Energy storage
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery.Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent …

Pumped Hydroelectric Storage: Making Renewable Energy Sources Reliable
Pumped hydroelectric energy storage takes proven hydroelectric energy generation technology and runs the process in reverse to store energy. Excess energy is used to pump water uphill, and when demand exceeds supply the water is allowed to flow back downhill, turning turbines to generate electricity as it does so. Most facilities involve a ...

Pump Up the Storage | Do the Math
The idea for pumped hydro storage is that we can pump a mass of water up into a reservoir (shelf), and later retrieve this energy at will—barring evaporative loss. Pumps and turbines (often implemented as the same physical unit, actually) can be something like 90% efficient, so the round-trip storage comes at only modest cost.
