A Review of Energy Storage Technologies Comparison and Future Challenges

The goal of the study presented is to highlight and present different technologies used for storage of energy and how can be applied in future implications. Various energy storage (ES) systems including mechanical, electrochemical and thermal system storage are discussed. Major aspects of these technologies such as the round-trip efficiency, installation costs, advantages and disadvantages of its one, environmental footprints, are briefly analyzed as well. Other ES technologies are also discussed such as hydro, pump hydroelectric and thermal ES. Finally, not only the recent research is presented but also the present status and the future development of storage as well as the future challenges are included throughout.
