Compressed air energy storage system utilizing two-phase flow to facilitate heat exchange
TL;DR: In this paper, a reversible air compressor-expander uses mechanical power to compress air and converts the energy stored in compressed air to mechanical power when it is acting as an expander.
Patent
Systems and methods for energy storage and recovery using compressed gas
TL;DR: In this article, the authors describe methods and systems for the storage and recovery of energy using open-air hydraulic-pneumatic accumulator and intensifier arrangements that combine at least one accumulator with at least two intensifiers 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.

System, method and computer program product for enhancing commercial value of electrical power produced from a renewable energy power production facility
TL;DR: In this article, the authors proposed a virtual energy storage mechanism for supplementing an output power of a wind turbine generation facility when lull periods for wind speed appear, where the wind turbine power production facility experiences a shortfall in its power production output it may make a request to the other source of electric power, and request that an increase its power output on behalf of the turbine facility.
