What are the new pumped storage methods

Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing.A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used. Basic principleA pumped-storage hydroelectricity generally consists of two water reservoirs at different heights, connected with each other.At times of low electrical demand, excess generation capacity is used to pump water into the up.
