   Energy storage has become a requirement to help convert intermittent energy sources such as wind and solar into firm power. [21] Other energy storage solutions, such as pumped hydroelectric storage, dominate the time-shift market. As of 2019, pumped hydroelectric storage accounted for 96% of global energy storage capacity. [22]
