In various embodiments, compressed-gas energy storage and recovery systems include a cylinder assembly for compression and/or expansion of gas, a reservoir for storage and/or supply of compressed gas, and a system for thermally conditioning gas within the reservoir.

Heat exchange with compressed gas in energy-storage systems

The invention relates to systems and methods for rapidly and isothermally expanding and compressing gas in energy storage and recovery systems that use open-air hydraulic-pneumatic cylinder assemblies, such as an accumulator and an intensifier in communication with a high-pressure gas storage reservoir on a gas-side of the circuits and a combination fluid motor/pump, coupled to a combination electric generator/motor on the fluid side of the circuits. The systems use heat transfer subsystems in communication with at least one of the cylinder assemblies or reservoir to thermally condition the gas being expanded or compressed.

Systems and methods for energy storage and recovery using rapid isothermal gas expansion and compression

In various embodiments, dead space and associated coupling losses are reduced in energy storage and recovery systems employing compressed air.

Systems and methods for reducing dead volume in compressed-gas energy storage systems

In various embodiments, efficiency of energy storage and recovery systems compressing and expanding gas is improved via heat exchange between the gas and a heat-transfer fluid.

Forming liquid sprays in compressed-gas energy storage systems for effective heat exchange

In various embodiments, cylinder assemblies are coupled in series pneumatically, thereby reducing a range of force produced by or acting on the cylinder assemblies during expansion or compression of a gas.

Energy storage and generation systems and methods using coupled cylinder assemblies

The invention relates to systems and methods including an energy conversion system for storage and recovery of energy using compressed gas, a source of recovered thermal energy, and a heat-exchange subsystem in fluid communication with the energy conversion system and the source of recovered thermal energy.

Systems and methods for combined thermal and compressed gas energy conversion systems

In various embodiments, dead space and associated coupling losses are reduced in energy storage and recovery systems employing compressed air via use of a compressed-gas reservoir for maintaining a connector between cylinder assemblies at an intermediate pressure, thereby reducing the volume of dead space in the connector and increasing efficiency of the energy storage and recovery.

In various embodiments, pneumatic cylinder assemblies are coupled in series pneumatically, thereby reducing a range of force produced by or acting on the pneumatic cylinder assemblies during expansion or compression of a gas.
