Electrical Energy Storage is a process of converting electrical energy into a form that can be stored for converting back to electrical energy when needed (McLarnon and Cairns, 1989; Ibrahim et al., 2008 ). In this section, a technical comparison between the different types of energy storage systems is carried out.
Executive summary. 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. In the near future EES will become indispensable in emerging IEC-relevant
A flywheel is a mechanical device. It rotates and stores energy. First, electrical energy is used to make it spin. The spinning creates kinetic energy. Then the electrical energy gets turned off. But because of inertia, the flywheel will keep spinning. Later, you can turn the kinetic energy back into electrical energy.
In September 2017, it was reported that worldwide electrical energy storage amounted to 176 GW, which is less than 2% of the world''s electric power production capacity. In the US, 24 GW of electrical power was obtained from stored electricity (about 2.2% of U.S. production capacity and most of that came from pumped
Storing 1,000 GWh would mean storing 2,000 GL of water all with a head of 200 m (see Sect. E.3 in Appendix E—Energy Storage). To give us an idea of what 2,000 GL of storage means, Melbourne in Australia has a population of just under 4 million and a total water storage capacity of 1,800 GL.
Temperatures can be hottest during these times, and people who work daytime hours get home and begin using electricity to cool their homes, cook, and run appliances. Storage helps solar contribute to the electricity supply even when the sun isn''t shining. It can also help smooth out variations in how solar energy flows on the grid.
One way of ensuring continuous and sufficient access to electricity is to store energy when it is in surplus and feed it into the grid when there is an extra need for electricity. EES

Housed in a giant warehouse, the 1,300-metric ton battery is larger than a football field, and can crank out 40 million watts of power. Still, the Fairbanks battery provides only enough electricity for about 12,000 residents for seven minutes. That was enough to prevent 81 blackouts in the city in the battery''s first two years of operation.
Storage can be installed at different stages in the electricity system and might serve a number of different purposes: at the upstream level, storage can integrate

3. Types of storage and recent developments. Storage has played an important role in balancing electricity supply and demand since the beginning of electricity systems. Depending on the characteristics of a specific type of electricity storage, it can be used for different purposes and provides various services.
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.
