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.

TL;DR: In this paper, the authors describe a system 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 circuits.

TL;DR: In this article, 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 system and the source of thermal energy.

TL;DR: In this article, the authors proposed a staged pneumatic conversion system for providing narrow pressure ranges to a hydraulic motor. But their work was focused on power generation and energy storage and recovery.

TL;DR: In this paper, pneumatic cylinder assemblies are coupled in series pneumatically, thereby reducing a range of force produced by or acting on the PNEU assemblies during expansion or compression of a gas.
