Energy is available in different forms such as kinetic, lateral heat, gravitation potential, chemical, electricity and radiation. Energy storage is a process in which energy can be transformed from forms in which it is difficult to store to the forms that are comparatively easier to use or store. The global energy demand is increasing and with time the available natural

There are several types of thermal energy storage devices, including molten salt, ice storage systems, hot water tanks and aquifer thermal energy storage (ATES) systems, which use temperature (entropy) to store energy. In many cases, excess heat is stored in thermally conductive materials and then retrieved to generate electricity.
There are three main types of MES systems for mechanical energy storage: pumped hydro energy storage (PHES), compressed air energy storage (CAES), and flywheel energy storage (FES). Each system uses a different method to store energy, such as PHES to store energy in the case of GES, to store energy in the case of gravity energy stock, to store

Storing water was the first way to store potential energy that can then be converted into electricity. Pumped-storage hydroelectric plants are very important for electrical systems, as they accumulate energy in periods where the demand is low and give back the energy stored once the demand increases.
