Abstract
[Introduction]Global climate change and its negative impacts are serious humanitarian challenges.Accelerating the construction of a new energy system and promoting energy transition to green and low-carbon are the key to addressing the above challenge.Building a new power system is the central link in planning and constructing a new energy system.[Method]The characteristics and challenges in the six stages of constructing a new power system with new energy source as the main body,and potential roles of energy storage were described and analyzed.The viewpoint that energy storage,especially long-term energy storage,is a key technology for building a new power system was proposed.[Result]To deal with vague concept,unclear technical system and undefined R&D system for long duration energy storage in China,by analyzing the international use cases,the concept system of long-duration energy storage and its technology system covering four categories(including mechanical energy storage,thermal storage,electrochemical energy storage,and chemical energy storage)are proposed.And the R&D trends in developed countries are shown.[Conclusion]It is expected that the relevant content can provide reference for the research and application of long duration energy storage in China.
