On June 7, 2024, at the annual conference of the China New Energy Storage Industry Innovation Alliance, the Electric Power Planning and Design Institute released the "China New Energy Storage Development Report 2024" (hereinafter referred to as the "Report"), which pointed out that from the perspective of the power supply and demand situation and the future development of conventional power sources, strengthening the power supply system is a key task in building a new power system, and new energy storage will become an important supplement to the construction of the power supply guarantee support system. From a technical perspective, it is expected that long-term energy storage with a storage time of 4 hours or more will become the main force in the development of the energy storage industry in the future.
Wang Chengshan, an academician of the CAE Member and vice chairman of the expert committee of the China New Energy Storage Industry Alliance, said that in the past year, China's new energy storage industry has flourished, the trend of technological diversification is obvious, policy support has been strengthened, and the ability to support the construction of new power systems has been constantly enhanced.
The report shows that as of the end of 2023, the cumulative installed capacity of new energy storage projects in China has reached 31.39 million kilowatts/6688 million kilowatt hours, with an average energy storage time of 2.1 hours, nearly 10 times the final installed capacity of the 13th Five Year Plan. The installed capacity of new energy storage projects has completed the planned target two years ahead of schedule. Among them, the newly installed capacity for the whole year of 2023 was about 22.7 million kilowatts/48.78 million kilowatt hours, an increase of about 260% compared to the end of 2022. It is expected that by the end of the 14th Five Year Plan and the 15th Five Year Plan period, new energy storage can become an important means to cope with the large-scale grid connection and consumption of new energy with advantages such as short construction period, flexible layout, and strong transient regulation ability.
The planning, construction, and layout of new energy storage will be more scientific and reasonable. The report states that in the future, new energy storage on the power side will rely on existing resources and the addition of cross regional channels and integrated multi energy complementary bases for wind, solar, water, and thermal storage during the 14th Five Year Plan period; The new type of energy storage on the power grid side can be reasonably allocated in key nodes of the power grid, remote areas, and areas with limited resources of transmission and transformation stations, improving the system's regulation capacity and moderately replacing transmission and transformation facilities; User side energy storage promotes the construction of decentralized energy storage facilities on the user side, explores bidirectional interactive intelligent charging and discharging technologies such as V2G and smart electricity facilities, and improves the reliability of user power supply and the flexibility of user side regulation.
From the perspective of technological roadmap, the country has issued clear policies that future innovation in new energy storage technologies will develop towards high safety, large capacity, low cost, and long lifespan, while also focusing on tackling long-term energy storage technologies. Various regions have also introduced relevant guiding support policies, including promoting the pilot application of long-term energy storage, increasing support for capacity leasing and compensation, and supporting participation in the spot market. In January 2024, the National Energy Administration announced a new batch of new energy storage pilot demonstration projects. From a technical perspective, the number of long-term energy storage technology projects represented by compressed air and liquid flow batteries exceeds the current mainstream lithium-ion battery projects. It is expected that long-term energy storage with a storage time of 4 hours or more will become the main force in the development of the energy storage industry in the future.
Song Hailiang, Secretary of the Party Committee, Chairman, and Chairman of the Alliance of China Energy Construction Group Co., Ltd., proposed an initiative: "Strengthen innovation drive, continuously promote the iteration and upgrading of new energy storage technologies, focus on technology research and development, product innovation, and industry incubation, provide talent guarantee for continuous technological progress; strengthen green and low-carbon, continuously promote the construction of green and environmentally friendly energy storage systems, promote the establishment of green energy storage standard systems, strengthen certification and promotion of green energy storage projects, stimulate more green technology innovation and application; strengthen digital intelligence, improve the integration and operation efficiency of new energy storage systems, and promote the upgrading and upgrading of the energy storage industry to digitalization and intelligence; strengthen sharing and integration, enhance the sharing of information, technology, products, services, and management among enterprises, and improve the implementation of new energy storage projects."
