The form of converted energy widely determines the classification of energy storage systems [4]. ESS's may be divided into 5 main categories such as chemical, electrochemical, electrical, mechanical, and thermal energy storage [5]. . Special report on energy storage powe decarbonization while maintaining reliability. Furthermore, energy storage systems can be classified based on several criteria, such as the type of stored energy, the technology employed, their. . A battery energy storage system (BESS) or battery storage power station is a type of energy storage technology that uses a group of batteries to store electrical energy. Sensible liquid storage includes aquifer TES, hot water ES, gravel-water TES, cavern TES, and molten-salt TES.
