![]() ![]() Since then, they have become the most widely used battery technology for grid-scale energy storage. ![]() Lithium-ion (Li-ion) batteries were introduced commercially by Sony in 1991 for use primarily in consumer products. There are performance-specific features and applications for each of these battery systems, however, the goal of energy storage developers is the same: to choose a battery application that will ensure an affordable, reliable, and efficient energy-storage system. Storage systems may support renewable projects such as wind and solar, by regulating the variability of these energy sources and increasing reliability to deliver on-demand power. Since that time, however, redox-flow and zinc-hybrid ion batteries have emerged as significant technologies in the market.Īlthough utility-scale energy storage installations saw a slight drop in the first three quarters of 2018, the industry is expected to gain momentum this year. One major takeaway from the study stated that lithium-ion batteries accounted for about 95% of deployed systems in the grid-scale battery market. ![]() Such a drastic increase in deployment would, according to estimates, lead to an energy storage market worth $2.8 billion.ĭavid Hart and Alfred Sarkissian of George Mason University studied grid-scale batteries in the United States and reported their findings to the U.S. The study projects that by 2021 deployments of stored energy - a combination of residential, non-residential, and utility systems - will grow to over 2 GW, over 10 times greater than current levels. A typical lithium-ion battery system can store and regulate wind energy for the electric grid.īack in 2017, GTM Research published a report on the state of the U.S. ![]()
