Storing Solar Energy in Water with Pumped Hydro Storage

Pumped hydro storage is a well-tested, mature technology capable of releasing large, sustained amounts of energy through water pumping. The process requires two reservoirs of water, one at a low elevation, and the other at a higher elevation. Once connected, low cost electricity (like solar) is used to pump the water from below to above.
