A review of pumped hydro energy storage

In pumped hydroelectricity storage systems, the turbine can become a pump: instead of the generator producing electricity, electricity can be supplied to the generator which causes the generator and turbine to spin in the reverse direction and pump water from a lower to an upper reservoir. Sometimes the pump and the turbine are separate items

Pumped Storage Hydro

Pumped storage hydro (PSH) must have a central role within the future net zero grid. No single technology on its own can deliver everything we need from energy storage, but no other mature technology can fulfil the role that pumped storage needs to play. It is a mature, cost-effective energy-storage technology capable of delivering storage
