Recently, the National Development and Reform Commission and the Energy Administration issued the Implementation Plan for the Development of New Energy Storage during the 14th Five Year Plan period. The document proposes that by 2025, new energy storage will enter the stage of large-scale development from the initial commercialization stage and have the conditions for large-scale commercial application.

The innovation capability of new energy storage technologies has significantly improved, the level of independent and controllable core technology and equipment has been greatly enhanced, and the standard system has been basically improved. The industrial system is becoming increasingly complete, and the market environment and business models are basically mature. By 2030, the comprehensive market-oriented development of new energy storage will be achieved.

The core technology and equipment of new energy storage are independently controllable, with technological innovation and industrial level ranking among the top in the world. The market mechanism, business model, and standard system are mature and sound, deeply integrated with various links of the power system for development, basically meeting the needs of building a new power system, and comprehensively supporting the achievement of carbon peak goals in the energy source field as scheduled.Increase research and development efforts in key technological equipmentThe plan points out that efforts should be made to increase the research and development of key technological equipment and promote diversified technological development.

Carry out research on key core technologies, equipment, and integrated optimization design of new lithium-ion batteries, concentrate on tackling energy storage technologies such as superconductivity and supercapacitors, and develop new generation high energy density energy storage technologies such as liquid metal batteries, solid-state lithium-ion batteries, and metal air batteries. Breaking through the whole process safety technology, breaking through the essential safety control of batteries, safety warning of electrochemical energy storage systems, multi-level protection structures and key materials of the system, efficient fire extinguishing and prevention, and overall safety design of energy storage power stations, supporting the safe operation of large-scale energy storage power stations. Breakthrough in the rapid detection and aging status evaluation technology of energy storage battery cycle life, research and development of retired battery health assessment, sorting, repair and other cascading utilization related technologies, and research on control protection and safety defense technologies for diversified new energy storage integration into the power grid system.Developing new types of energy storage on the grid side according to local conditionsImprove the level of safe and stable operation of the power grid.

Reasonably layout new energy storage in key power grid nodes with intensive load access, large-scale new energy gathering, large capacity DC feeding, difficulties in peak shaving and frequency regulation, and insufficient voltage support capacity, fully leveraging its various functions such as peak shaving, frequency regulation, voltage regulation, accident backup, climbing, and black start, as an important measure to enhance the system's ability to resist emergencies and recover from faults.Enhance the power supply guarantee capability in weak areas of the power grid.

In remote areas with insufficient power supply capacity, such as the power grid terminals in Xinjiang, Inner Mongolia, Xizang and other regions, new energy storage on the grid side should be rationally arranged to improve the power supply guarantee capability.Delay and replace investment in transmission and transformation facilities. In areas where transmission corridor resources and substation site resources are scarce, such as load centers, areas with temporary load increases, and areas with increased demand for phased power supply reliability, support the construction of new energy storage on the grid side, delay or replace the upgrading and renovation of transmission and transformation facilities, and reduce the comprehensive construction cost of grid infrastructure.Improve the system's emergency support capability. Around important power users such as government, hospitals, and data centers, a batch of mobile or fixed new energy storage systems will be built as emergency backup power sources under the premise of safety and reliability, to enhance the system's emergency power supply guarantee capability.Developing new types of energy storage on the user sideThe document proposes to support the construction of distributed energy supply systems. By focusing on end users such as big data centers, 5G base stations, industrial parks, and highway service areas, as well as eligible rural users, new energy storage will be configured based on distributed new energy, microgrids, and incremental distribution networks to improve energy quality and reduce energy costs.Provide customized energy services.

For power users in industries such as communication, finance, and the internet who consume a large amount of electricity and have high requirements for power supply reliability and quality, new energy storage should be configured according to the optimization of business and system operation modes to support high-quality electricity consumption and improve comprehensive energy efficiency and benefits.Enhance the user's ability to adjust flexibly. Actively promote the construction of user side decentralized energy storage facilities such as uninterruptible power supplies and charging and swapping facilities, explore and promote the application of bidirectional interactive intelligent charging and discharging technologies such as smart electricity facilities, and enhance the flexible adjustment ability and intelligent and efficient electricity consumption level of users.
