Abstract
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.
