New Energy Storage Enters A Period Of Large-scale Development

This year's "Government Work Report" proposes to strengthen the construction of large-scale wind power and photovoltaic bases and transmission channels, promote the development and utilization of distributed energy, improve the power grid's ability to accept, allocate and regulate clean energy, develop new energy storage, promote the use of green electricity and international mutual recognition, give full play to the bottom line role of coal and coal-fired power, and ensure the energy demand for economic and social development. This is the first time that my country has written "development of new energy storage" into the government work report. In recent years, with the continued rapid growth of my country's new energy power generation scale, new energy storage has entered a period of large-scale development. Since the "14th Five-Year Plan", the addition of new energy storage installed capacity has directly promoted economic investment of more than 100 billion yuan, strongly supported the development of energy and electricity, and became a new driving force for China's economic development. Our product, new energy Aluminum Battery Case, can be well used in the energy storage industry and has a driving role in the good development of new energy storage.

 

 

In October 2022, the all-vanadium liquid flow battery energy storage technology independently developed by the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, blossomed in Dalian City, Liaoning Province. The first phase of the Dalian all-vanadium liquid flow battery energy storage peak-shaving power station built based on this technology was officially connected to the grid for power generation. "At present, the first phase of the power station can store up to 400,000 kWh of electricity. Based on the daily per capita electricity consumption of 2 kWh in my country, it can meet the daily electricity demand of 200,000 residents." According to Li Xianfeng, deputy director of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, after the power station is fully built, it can store 800,000 kWh of electricity at a time. The Dalian all-vanadium liquid flow battery energy storage peak-shaving power station is a microcosm of my country's active development of new energy storage technology application scenarios, promotion of the development of new energy storage industries, and acceleration of the construction of new energy systems. Energy storage plays an important role in accelerating the construction of new energy systems. Chen Haisheng, director of the Institute of Engineering Thermophysics of the Chinese Academy of Sciences and chairman of the Energy Storage Committee of the China Energy Research Society, said: "Energy storage is a process of storing energy in a certain form and releasing it when needed. Its most important role is to solve the mismatch between energy production and demand in time, space and intensity." Aluminum Alloy Battery Case is made of high-quality aluminum materials, which can provide good stability and corrosion resistance in new energy electric vehicles and photovoltaic energy storage.

 

In recent years, with the rapid development of new energy such as wind energy and solar energy, the impact of its intermittent and volatile nature on the security of the power grid has become increasingly prominent. "It is necessary to build an energy storage system to ensure the security of energy and the stable operation of the energy system." Chen Haisheng said that energy storage is like a "power bank", which can store the surplus electricity of new energy such as wind power and photovoltaics, and discharge it during peak electricity consumption. "This can not only promote the development and consumption of large-scale new energy such as wind power and photovoltaics, but also provide auxiliary services such as peak load regulation and frequency regulation for the operation of the power system, and improve the flexibility of the power system." He said. Energy storage is divided into traditional energy storage and new energy storage. Traditional energy storage mainly includes pumped storage, and new energy storage includes lithium-ion batteries, flow batteries, compressed air energy storage, flywheel energy storage, etc. Chen Haisheng told reporters that compared with traditional energy storage, new energy storage has the characteristics of short construction period, flexible site selection, strong regulation ability and fast response. The interviewed experts said that as my country accelerates the construction of a new power system with new energy as the main body, new energy storage technologies are diversified and accelerated, and application scenarios are constantly expanding. New energy storage has shifted from pilot demonstration to large-scale commercial use, ushering in a golden period of rapid development. According to data from the National Energy Administration, by the end of 2023, the total installed capacity of new energy storage projects that have been built and put into operation nationwide has reached 31.39 million kilowatts/66.87 million kilowatt-hours, with an average energy storage time of 2.1 hours. The newly installed capacity in 2023 will be about 22.6 million kilowatts/48.7 million kilowatt-hours, an increase of more than 260% from the end of 2022. Aluminum Battery Box can be used in various new energy storage systems, which can maintain the good output and input performance of lithium batteries. Aluminum alloy materials are easy to recycle and meet the requirements of modern industry for environmental protection and sustainable development.

 

 

 

From charging and swapping stations to new energy stations and power grid peak and frequency regulation, the rapid development of new energy storage and the continuous expansion of application scenarios are inseparable from the strong support of new technologies. In Feicheng, Shandong, the world's first 300 MW advanced compressed air energy storage national demonstration project has completed the main construction and is carrying out system integration and commissioning. Relying on the advanced compressed air energy storage technology independently developed by the Institute of Engineering Thermophysics of the Chinese Academy of Sciences, the project is expected to become the world's largest single-unit and best-performing new compressed air energy storage power station after completion. Ji Li, general manager of China Storage National Energy (Beijing) Technology Co., Ltd., incubated by the Institute of Engineering Thermophysics of the Chinese Academy of Sciences, said: "The advanced compressed air energy storage technology we have developed can simultaneously solve the main technical bottlenecks of traditional compressed air energy storage, such as reliance on large gas storage caves, reliance on fossil fuels, and low system efficiency. The R&D team has broken through the core key technologies of 1 to 300 MW compressed air energy storage systems and has completely independent intellectual property rights." In Shenzhen, Guangdong, the Guangdong Energy Group's semi-solid battery energy storage demonstration project is accelerating. The semi-solid battery energy storage equipment used in this project comes from Beijing Weilan New Energy Technology Co., Ltd., a solid-state battery technology industrialization platform of the Institute of Physics, Chinese Academy of Sciences. With the rapid development of new energy storage, the demand for lithium batteries has also increased. The good performance and quality of LiFePO4 Aluminum Case Battery Cell can ensure its good heat dissipation in the energy storage system.

 

 

Led by Academician Chen Liquan, the research and development team of the Institute of Physics, Chinese Academy of Sciences has been studying solid-state batteries since the 1970s. Li Hong, a researcher at the institute, said: "The lithium iron phosphate solid-state energy storage battery developed by our team has a higher safety level and longer cycle life. The current number of cycles can reach 6,000 to 10,000 times." According to experts, my country's current lithium-ion battery, compressed air energy storage and other technologies have reached the international leading level. With the continuous advancement of science and technology, energy storage technology will develop in the direction of diversification, large-scale and high efficiency in the future. Our lithium battery aluminum shell is used in lithium iron phosphate solid-state energy storage batteries and various other energy storage batteries. The large-scale and environmentally friendly production of it effectively promotes the development of new energy storage. Chen Haisheng believes that in the future, long-term large-scale energy storage and grid-type energy storage technologies will receive much attention, and various technologies such as battery energy storage, supercapacitors, and compressed air energy storage will accelerate integration. With the continuous advancement of technology, the construction and operation costs of energy storage systems will gradually decrease, better supporting the construction of new energy systems. "New energy storage technologies will also be deeply integrated with artificial intelligence, big data, cloud computing, etc. to achieve more efficient and intelligent energy storage and utilization." Li Hong said.

 

 

In recent years, my country has introduced a series of relevant policies to promote and encourage the development and construction of energy storage projects. The 14th Five-Year Plan and the Outline of the 2035 Vision Goals propose to accelerate the construction of pumped storage power stations and the large-scale application of new energy storage technologies. In January 2022, the "14th Five-Year Plan for New Energy Storage Development Implementation Plan" jointly issued by the National Development and Reform Commission and the National Energy Administration proposed 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; by 2030, new energy storage will be fully market-oriented. It has become an industry consensus to accelerate the large-scale, industrialized and market-oriented development of new energy storage. Chen Haisheng believes that energy storage installed capacity will continue to grow rapidly in 2024, and it is expected that more than 40 gigawatts of new installed capacity will be added throughout the year. my country's energy storage will achieve a substantial transformation from the initial stage of commercialization to large-scale development. The experts interviewed pointed out that it is necessary to start from improving technical levels, improving market mechanisms, improving safety prevention and control, and reducing application costs to further promote the high-quality development of the energy storage industry. The application of Aluminum Deep Drawing Stamping Battery Case in various new energy storage can provide effective mechanical strength. The aluminum alloy material used has excellent mechanical strength and impact resistance, and can protect the internal components of the battery from external impact and collision.

 

 

At present, except for relatively mature technologies such as lithium-ion batteries, flow batteries, compressed air energy storage, and flywheel energy storage, other new energy storage technology routes are still in the demonstration and verification stage, with low technical maturity and less operational experience in commissioned projects. Experts said that it is necessary to seize the time window, verify the economic feasibility of the technology route through a series of demonstration projects, and focus on the difficulties and pain points of industry development to jointly organize research and accelerate the breakthrough of intelligent core technologies that are safe and reliable, with high system efficiency and convenient operation and maintenance. The energy storage industry is highly price sensitive. At present, my country's new energy storage market has not yet formed a stable revenue model. The low profit level and difficulty in forming a reasonable cost diversion mechanism are the problems that plague the development of new energy storage. Chen Haisheng said that for energy storage to enter the power system, a more reasonable price mechanism and market environment should be established. "The value of energy storage should be measured from a global perspective, and the principle of 'whoever benefits, whoever bears' should be adhered to, to establish a reasonable energy storage price mechanism that is shared by power generation, power grid, and users." Yu Huigen, chairman of Beijing Weilan New Energy Technology Co., Ltd., believes that it is necessary to improve the performance and quality of energy storage products and to establish and improve graded and quantitative national and industry standards as soon as possible. The interviewees said that with the rapid development of technology and the improvement of relevant policies, new energy storage will provide stronger new momentum for accelerating the construction of a new energy system and developing new quality productivity.
