A New Approach to Pumped Storage Hydropower
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 (discharge) as water moves down through a turbine; this draws power as it pumps water (recharge) to the upper reservoir. PSH capabilities can be characterized as open

Pumped storage provides energy storage at a higher efficiency than most methods. The concept uses two reservoirs connected by a pipeline. When energy costs are low, fluid is pumped to a reservoir at a higher elevation. When energy costs are high, fluid is drained to the lower reservoir through a turbine. The turbine converts the fluid energy
