Abstract
Hydroelectric pumped-storage includes monitoring electrical demand on a system over time. If the monitored demand exceeds a predetermined first value, fluid is allowed to flow substantially under the influence of gravity from a first aquifer to a second aquifer. Kinetic energy from the flowing fluid is converted into electrical energy. If the monitored demand drops below a predetermined second value, fluid from the second aquifer is moved to the first aquifer.

7. A system comprising:
-
a first aquifer; a second aquifer; one or more fluid communication channels that facilitate fluid flow between the first and second aquifers; and a turbine-generator arranged to convert kinetic energy of fluid flowing from the first aquifer to the second aquifer through one or more of the fluid communication channels into electrical energy; wherein at least one of the first or second aquifers is a naturally-occurring underground layer of water-bearing permeable rock or unconsolidated materials. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
