On October 11, 2017, five key Chinese government agencies—the National Development and Reform Commission, the Ministry of Finance, the Ministry of Science and Technology, the Ministry of Industry and Information Technology, and the National Energy Administration—jointly released the "Guiding Opinions on Promoting China's Energy Storage Technology and Industrial Development." This was the first comprehensive policy document aimed at accelerating the growth of China’s energy storage sector. The guiding opinions addressed critical challenges such as insufficient policy support, limited research and development (R&D), lack of technical standards, and inadequate overall planning in the development of energy storage technologies. They emphasized the growing importance of energy storage in smart grids, high-penetration renewable energy systems, and the emerging energy internet. By setting clear goals for the next decade, this policy marked a significant milestone in shaping China’s energy future.
Supported by the National Energy Administration, the Zhongguancun Energy Storage Industry Technology Alliance collaborated with leading research institutes, including the Institute of Engineering Thermophysics of the Chinese Academy of Sciences and the China Academy of Electric Power, to develop the "Guiding Opinions." This article explores the implications of these guidelines, drawing from the alliance’s extensive research and data collected over the years. It highlights how the policy aims to accelerate the commercialization of energy storage technologies and drive sustainable industry growth.
1. Diverse Energy Storage Technologies Are Gaining Momentum
Over the past few years, the value of energy storage in supporting renewable energy integration and improving grid stability has become increasingly evident. As a result, governments, companies, and researchers have intensified their efforts in R&D, demonstration projects, and technology deployment. Advanced energy storage solutions, such as compressed air, flywheel, lead-acid, lithium-ion, sodium-sulfur, and flow batteries, are maturing rapidly. Their performance is improving, costs are dropping, and system integration capabilities are strengthening. Meanwhile, new technologies like thermal storage, cold storage, and hydrogen storage are also being explored. These innovations are moving beyond laboratories and entering commercial applications, creating a vibrant ecosystem of energy storage options.
According to the Zhongguancun Energy Storage Industry Technology Alliance (CNESA), by the end of 2016, China had approximately 24.3 GW of installed energy storage capacity, with pumped hydro accounting for nearly 99%. Electrochemical storage, however, showed rapid growth, reaching 243 MW with an annual increase of over 72%. Lithium-ion batteries dominated the market, followed by lead batteries, flow batteries, and supercapacitors. Looking ahead, the "Guiding Opinions" aim to promote the industrialization of multiple energy storage technologies, ensuring they can coexist and complement each other in various applications.
2. Energy Storage Applications Are Becoming More Defined
As the need for renewable energy integration and grid modernization grows, energy storage applications are becoming more clear-cut. The policy emphasizes the importance of designing effective mechanisms and conducting pilot projects to enhance the real-world impact of energy storage. User-side energy storage, large-scale renewable energy storage, and participation in ancillary services are now key areas of focus. For instance, industrial and commercial parks are using energy storage to manage electricity tariffs, while renewable energy projects are exploring large-scale storage solutions to address intermittency issues.
The Shijingshan Thermal Power Plant’s frequency modulation project, launched in 2013, marked an early step in China’s energy storage commercialization. In 2016, the policy encouraged further participation in ancillary services, opening up new opportunities for energy storage providers. With continued investment in pilot projects and improved regulatory frameworks, energy storage is expected to play a central role in optimizing grid operations, enhancing system flexibility, and supporting the energy transition.
3. Market Mechanisms Are Key to Commercialization
China’s energy storage industry is transitioning from demonstration projects to commercial viability. However, economic and profitability challenges remain significant barriers. Many projects face difficulties such as high initial costs, limited revenue streams, and unclear market access. To overcome these obstacles, the "Guiding Opinions" advocate for market-based solutions that allow energy storage to compete fairly in electricity markets, participate in ancillary services, and gain value through multiple applications.
By learning from international examples, such as the U.S. PJM market and the UK’s capacity auctions, China is working to establish a fair and transparent electricity market. This includes enabling energy storage to act as independent entities, participating in power trading, and receiving compensation based on their contributions. Such measures will not only boost investor confidence but also ensure long-term sustainability for the energy storage sector.
4. Standardization and Sustainability Are Critical
As energy storage projects scale up, the need for standardized project management, grid connection protocols, safety regulations, and recycling systems becomes more urgent. The "Guiding Opinions" emphasize the importance of establishing robust frameworks to support the industry’s growth. For example, a producer responsibility system for battery recycling is proposed, along with comprehensive testing and certification processes. These steps will help ensure the safe, efficient, and environmentally friendly deployment of energy storage technologies.
5. Conclusion
With China entering the “13th Five-Year Plan†period, the energy sector is undergoing a transformation driven by innovation and sustainability. Energy storage plays a vital role in this process, enabling better renewable energy integration, enhancing grid flexibility, and promoting intelligent energy management. As awareness of its benefits grows, the industry is poised for rapid expansion. The release of the "Guiding Opinions" marks a crucial step toward overcoming existing challenges and fostering a healthy, sustainable energy storage ecosystem. By addressing market mechanisms, technological development, and environmental considerations, China is well-positioned to lead the global energy storage revolution.
