In various embodiments, compressed-gas energy storage and recovery systems feature one or more valves, which may be disposed within end caps of cylinder assemblies in which gas is expanded and/or compressed, for admitting fluid to and/or exhausting fluid from the cylinder assembly.

Fluid-flow control in energy storage and recovery systems

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

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.
