Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms. Some technologies provide short-term energy storage, while others can endure for much longer. Bulk energy storage is currently dominated by hydroelectric dams, both conventional as well as pumped.
Electrical Energy Storage, EES, is one of the key technologies in the areas covered by the IEC. EES techniques have shown unique capabilities in coping with some critical characteristics of electricity, for example hourly variations in demand and price.
Potential energy storage includespumped hydro storage (PHS) and compressed air energy storage (CAES). o PHS is based on pumping water from a lower reservoir to another at a higher elevation at low-demand period. When demand hits the peak, the collected water is discharged to the bottom reservoir through a turbine to re-produce electricity.
Then the development problems and challenges of these physical energy storage technologies are confirmed, and corresponding recommendations are put forward.
