Abstract: Efficient and economic energy storage, if implemented in the current power infrastructure on a large scale, could bring about some of the greatest changes in the power industry in decades. Additionally, energy storage would improve the reliability and dynamic stability of the power system by providing stable, abundant energy reserves that require little ramp time and are less susceptible to varying fuel prices or shortages. Energy storage can shift the higher peak load to off-peak hours in order to level the generation requirement, allowing generators to run more efficiently at a stable power level, potentially decreasing the average cost of electricity. Additionally, increased energy storage capacity can avoid generation capacity, decrease transmission congestion, and help enable distributed generation such as residential solar and wind systems. In this paper energy storage methods are discussed in such a way to provide a detailed overview of how each of the energy storage devices work so that the reader is able to get a better feel for the potential benefits and drawbacks of each device.
