 Academician: We must vigorously promote clean, efficient and sustainable development and utilization of coal


Strive to basically solve the problem of water, wind and light abandonment by 2020, and ultimately achieve that non-fossil energy accounts for 15% and 20% of primary energy consumption by 2020 and 2030. Clean energy will be the overall goal of the main energy sources by 2050.

Zhang Jianhua, Director-General of the State Energy Administration, recently held the 2019 High-end Forum on Clean Power International Engineering Science and Technology and the International High-end Forum on Clean Energy of the National Energy Group. He said that he would further strengthen the top-level design of clean energy substitution, promote the clean and efficient use of fossil energy, and promote the development of the energy system towards a clean and low-carbon direction.

Xie Kechang, academician of the Chinese Academy of Engineering and expert of coal chemical industry attending the forum at the same time, said that clean and efficient use of coal is also clean energy. The progress of technology has further improved the harmless utilization of coal, and the level of clean utilization of coal in China will reach a new level.

Clean and efficient use of coal is also clean energy

Xie Kechang said that Chinas energy structure and the relationship between supply and demand determine that China must vigorously promote the clean, efficient and sustainable development and utilization of coal as a foothold and primary task of energy transformation and development.

Through ultra-low emission technology and end treatment, the particulate matter in coal power generation process can be reduced to the lowest level, and the particulate matter emission enlargement after ultra-low emission can be reduced greatly. Another way of clean coal utilization is to produce clean fuel. In the process of thermal conversion, coal can highlight harmful components, and harmful substances in coal can reach negative poles and be treated harmlessly. Xie Kechang said.

Xie Kechang introduced that the Chinese Academy of Engineering started the research project of clean, efficient and sustainable development and utilization of coal in China in 2011. Dozens of academicians and hundreds of experts studied the project for two and a half years. Through a large number of investigation and analysis and model analysis, from the seven aspects of science and technology driving, green development, comprehensive quality upgrading, transportation optimization, advanced power generation transformation and upgrading, energy saving and consumption reduction, they are in the whole industrial chain. To achieve clean and efficient.

The worlds largest clean and efficient coal-fired power system has been built

As the largest energy producer and consumer in the world, China has achieved many positive results in energy transformation and development. Since the reform and opening-up 40 years ago, Chinas energy supply capacity has been greatly improved, the structure of energy supply has been continuously optimized, and energy consumption has been continuously low-carbon and clean. Chinas clean power development scale in the field of electricity has led the world.

Data show that by the end of 2018, Chinas renewable energy power generation has broken through 700 million kilowatts. Among them, hydropower, wind power and photovoltaic power generation have reached 350 million, 180 million and 170 million kilowatts, ranking the first in the world, nuclear power generation has reached 4464 kilowatts, rebuilding 12.18 million kilowatts and rebuilding the first in the world. Overall, Chinas non-fossil energy power generation accounted for about 40% of the total power generation. At the same time, China has built the largest clean and efficient coal-fired power system in the world, with over 800 million kilowatts of ultra-low-emission coal-fired power units, leading the world in emission standards.

Zhang Jianhua said that he would accelerate the research and development of key core technologies in the fields of clean and efficient utilization of coal, smart grid, new nuclear power, ignition units, hydrogen energy and fuel cells, deep-sea and unconventional oil and gas, and promote the integration of technologies such as Internet, Internet of Things, big data, cloud computing and artificial intelligence with the energy industry.

For future clean energy transformation tasks, major energy enterprises have taken early action.

Wang Xiangxi, chairman of the State Energy Group, said that the State Energy Group had built the first high-efficiency coal-fired generating unit in China to achieve ultra-low emissions, and realized that more than 90% of the pollutant emissions of the groups coal-fired units were lower than the national emission standards of gas-fired units. The Taizhou Power Plant with the highest comprehensive power generation efficiency of secondary reheat and ultra-supercritical coal-fired was built. The core technologies of direct liquefaction of millions of tons of coal, indirect liquefaction of 4 million tons of coal per year and production of olefins from 600,000 tons per year of coal have been conquered and a demonstration project has been established, which further consolidates the cornerstone of energy security in China. Actively explore carbon dioxide capture and storage (CCS) technology, and build the worlds first 100,000 tons per year coal chemical industry process CCS demonstration project.

In addition, the National Energy Group is the worlds largest wind power company with 38 million kilowatts of wind power installed. Actively explore new energy technologies, carry out technical research on copper, indium, gallium and selenium solar thin film cells, and form a five in one industrial chain; take the lead in setting up the China Hydrogen Energy and Fuel Cell Industry Innovation Strategic Alliance to explore the development path of hydrogen energy industrialization in China.

Continue Deepening Marketization Reform and Promoting Clean Energy Development

Zhang Jianhua also stressed that we should deepen the reform of energy marketization, restore the commodity attributes of energy, focus on solving outstanding problems in the reform, further improve the market-oriented trading mechanism of electricity, and promote the reform of the management system of oil and gas exploration and development and the operation mechanism of oil and gas pipelines.

Huang Qili, academician of the Chinese Academy of Engineering, said in an interview with the First Financial and Economic Journalist that the long-term plan is to establish the electricity market as soon as possible and break the serious barriers between provinces through policies. He said that the establishment of the electricity market can enable the people to automatically follow the changes in the electricity market, and the barriers between provinces can also promote the effective use of local and surrounding areas of clean energy by examining the electricity structure.

While promoting the increase of the proportion of clean energy, we should also speed up the reduction of the cost of renewable energy and enhance the economy of renewable energy through market-oriented regulation.

For example, Ni Weidou, academician of the Chinese Academy of Engineering, told First Finance and Economics that some power plants burn biomass to completely replace coal. This carbon reduction measure is inappropriate for the business model, and it is easier to control the recovery price of biomass by blending combustion. He believed that the blending of coal and biomass should be gradually promoted in China, and the proportion of biomass blending should be gradually increased. At the same time, a real biomass industry should be gradually formed. It should be combined with the problems of agriculture, countryside and farmers, and suitable waste land should be used to grow energy plants to solve the problems of biomass supply and collection.
