A review of pumped hydro energy storage

The capital cost of an energy storage system has two components: an energy cost ($ GWh −1) and a power cost ($ GW −1). Sometimes these components are conflated into a single number (e.g. $ GW −1) by using a fixed storage time such as 6 h. This can sometimes be useful when comparing similar systems but is misleading when comparing
