Abstract: Energy storage is the convenient and economical storage of energy from a non storable form (kinetic energy, electricity etc) to a storable form of energy. Energy storage is accomplished by using a specific device usually referred to as an accumulator. Storage of energy maintains the equilibrium of supply and demand of energy in the nature. Energy storage can be done for mechanical, electrical, biological as well as chemical and thermal form of energy. Energy storage can be long term as well as short term depending on the type mechanism opted for storing energy.
