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.
Note that other categorizations of energy storage types have also been used such as electrical energy storage vs thermal energy storage, and chemical vs mechanical energy storage types, including pumped hydro, flywheel and compressed air energy storage. Fig. 10. A classification of energy storage types. 3. Applications of energy storage
For example, some reviews focus only on energy storage types for a given application such as those for utility applications. Other reviews focus only on electrical energy storage systems without reporting thermal energy storage types or hydrogen energy systems and vice versa.
Electrical storage systems are particularly well-suited to roles that demand rapid energy deployment. In the realm of power grids, they are used to perform tasks such as frequency regulation, which helps to maintain the balance between the grid’s supply and demand by quickly absorbing or releasing energy.
Mechanical storage encompasses systems that store energy power in the forms of kinetic or potential energy such as flywheels, which store rotational energy, and compressed air energy storage systems. Another emerging option within mechanical storage is gravitational energy storage, which is currently under development.
Zakeri and Syri also report that the most cost-efficient energy storage systems are pumped hydro and compressed air energy systems for bulk energy storage, and flywheels for power quality and frequency regulation applications.
