The other storage alternative is the well-advanced pumped-storage technology. Two reservoirs at two different altitudes will act as a battery. The excess of energy will be converted into mechanical energy via a pump and used to transfer the water from the lower reservoir towards the upper one, thus giving the water potential energy.
Among the drivers, pumped hydro storage as daily storage (TED2.1), under the utility-scale storage cluster, was the most important driver, with a global weight of 0.148. Pumped hydro's ability to generate revenue (SED1.1), under the energy arbitrage cluster, was the second most prominent driver, with a global weight of 0.096.
