Asia’s largest thermal power carbon dioxide capture and storage project was put into operation today.

　　Today (2nd), Asia’s largest thermal power carbon dioxide capture and storage project — — Jiangsu Taizhou Power Plant Project of National Energy Group has been put into operation after several days of full load operation, and it can capture and consume 500,000 tons of carbon dioxide every year.

　　Taizhou Power Plant has four generating units with a power of one million kilowatts. The CO2 capture, utilization and storage project takes the flue gas of Unit 4 as raw material to capture, utilize and store CO2. The project independently developed a new generation of absorbent with high capacity, low energy consumption and long service life. At the same time, it innovatively applied the largest carbon dioxide compressor in China and innovatively integrated technologies such as new packing and high-efficiency amine recovery, which reduced the compression power consumption by 10% compared with traditional projects.

　　Gong Haiting, Director of Special Office of Carbon Resources Development of Jiangsu Taizhou Power Plant of National Energy Group:The project is completely designed, manufactured and installed by China. It is the CCUS project with the highest technical content in the thermal power industry in Asia at present. The carbon dioxide capture rate is over 90%, and the purity of dry carbon dioxide produced is over 99%. All indicators are at the leading level in the industry.

　　The power plant cooperates with relevant enterprises, universities and scientific research institutes to tackle key problems to realize the "deep-level, high-efficiency and large-cycle" use of carbon dioxide, and to run through the full-cycle chain of carbon dioxide from capture to consumption. Users such as oil displacement, welding manufacturing, food-grade dry ice and high-tech machinery cleaning developed by the project will realize 100% absorption and utilization of captured carbon dioxide. The data show that at present, China’s annual carbon dioxide emissions exceed 13 billion tons, of which coal-fired power accounts for over 40%, and coal-fired power is one of the main sources of carbon emissions in China.

　　China’s carbon resource utilization has a new scene.

　　Reducing carbon dioxide emissions is currently considered to be a safe and effective way to solve the global greenhouse effect. The coal industry is the main battlefield of carbon emission reduction, and how to solve the carbon emission problem of coal-fired power generation is very important to reduce the total carbon emission.

　　In recent years, various industries have made some explorations in reducing the total amount of carbon dioxide emissions. Most enterprises collect carbon dioxide and seal it, while Taizhou Power Plant’s carbon dioxide capture and storage project treats the flue gas after coal combustion, purifying the captured carbon dioxide to more than 99%, and then using it in industrial scenes and food processing scenes.

　　Gong Haiting, Director of Special Office of Carbon Resources Development of Jiangsu Taizhou Power Plant of National Energy Group:The failure to fully consume carbon dioxide has always been a blocking point that restricts the sustainable operation of CCUS project. Taizhou Power Plant has realized the full consumption of 500,000 tons/year by investigating the surrounding parks and enterprises, docking the demand for carbon dioxide use, and effectively connecting the regional carbon cycle, and has stable profitability, which provides a sample for the long-term sustainable operation of coal-fired CCUS.

　　In recent years, China has accelerated the construction of carbon capture, utilization and storage projects. The carbon capture, utilization and storage project can capture and separate carbon dioxide from industrial, energy production and other emission sources or air, and use it or transport it to a suitable site for storage, and finally realize carbon dioxide emission reduction. By the end of 2022, China has put into use 13 coal-fired power carbon dioxide capture, utilization and storage projects, with a total capture capacity of about 600,000 tons per year.

　　Where did the captured carbon dioxide go?

　　Where did a lot of carbon dioxide go after capture? In recent years, the technology of carbon capture, utilization and storage in China has developed rapidly, and all walks of life have carried out some exploration and practice.

　　Just yesterday, China CNOOC started China’s first 10-million-ton carbon dioxide capture, utilization and storage cluster project in Huizhou, Guangdong Province, which captured the carbon dioxide emitted by petrochemical enterprises in Daya Bay and transported it to the sea for storage, exploring a new way for China to achieve the goal of carbon neutrality in peak carbon dioxide emissions.

　　Deng Changhong, Deputy General Manager of China CNOOC Shenzhen Branch:China CNOOC will carry out research and demonstration application of integrated technology of geological reservoir, drilling and completion and engineering for offshore oil and gas fields with high carbon dioxide content, form China’s independent technology system and equipment, build a safe and controllable carbon dioxide capture and storage technology system, realize scale emission reduction, and promote the green and low-carbon transformation of offshore oil and gas industry.

　　In Taizhou, Jiangsu, Asia’s largest thermal power carbon dioxide capture and storage project — — Taizhou Power Plant of Jiangsu, a national energy group, can capture and purify 500,000 tons of carbon dioxide every year, and many innovative technologies provide a new path for China to reduce emissions. The project has successfully developed users such as oil displacement, welding manufacturing, food-grade dry ice and high-tech machinery cleaning, and will realize 100% consumption and utilization of captured carbon dioxide.

　　Liu Jiandong, Chief Engineer of Jiangsu Taizhou Power Plant of National Energy Group:On our side, shipyards, oil fields, chemical plants and other enterprises have a great demand for carbon dioxide. In the early stage, we took the initiative to dock enterprises in the park and locked in an annual sales volume of 500,000 tons, including 400,000 tons of carbon dioxide for industrial use and 100,000 tons of carbon dioxide for food processing.

　　The annual report of carbon dioxide capture, utilization and storage (CCUS) in China (2021) shows that there are about 40 CCUS demonstration projects that have been put into operation or under construction in China, with a carbon capture capacity of about 3 million tons/year and an annual injection of about 1.8 million tons. The industries involved in capture sources and the types of storage and utilization are diversified.
