Underground Pumped hydro storage
Similar to conventional hydro storage on the surface, underground pumped hydro storage has upper and lower water reservoirs, a machine cavern with electrical facilities as well as supply and dissipation lines to the electrical grid. In contrast to conventional pumped hydro storage the constructions are predominately located in the subsurface.

A review of pumped hydro energy storage
Pumped hydro energy storage (PHES) comprises about 96% of global storage power capacity and 99% of global storage energy volume. Batteries occupy most of the balance of the electricity storage market including utility, home and electric vehicle batteries. Batteries are rapidly falling in price and can compete with pumped hydro for short-term storage (minutes to …
