Worldwide grid-scale battery electricity storage system capacity was 55.7GW in 2023
Energy storage provides the flexibility to supply energy when needed, using various forms such as chemical, kinetic, thermal, and gravitational potential. The choice of storage depends on location and reserve service, as different technologies offer varying capacities and durations. Traditional fuel storage has long been common, but integrating intermittent renewable sources necessitates energy storage for a resilient, low-carbon network. Strategically placed storage can prevent costly network upgrades and enhance grid security through interconnection. Applications range from small-scale systems in homes to utility-scale storage. Examples include lithium-ion batteries, pumped hydroelectric storage, and ice storage tanks. Surplus renewable electricity can produce hydrogen for long-term storage, and electric vehicles can also serve as storage systems. As energy storage becomes crucial for a sustainable future, evaluating technologies for cost, efficiency, material sustainability, and safety is essential.
