Energy storage technologies available for large-scale applications can be divided into four types: mechanical, electrical, chemical, and electrochemical ( 3 ). Pumped hydroelectric systems account for 99% of a worldwide storage capacity of 127,000 MW of discharge power. Compressed air storage is a distant second at 440 MW.
