Energy storage systems are crucial for improving the flexibility, efficiency, and reliability of the electrical grid. . Grid energy storage, also known as large-scale energy storage, is a set of technologies connected to the electrical power grid that store energy for later use. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources. . The electricity supply chain consists of three primary segments: generation, where electricity is produced; transmission, which moves power over long distances via high-voltage power lines; and distribution, which moves power over shorter distances to end users (homes, businesses, industrial sites. . Energy storage systems are crucial for improving the flexibility, efficiency, and reliability of the electrical grid. There are many sources of flexibility and grid services: energy storage is a particularly versatile one. Various types of energy storage technologies exist. . However, for widespread deployment of grid energy storage to occur, the research community must continue to investigate and improve ultra-low-cost materials and chemistries capable of long-term deployment.
