compressed air energy storage (CAES) are the main components of the non-PHS energy storage capacity. Figure 1: Worldwide installed energy storage capacity Several forecasts predict that in most key markets the overall installations and market for energy storage will increase significantly in the coming years. For example, in the United States a nine-fold growth of the market over the next five years across all segments of energy storage is expected, which would result in 2 GW of new installations by 2021. Energy Storage Applications – Electricity Sector Figure 2 shows that, in addition to RES integration and arbitrage, there is a wide range of potential energy storage applications at all levels ranging from energy generation, transmission, and distribution up to the customer or load site. Each application is described below.
