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).
A typical CSP plant consists of: i) mirrors to redirect DNI to an absorber ii) a system of heat transfer to convey the captured heat to a power cycle, iii) system of thermal energy storage to maintain the energy supply throughout a 24 h day, and optionally iv) back-up system to aid the control of electricity generation [1], [7], [9].
