Abstract
A system for generating power is disclosed. The system comprises a first storage reservoir for a first liquid fluid and a second storage reservoir for a second higher density fluid located at a lower elevation. Power is generated using a pump, a generator, and fluid displacement.
Claims30
A system for storing and generating power comprising:
- 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;
- a pump;
- a generator;
- and
- a pressure exchanger to pressure exchange between the second fluid and the first fluid such that the pressure inside the second reservoir is within 10 percent of the pressure of an adjacent body of water at the same elevation;
- wherein the pump, the generator, and the first and the second reservoir are operatively connected such that power is stored by displacing the first fluid in the first storage reservoir by pumping the second fluid in the second storage reservoir to the first storage reservoir and power is generated or discharged by allowing the second fluid in the first storage reservoir to return to the second storage reservoir;
- and
- wherein the first fluid is a liquid.
