Description
The first 100 MW advanced compressed air energy storage demonstration power station in the world
At 17: 00 on September 30, the first international 100 MW advanced compressed air energy storage national demonstration project was successfully connected to the grid in Zhangjiakou, Hebei Province.
The total scale of the project is 100 MW/400 MW, the core equipment autonomy rate is 100, and the annual power generation is more than 0.132 billion kWh. It can provide power guarantee for about 50000 users at the peak of power consumption, and can save 42000 tons of standard coal per year., Reducing carbon dioxide emissions by 109000 tons, is currently the world's largest single-unit and most efficient new compressed air energy storage power station.
The technology of the demonstration project is provided by the Institute of Engineering Thermophysics, Chinese Academy of Sciences (hereinafter referred to as the Institute of Engineering Thermophysics). The investor is Giant Group Zhangbei Giant Energy Co., Ltd., and the equipment provider is Zhongchu Guoneng (Beijing) Technology Co., Ltd. The project will start construction in October 2020, complete equipment installation and system integration in December 2021, and start live commissioning.
Xu Yujie, a researcher at the Institute of Engineering Thermophysics and director of the Energy Storage R & D Center, told China Science Daily that energy storage technology is the key support technology to achieve the goal of "carbon peak and carbon neutrality". Advanced compressed air energy storage technology has the advantages of large scale, low cost, long life, clean and pollution-free, unlimited energy storage cycle, dependence on fossil fuels and geographical conditions, and is a long-term large-scale energy storage technology with great development potential, it can realize power system peak regulation, frequency modulation, phase modulation, spinning standby, black start, etc., and has broad development space and strong competitiveness in improving power system efficiency, safety and economy.
Reporters learned that traditional compressed air energy storage mainly uses low-grade and low-quality electricity to compress and store air in large gas storage caves. At the peak of electricity consumption, high-pressure air is released from the gas storage cave and burned with fuel to drive the turbine to generate electricity. At present, it has been commercially applied in Germany and the United States. However, there are three main technical bottlenecks in traditional compressed air energy storage. One is to rely on fossil fuels to provide heat source; the other is to rely on natural gas storage caves, such as rock caves, salt caves, abandoned mines, etc.; the third is that the system efficiency is low and needs to be further improved.
In recent years, in response to the bottleneck of traditional compressed air energy storage technology, countries have actively developed new compressed air energy storage technologies, including regenerative compressed air energy storage systems, isothermal compressed air energy storage systems, and liquefied air energy storage systems. The Institute of Engineering Thermophysics began to focus on the research and development of compressed air energy storage technology in 2004, and originally proposed a new principle of advanced compressed air energy storage technology in 2009. Since 2013, from 1.5 MW, 10 MW to 100 MW, basic theories such as system process coupling and dynamic optimization have been developed, key technologies such as multi-stage compressors and expanders, high-efficiency compact heat storage heat exchangers, and system integration and control technologies have been broken through, and engineering demonstrations have been completed.
Xu Yujie introduced that after the completion of Zhangjiakou International's first 100-megawatt advanced compressed air energy storage national demonstration project, a new large-scale energy storage system operation model and strategic emerging industrial clusters can be formed, which will effectively promote the scale and industrialization of my country's compressed air energy storage technology. The development process of commercialization is a milestone in promoting the energy revolution and building a new power system.
The above-mentioned related work has been supported by the Chinese Academy of Sciences Class A pilot project "Key Technologies and Demonstration of Transformative Clean Energy", the National Renewable Energy Demonstration Zone Major Project of the National Development and Reform Commission, and the National Science Fund for Distinguished Young Scholars.
