Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).

What Is Energy Storage & How Does It Work? | Constellation
Energy storage is growing in importance in our green energy future. Renewable energy is often intermittent, meaning that it must be stored when it''s produced for use later when it is needed. Advances in energy storage may reduce the cost of electricity and the carbon footprint of energy production.
Thermal Energy Storage. In thermodynamics, internal energy (also called the thermal energy) is defined as the energy associated with microscopic forms of energy. It is an extensive quantity, it depends on the size of the system, or on the amount of substance it contains. The SI unit of internal energy is the joule (J).
