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.
There are five types of Energy Storage: Thermal storage can be defined as the process of storing thermal energy storage. The process of storing thermal energy is to continuously heat and cool down the container (in which we are storing thermal energy). And further, we can use this thermal energy later on from this container.
The effectiveness of an energy storage facility is determined by how quickly it can react to changes in demand, the rate of energy lost in the storage process, its overall energy storage capacity, and how quickly it can be recharged. Energy storage is not new.
Hydropower, a mechanical energy storage method, is the most widely adopted mechanical energy storage, and has been in use for centuries. Large hydropower dams have been energy storage sites for more than one hundred years.
Table 2. Examples of current energy storage systems in operation or under development. Consists of two large reservoirs with 385 m difference in height, a power house and the tunnels that connect them. At high demand, water is passed through the tunnel at a rate of up to 852 m 3 /s to drive six generators .
Energy storage solutions for electricity generation include pumped-hydro storage, batteries, flywheels, compressed-air energy storage, hydrogen storage and thermal energy storage components. The ability to store energy can facilitate the integration of clean energy and renewable energy into power grids and real-world, everyday use.

Energy storage methods have three sequential operational periods, which are charging, storing, and discharging periods, as shown in Fig. 2.4. In the charging period, the incoming energy is charged into the energy storage medium which is used for storing energy in it. In the charging period, the energy source may be converted into another energy form. …
