energy storage may be able to retain vastly greater quantities of energy over much longer durations compared to typical bat-tery storage. Geologic energy storage also has high flexibility; many different types of materials can be used to store chemi-cal, thermal, or mechanical energy in a variety of underground settings.
Energy storage systems are then required to deal with this intermittency as they provide flexibility by shifting the load demand temporally [7, 8]. ... PSH store electricity by moving water between an upper and lower reservoir. Electric energy is converted to potential energy and stored in the form of water at an upper elevation.
Energy storage has become the primary enabling technology to further implementsolar and wind electric power generation worldwide (Agarwal and Giberti 2020, Morgan 2020). Recent research has shown the potential of reservoir thermal energy storage ("RTES") for deep subsurface storage of water at high temperature; 250°C, for example.
Pumped hydroelectric energy storage stores energy in the form of potential energy of water that is pumped from a lower reservoir to a higher level reservoir.
