摘要： A system for storing and generating power is disclosed. The system comprises a first storage reservoir configured to store a first fluid, a second storage reservoir located at a lower elevation than the first storage reservoir and configured to store a second fluid wherein said second fluid has a higher density than the first fluid, and a pump. The pump and the first and the second reservoir are operatively connected such that power is stored by displacing the second fluid in the second storage reservoir by pumping the first fluid from the first storage reservoir to the second storage reservoir and such that power is generated by allowing the pumped first fluid in the second storage reservoir to exit the second reservoir. The first fluid is generally a liquid. In some embodiments, a power recovery device may be employed. In some embodiments, the hydraulic pressure of the low density fluid may be employed to pressurized desalination feed and facilitate desalination.

摘要： An exemplary power system utilizes turbines configured within a water intake conduit to the desalination processor to produce power for the desalination processor. Water intakes are configured to provide a natural flow of water to the desalination processor though hydrostatic pressure. One or more turbines coupled with the water intake conduits are driven and produce power for the system. The desalination processor incorporates Graphene filters to and may include a structured water system to increase the H3O2 concentration of the water prior to Graphene filters. Discharge water may be pumped back into the body of water but be separated from the intakes. A secondary power source, such as a renewable power source, may be used to produce supplemental power for the system. Power produced may be provided to a secondary outlet, such as a power grid, all above and/or underground.

摘要： A system and method of combining pumped hydro and thermal energy storage is disclosed that has upper and lower fluid storage reservoirs. The reservoirs are used as a pumped energy storage system in which excess electrical power is stored as gravitational potential energy by using it to transfer fluid up to the upper one. At a later time, the fluid is run back down through a turbine under the force of gravity to generate electricity. Either, or both, fluid storage regions are also used to store thermal energy transferred into the stored fluid via liquid-to-liquid heat exchangers. The stored thermal energy is later extracted out to be distributed in for use in either directly heating structures or to improve the heating efficiency of one or more heat pumps in a district heating system. The fluid may be water, or it may be any suitable high-density fluid such as drilling mud.
