Technologies covered

Electrochemical energy storage: Electricity stored in batteries via electrochemical reactions, currently dominated by lithium-ion technology, with other types including lead-acid, flow, and sodium-ion batteries.

Mechanical energy storage: Energy stored in mechanical form, almost entirely provided by pumped-storage hydropower, with CAES representing a small share.

Thermal energy storage: Energy stored as heat and released later for electricity generation or heat supply, typically using molten salt, hot water, or phase-change materials.

Chemical energy storage: Energy storage through the conversion of electricity to hydrogen.
