Recently, the national development and Reform Commission and the National Energy Administration jointly issued the implementation plan for the development of new energy storage in the 14th five year plan (hereinafter referred to as the plan).
The plan requires that by 2025, the new energy storage will enter the stage of large-scale development from the initial stage of commercialization, and have the conditions for large-scale commercial application. The innovation ability of new energy storage technology has been significantly improved, the independent and controllable level of core technology and equipment has been greatly improved, the standard system has been basically improved, the industrial system is becoming more and more complete, and the market environment and business model are basically mature. Among them, the performance of electrochemical energy storage technology is further improved, and the system cost is reduced by more than 30%; Steam extraction and energy storage of thermal power and nuclear power units rely on the new energy storage technology of conventional power supply and 100MW compressed air energy storage technology to realize engineering application; Megawatt flywheel energy storage and other mechanical energy storage technologies are gradually mature; Breakthroughs have been made in long-time scale energy storage technologies such as hydrogen energy storage and hot (cold) energy storage.
By 2030, new energy storage will be fully market-oriented. The new energy storage core technology and equipment are independent and controllable, the technological innovation and industrial level are firmly in the forefront of the world, the market mechanism, business model and standard system are mature and sound, and are deeply integrated with all links of the power system, which basically meets the needs of building a new power system and comprehensively supports the realization of the goal of carbon peak in the energy field as scheduled.
The plan proposes to strengthen the development of new energy storage on the power side. Promote the construction of system friendly new energy power stations. In areas rich in new energy resources, such as Inner Mongolia, Xinjiang, Gansu and Qinghai, as well as other areas with high penetration of new energy, focus on the layout of a number of system friendly new energy power stations with reasonable new energy storage, promote the application of innovative technologies such as high-precision long-time scale power prediction and intelligent dispatching control, and ensure the efficient consumption and utilization of new energy, Improve the new energy and improve the user friendliness and capacity support capacity.
Support the export of a high proportion of renewable energy bases. Relying on the stock and the new trans provincial and trans regional transmission channels in the 14th five year plan, give full play to the role of large-scale new energy storage in the northeast, North China, northwest and southwest. Through the multi energy complementary mode of "integration of scenery, water and fire storage", promote the trans provincial and trans regional transmission and consumption of large-scale new energy, and improve the utilization rate of channels and the proportion of renewable energy.
Promote the development and consumption of large-scale wind power photovoltaic bases in Gobi desert. Cooperate with the development of large-scale wind power photovoltaic bases in desert, Gobi, desert and other regions, study the configuration technology, reasonable scale and operation mode of new energy storage, explore the use of renewable energy to produce hydrogen and support large-scale new energy export.
Promote large-scale offshore wind power development and consumption. Combined with the development of large-scale offshore wind power bases in Guangdong, Fujian, Jiangsu, Zhejiang, Shandong and other regions, carry out research on new energy storage of offshore wind power configuration, reduce the capacity demand of offshore wind power collection and transmission channel, and improve the consumption and utilization level and capacity support capacity of offshore wind power.
Improve the regulation ability of conventional power supply. Promote the rational allocation of new energy storage for coal and electricity, carry out the demonstration of steam extraction and energy storage, and improve the operation characteristics and overall benefits. Explore and carry out new energy storage combined with nuclear power peak shaving and frequency modulation and multi scenario applications. Explore the use of existing plant sites and power transmission and transformation facilities of decommissioned thermal power units to build new energy storage or wind and solar energy storage facilities.
The plan also proposes to explore and promote the shared energy storage mode. Encourage new energy power stations to allocate energy storage in the form of self construction, lease or purchase, and give play to the sharing role of "one station for multiple purposes" of energy storage. Actively support various entities to carry out the application demonstration of innovative business models such as shared energy storage and cloud energy storage, and pilot the construction of shared energy storage trading platform and operation monitoring system.
The plan specifies to carry out research on key core technologies, equipment and integrated optimization design of sodium ion battery, new lithium ion battery, lead carbon battery, liquid flow battery, compressed air, hydrogen (ammonia) energy storage, hot (cold) energy storage and so on. Expand the application fields of hydrogen (ammonia) energy storage and hot (cold) energy storage, and carry out pilot demonstration of hydrogen (ammonia) energy storage based on hydrogen (ammonia) production from renewable energy and energy storage in waste mines. Aiming at the problems of new energy consumption and system peak shaving, promote the demonstration of energy storage technology with large capacity and medium and long-term scale. Focus on pilot demonstration of compressed air, liquid flow battery, high-efficiency heat storage and other day to week and week to quarter time scale energy storage technologies, as well as longer cycle energy storage technologies such as hydrogen production and ammonia production from renewable energy, so as to meet the needs of multi time scale applications.
In terms of hydrogen energy, the plan points out that by 2025, new energy storage will enter the stage of large-scale development from the initial stage of commercialization and have the conditions for large-scale commercial application. Breakthroughs have been made in long-time scale energy storage technologies such as hydrogen energy storage and hot (cold) energy storage. We will strengthen the research and development of key technical equipment, promote the development of diversified technologies, and carry out a new generation of high energy density energy storage technologies such as hydrogen (ammonia) energy storage.
