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

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