr 23
A method of processing a stream of compressed air travelling between a gas compressor/expander subsystem and an underground accumulator in a compressed air energy storage system may include directing a thermal storage liquid through the first liquid flow path in a liquid charging flow direction from a thermal source reservoir toward a thermal storage reservoir whereby at least a portion of the thermal energy in the compressed air is transferred from the compressed air into the thermal storage liquid within the first reversible heat exchanger; including redirecting the compressed air through the first gas flow path in a gas discharging flow direction that is opposite the gas charging flow direction and redirecting the thermal storage liquid through the first liquid flow path in a liquid discharging flow direction whereby at least a portion of the thermal energy in the thermal storage liquid is returned into the compressed air.

Three Section Configuration for Compressed Air Energy Storage Systems
23 Jun 22
A method of temporarily storing thermal energy via a thermal storage subsystem in a compressed air energy storage system comprising an accumulator disposed at least 300 m underground and having an interior configured to contain compressed air at an accumulator pressure that is at least 20 bar and a gas compressor/expander subsystem in communication with the accumulator via an air flow path for conveying compressed air to the accumulator when in a charging mode and from the accumulator when in a discharging mode.
