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).
Concentrated solar power (CSP) is a system that collects solar energy using mirrors or lenses and uses the concentrated sunlight to heat a fluid to run a turbine and generate electricity.
