Abstract: An energy storage system has a pressure vessel that is exposed to ambient temperatures and that contains a working fluid which is condensable at ambient temperatures (CWF); a liquid reservoir in communication with one of the vessels and containing a liquid that is unvaporizable in the reservoir and in the vessel; and apparatus for delivering the liquid from the reservoir to the vessel. The CWF is compressible within the vessel upon direct contact with the liquid and is storable in a liquid state after being compressed to its saturation pressure. In a method, at least some of the liquid located in the vessel is propelled by the CWF towards a turbine to produce power. In one embodiment, a module has a first vessel having at least four ports, a second vessel at ambient temperatures, and a flow control component operatively connected to a corresponding conduit for selectively controlling fluid flow.
