Review of energy storage industry in 2022 and prospect in 2023: the independent status of energy storage is established and the pace of marketization is expected

In 2022, the energy storage industry continued to make new development and innovation. Under the impact of the epidemic, the energy storage industry was no exception. However, the energy crisis and the energy revolution at another level have accelerated the wave of energy storage development. The continuous increase of national policies has given the independent market status of energy storage, which has accelerated the evolution of energy storage from the new energy industry and gradually formed its own independent track and market segment, Therefore, the concept of energy storage has received unprecedented attention in the capital market this year, from household storage to mass storage, from pumped storage to gravity storage, from lithium extraction in salt lakes to sodium ion batteries, from all-vanadium liquid-flow batteries to compressed air storage, from molten salt storage to virtual power plants, etc., fully reflecting people's good expectations for energy storage in different application scenarios.

Throughout the year, the national policy took the lead, especially the introduction of the heavyweight policy - on March 21, 2022, the National Development and Reform Commission and the Energy Administration jointly issued the Implementation Plan for the Development of New Energy Storage during the "Fourteenth Five-Year Plan" - which defined the development goal of new energy storage: by 2025, the new energy storage will move from the initial stage of commercialization to the stage of large-scale development, with the conditions for large-scale commercial application. Among them, the performance of electrochemical energy storage technology was further improved, and the system cost was reduced by more than 30%. On June 1, the National Development and Reform Commission, the National Energy Administration and other nine departments jointly issued the "Fourteenth Five-Year Plan" for the Development of Renewable Energy, clarifying the main position of the independent market for new energy storage, and improving the trading mechanism and technical standards for energy storage to participate in various electricity markets. In addition, the Notice on Further Promoting the Participation of New Energy Storage in the Power Market and Dispatching Application issued on June 7 further clarified the positioning of the new energy storage market, which can be used as independent energy storage to participate in the power market and dispatching application, and established a policy basis for energy storage to open the door to market transactions. The policies in other areas are more diversified and give more powerful development space for energy storage, both on the supply side and on the demand side; Both market mechanism and subsidy support; It covers not only the power generation side, but also the power grid side and the user side. In general, the energy storage industry policy in 2022 can be summarized into three major features: first, the formal implementation of the programmatic policy documents, boosting the determination of industry development; Second, the "one body and two wings" policy tends to be improved to clarify the industry development objectives and the technical and economic benefits of energy storage projects; Third, the supporting policies are issued frequently and widely, and the escort industry can develop sustainably. "One" refers to the "Fourteenth Five-Year Plan" for Renewable Energy Development issued by the National Development and Reform Commission, the Energy Administration and other nine ministries and commissions on June 1, 2022, and the Fourteenth Five-Year Plan for Energy Development issued by provinces and cities; "Two wings" refer to the detailed rules related to auxiliary services issued by each province and the peak electricity price policies issued by each province. The "one body" defines the development objectives, and the "two wings" specify the application scenarios of energy storage in each province to support the implementation of the objectives.

It is the continuous development of the policy that gives a good market atmosphere. In 2022, the total number of energy storage projects to be put on record, bidding, under construction and put into operation and connected to the grid will exceed 1100. According to the preliminary statistics of the Energy Storage Application Branch of the China Chemical and Physical Power Industry Association (revised), a total of 259 energy storage projects will be put into operation from January to December 2022, with a total installed power of 20.7454GW; Among them, there are 236 electrochemical energy storage projects with installed power of 5.663GW/12.2876GWh; A total of 10 non-electrochemical new energy storage projects have been put into operation (6 flywheel energy storage projects, 3 compressed air projects and 1 supercapacitor project), with the operation scale of 0.2774GW/1.1265GWh; A total of 13 pumped storage projects have been put into operation, with an installed capacity of 14.805GW. The total amount of new energy storage is 5.9404GW/13.4141GWh.

From the perspective of technical route, the proportion of pumped storage energy tends to decline, and the subsequent large-scale construction investment in the "14th Five-Year Plan" and "15th Five-Year Plan" will also maintain a high level. The proportion of new energy storage in the overall energy storage market will exceed 13%, and the proportion of lithium iron phosphate battery energy storage in the new energy storage will reach 91%. Compressed air energy storage, flywheel energy storage, supercapacitor energy storage, all-vanadium liquid-flow battery energy storage and sodium-ion battery energy storage are new energy storage technologies with high market popularity and good development prospects, and are expected to make greater progress.

From the perspective of typical energy storage projects actually put into grid in 2022, lithium iron phosphate battery is still the most widely used battery type, and lead carbon battery energy storage, liquid flow battery energy storage, compressed air energy storage, flywheel energy storage and other demonstration projects have been put into grid in succession; The energy storage equipment based on DC side 1500V and liquid cooling and thermal management has gradually become one of the mainstream application technologies at the power generation side and the power grid side. In addition, the topology structures such as string type and high-voltage cascade type will be gradually promoted and applied in the project.

In short, technology is the core driving force to promote the development of the energy storage industry, and the ultimate means to solve the difficult and painful problems faced by the energy storage industry, such as cost, life and safety. Only the continuous iterative updating of technology can better promote the commercialization and large-scale development of the energy storage industry. Observing the development trend of energy storage enterprises in 2022, the industry leaders have launched a number of new energy storage technologies, such as the adoption of new technologies such as large-capacity and long-life battery cells, new topology, liquid cooling and heat management, intelligent inspection system, and network-based energy storage, as well as the strengthening of fire safety configuration, the implementation of closed-loop retirement and waste battery recycling, etc, These measures and progress will help reduce the initial investment cost and life-cycle cost of energy storage, improve the reliability and intrinsic safety level of energy storage, and achieve friendly interaction and efficient support with the grid.

It can be said that 2022 is an important milestone in the development of the energy storage industry. The top planning and design direction is clear and the task is clear. The new type of independent energy storage track is about to take off, and the investment and construction of pumped storage energy will increase in scale and speed up. Of course, the development of any industry cannot be separated from the policy drive, standard construction, market mechanism, business model and iterative upgrading of technology. It is expected that in 2023, it will continue to accelerate the promotion from safety supervision, demonstration application, auxiliary power services, spot power market, demand-side response, virtual power plant, price mechanism and implementation rules, and the energy storage market will present more new hot spots, new business forms and new models. Diversified capital forces and cross-border enterprises entering the energy storage field are accelerating the layout, and the application of new energy storage technologies will be better verified, The industry as a whole is expected to maintain a virtuous cycle of rapid development.
