Abstract: With an increased pace in energy transition, high penetration of renewables in the power grid is becoming an inevitable trend. Advanced energy storage is one of the important methods to facilitate the integration of renewables to the power grids. This paper focuses on energy storage technologies for power grid-scale applications. Various energy storage technologies are analyzed first. The technical characteristics of these technologies are then analyzed together with their economic aspects. This is followed by expert interviews and surveys. Finally, a roadmap is proposed on the basis of these outputs for large scale energy storage in China for 2020, 2030 and after 2030, including the expected scale, technical development and economic features of these energy storage technologies.
