It discusses the various energy storage options available, including batteries, flywheels, thermal storage, pumped hydro storage, and many others. . What is energy storage? 57Katriona EdlmannINTRODUCTIONEnergy storage, encompassing the storage not only of electricity but also of energy in various forms such as chemicals, is a linchpin in the movement towards a decarbonized energy sector, due to its myriad roles in fortifying grid reliability. . While en-ergy storage represents only a small percentage of the total number of resources deployed on the electric grid today, the U. Department of Energy has identified the use of energy storage as a potential path to help ensure the future reliability and resiliency of the United States power. . The goal of the DOE Energy Storage Program is to develop advanced energy storage technologies and systems in collaboration with industry, academia, and government institutions that will increase the reliability, performance, and sustainability of electricity generation and transmission in the. . , and advocating for energy efficiency and equity. The paper focuses on energy. .
