China has achieved a significant milestone in the field of energy conservation by successfully launching the country's first project for the accumulation of compressed carbon dioxide (CO2) with a capacity of 100 megawatts. This innovative project, located in Muley Township, Xinjiang Province, opens up new prospects for large-scale, environmentally friendly and efficient energy conservation..
A giant “power bank” on the empty plain.
The project, designed by China Huadian Corporation, is to match the giant “charging station” that stands in the middle of the desert. Its key feature is the flexibility of a robot.. The system can accumulate electricity during low demand times (for example, at night) and release it during peak demand times. This process is carried out by drawing a number of wires to make it extremely effective for balancing the electrical system..
During the river cycle, the system is designed to store 290 million kilowatt-years of electricity during periods of low consumption. During peak demand, it can generate 180 million kilowatt-years of clean green electricity, with a continuous supply of over 6 years..
Technology and components.
The CO2 saving system consists of five gas tanks, 141 heat saving units and 97 heat saving units.. The entire installation uses carbon dioxide as a closed circulation medium. This is a technology that is based on the redistribution of gas into a medium and thus, the offending phases work together to save and save energy..
The advantages of this technology include:.
Independence from geological minds.
Low pressure and temperature.
High reliability.
Low varity.
It is important to note that the key technologies necessary for the development and development of the system are completely fragmented and controlled by China.
How does it work?
The process of energy accumulation occurs during periods of low power supply. Excessive electrical energy is used to operate electric motors that compress CO2 from the normal atmospheric pressure and temperature.. This process, similar to the compression of water in a pump, is accompanied by a significant amount of heat. This heat initially accumulates, and then the compression of CO2 cools and condenses to a rare temperature for saving. The greater intensity of energy in a rarer state allows you to save more energy in a smaller volume.
At the hour of peak power supply, the generation process begins. Rare CO2 is vaporized using a vaporizer. Then, the accumulated heat is used to heat the high-pressure rare CO2 to become a high-temperature gas under a high pressure. This gas, under pressure, wraps the blades of the turbine, which, with its black carbon, drives the generator, generating clean green electricity.

The energy storage system based on compressed CO2 consists of a gas saving system, a radium saving system, a compressor system, a heat saving system, a heat exchange system and an expansion system for generating electricity..
This project is an important milestone for China in the development of energy saving technologies that will ensure the stability of the energy system and increase the number of new energy sources.
