Future energy storage solutions will put more wind and solar on the grid. Battery storage may be considered an old technology. More creative solutions are needed in the renewable energy market. Pumped Hydroelectric energy storage is one example somewhat common.
Pumped-storage hydroelectricity, or pumped hydroelectric energy storage, is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.
Importantly, pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, wind) and other renewables, to be saved for periods of higher demand. The wind doesn’t always blow and the sun doesn’t always shine. New energy-storage technologies will definitely help bypass those limitations.
