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.
Mechanical energy storage systems, including PHS, CAES and flywheels, normally have high cycling times (around 10,000 or more) which mainly depend on their mechanical components. The cycle times for EES with energy stored in electrical energy, such as SMES, capacitors and supercapacitors, are normally higher than 20,000.
In the electricity market, global and continuing goals are CO 2 reduction and more effi cient and reliable electricity supply and use. The IEC is convinced that electrical energy storage will be indispensable to reaching these public policy goals.
Electricity is used to compress air and store it in either an underground structure or an above-ground system of vessels or pipes. When needed the compressed air is mixed with natural gas, burned and expanded in a modifi ed gas turbine. Typical underground storage options are caverns, aquifers or abandoned mines.
The overall cost and the levelised cost of energy storage are given per unit of energy (USD / kWh) as the ratio of all costs incurred for storing the energy (capital, operation and energy costs, if any) to the total amount of energy stored in all storage cycles over the plant’s lifetime.
