The dramatic increase in the price of petroleum, depletion of fossil fuels, the impacts of global warming and health and safety considerations are forcing the search for new energy sources. In this regard, renewable energy resources appear to be one of the most efficient and effective solutions. The extensive use of renewable energy resources can indisputably minimize the threat of global warming and climate change. Today, renewable energy technologies are the fastest growing energy technologies and are cost competitive in a variety of grid, off-grid, and remote applications worldwide. There are numerous renewable energy options including wind, geothermal, solar and several forms of advanced bioenergy. High penetration level of wind power causes serious problems of power grid stability and reliability due to the intermittence and volatility of wind power. Suitable solutions are urgently needed and energy storage has been recognized as one of the most promising technologies for addressing the problems. Recent developments and advances in electrical energy storage technologies (EST) and the application potential in power system operation are making the application of EST a viable solution for modern power applications. Modern EST require much larger amounts of energy to be stored with a high energy density, quickly and at low cost. Energy storage is expected to play a significant role in creating a more flexible and reliable electricity system. EST systems are classified into mechanical, electrochemical, chemical, electrical and thermal energy storage systems. In this work, a comparison between the various technologies is presented in terms of the most important technical and economic characteristics of each technology.Storage of thermal energy in the form of sensible and latent heat has become an important aspect of energy management with the emphasis on efficient use and conservation of the waste heat and solar energy in industry and buildings.
