Pumped hydro storage plants are energy storage solutions that consist of two water reservoirs, a tunnel connecting the lower and an upper reservoir and a powerhouse with a pump/turbine. In the 1990s, after the fall of the Soviet Union, the rapid rise in installed capacity of PHS plants stopped mainly due to cheap and high availability

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. The method 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 to run the

A new form of PSH, called Ground-Level Integrated Diverse Energy Storage (GLIDES) systems, pumps water into vessels full of air or other pressurized gases. As more water fills the vessel, it compresses the gases. When the grid needs electricity, a valve opens and the pressurized gas pushes the water through a turbine, which spins a
