Title: Hybrid compressed air/water energy storage system and method

Abstract

A hybrid compressed air/water energy storage system is described. The system includes a series of water containers and a plurality of inflatable bladders held within each container. An air compression facility is used to inflate the bladders upon which water is forced out of the containers to a water storage facility at a higher potential energy. The system includes a water powered turbine and an expansion turbine. Thus, the system can produce power from both the water powered turbine (e.g., as a component of a hydroelectric plant) and from the expansion turbine (e.g., as a component of a CAES plant). The system can be utilized in a subsurface land-based system or a submerged water-based system.
