Compressed air can be used to generate electricity, and after the heat generated during the power generation process is recovered, it can also be used for heating. The reporter learned from the Chongqing Science and Technology Commission that Chongqing Jingtian Energy Investment (Group) Co., Ltd. has recently developed the world's first high-performance "air power storage power generation system" that uses compressed air to generate electricity.

　　Using compressed air to generate electricity

　　 In the laboratory of Chongqing Jingtian Energy Investment Group, the reporter saw that the air power storage energy system is mainly composed of four parts: intelligent control system, air compressor, air storage tank and generator set, and the core part is the air storage system. In layman's terms, its function is to use air to generate electricity, which can generate 15 kWh per hour.

　　The principle of compressed air power generation

　　 This system must first store compressed air and use the original energy to support the operation of the system. This original energy can be solar energy, wind energy, etc., through the internal energy conversion of the equipment to generate electricity. At the same time, the embedded microcomputer intelligent control system tracks the load demand in real time and automatically adjusts the switching load according to the reserve. Moreover, the system has a network communication function, which can realize remote cloud management, and realize the monitoring, control, and remote switching operation of the system through the network, so as to avoid the safety risks caused by operators entering the energy storage high-voltage area.

　　According to the person in charge of the project, this system is used to replace conventional battery energy storage methods for wind power and photovoltaic power generation, which can eliminate the environmental pollution risk of the energy storage system. Liu Qi, chairman of Jingtian Group, told reporters that the entire system is driven by solar and wind energy. Under the "command" of the control system, it first collects and compresses air through an air compressor, and stores it in an air storage tank. When power is generated, the air is released to drive the generator set to generate electricity, and the loss of this system is low, and the overall power generation efficiency can reach more than 65%.

　　 The air compressor also generates heat in the process of compressing air, which can heat the room, and the heat recovery can make the air temperature reach 30°C.

　　In the market, it is estimated to make hundreds of millions

　　According to the relevant person in charge of the Chongqing Science and Technology Commission, at present, similar equipment at home and abroad requires liquid mixed compressed air, and the aerodynamic storage energy system belongs to pure compressed air power generation, filling a gap in the market, and is a domestic and foreign initiative. At present, 15 kilowatts to 5 megawatts of equipment can be provided, which means that 15 kWh-5000 kWh can be generated per hour, and the investment cost per kWh of electricity using this set of equipment is less than 1,000 yuan. The investment cost is about 8,000 yuan, which is equivalent to a 7-fold reduction in the investment cost per kilowatt-hour of electricity. This greatly reduces the cost. When it is put into the market, the annual profit is estimated at 100-200 million.

　　What fields can the system be applied to?

　　 According to the relevant person in charge of Jingtian Energy Investment Group, the current conversion efficiency of this equipment can reach 60% after testing, and it is expected to reach 65% after mass production. This equipment can solve the problem of the storage of the bottom of the utility power, which is called abandonment in the power industry. The air storage power generation system can be used to store this part of the power and supplement the power during the peak period of power consumption.

　　 can also solve the problems of wind power and solar power storage. It can be used for electricity consumption in plateau areas and remote mountainous areas to reduce the frequency of abandoning light and wind. In addition, it can also be used to store electricity for border guard posts and China-aided countries in Africa, Latin America, and Central Asia for solar and wind energy, which not only saves about billions of investment in power lines for remote mountain residents, but is also clean and environmentally friendly. The price of this laboratory equipment is about 15,000 yuan.

　　 Focusing on the core technology of the aerodynamic storage energy system, Jingtian Group has applied for 8 national patents, one of which has been authorized.

It is understood that Jingtian Group has signed a 200-kilowatt aerodynamic storage energy system contract in Guizhou, and also signed a multi-energy complementary distributed energy strategic cooperation agreement with Kazakhstan, including the provision of 5 MW aerodynamic storage. The energy system is applied in Kazakhstan.
