| description | A compressed air pumped hydro energy storage and distribution system includes a first reservoir of water and a second reservoir of air and water. An air pressure source, connected to the second reservoir, develops a pressure head in the second reservoir. A pump/turbine-motor/generator, received by the first reservoir, is connected to a regional energy grid. During peak demand periods, the pressure head forces water through the pump/turbine-motor/generator to generate power, delivered to the grid. During low demand periods, the pump/turbine-motor/generator pumps water back to the second reservoir, regenerating the pressure head. A third air reservoir interconnected with the second reservoir and a gas turbine generator can be used to generate power during peak demand periods. The reservoirs can be tunnels or abandoned mines, reinforced and sealed by pressure grouting and/or an internal liner, maintained well beneath the earth's surface and intersecting the path of the grid. |
