Today, several factors are converging to enable the growth of grid-connected utility-scale energy storage markets. Battery energy storage solutions and energy storage system (ESS) components have demonstrated that value can be delivered by energy storage technology on the grid. Regional transmission and distribution (TAndD) system organization and power market regulators have recognized these technology advances and are enacting new rules to allow battery ESSs to participate in power markets. Meanwhile, new business models and associated financing instruments are coming together to invest capital in battery energy storage projects. The emergence of a new generation of advanced batteries that are safe, low cost, and efficient enough to allow for storage on the grid is instrumental to the further development of these global markets. Lithium ion (Li-ion) batteries have emerged as the leader in utility-scale applications of batteries on the grid by offering the best mix of performance specifications for most energy storage applications. Flow batteries have the potential to deliver long-duration energy storage applications at lower costs, while advanced lead-acid batteries have proven to be excellent performers in power-intensive applications. The Asia Pacific region is expected to see the highest growth in advanced batteries for utility-scale applications during the next 10 years, though growth is also forecast to be strong in North America and Western Europe. According to Navigant Research, global revenue for advanced batteries for utility-scale storage is expected to grow from $231.9 million in 2016 to $3.6 billion by 2025. This Navigant Research report analyzes the global market for advanced batteries for utility-scale energy storage. The study examines the strengths and weaknesses of the major battery chemistries and how they match to specific applications. Global market forecasts for energy capacity, power capacity, and revenue, segmented by region, application, chemistry, and subchemistry, extend through 2025.
