We must promote clean, efficient and sustainable development 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, said that the top-level design of clean energy substitution would be further strengthened, fossil energy clean and efficient utilization would be promoted, and energy system would be developed towards a clean and low-carbon direction. Xie Kechang, academician of the Chinese Academy of Engineering and expert of coal chemical industry, who attended 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 coal is also clean energy

Xie Kechang said that China's energy structure and supply-demand relationship 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 minimum, and the emission of particulate matter can be greatly reduced after ultra-low emission. 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 it for two and a half years. Through a large number of investigation and model analysis, from the seven aspects of science and technology driving, green development, comprehensive quality improvement, transportation optimization, transformation and upgrading of advanced power generation, energy saving and consumption reduction, the whole production was carried out. Clean and efficient industry chain.

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

Data show that by the end of 2018, China's renewable energy power generation has broken through 700 million kilowatts, including 350 million, 180 million and 170 million kilowatts of hydropower, wind and photovoltaic power, ranking first in the world, 4464 kilowatts of nuclear power generation, 12.18 million kilowatts of re-construction, and the first in the world. Overall, China's 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 and leading emission standards in the world.

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 unit, hydrogen energy and fuel cell, deep sea and unconventional oil and gas, and promote the integration and development of technologies such as Internet of Things, big data, cloud computing, artificial intelligence and energy industry.

For the future clean energy transformation task, the major energy enterprises have taken early action. Wang Xiangxi, chairman of National Energy Group, said that National 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 coal-fired units in the group were lower than the national emission standards of gas-fired units; and built Taizhou Power Plant with the highest comprehensive generation efficiency of secondary reheat and ultra-supercritical coal-fired power plants in the world. 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 world's first 100,000 tons per year coal chemical industry process CCS demonstration project. In addition, the National Energy Group is the world's 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 to deepen market-oriented reform to promote clean energy development

Zhang Jianhua also stressed that we should deepen the reform of energy market-oriented, 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 oil and gas exploration and development management system and the operation mechanism of oil and gas pipelines. Huang Qili, academician of the Chinese Academy of Engineering, said in an interview with First Financial 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, it is also necessary to speed up the reduction of the cost of renewable energy and the improvement of the economy of renewable energy through market-oriented regulation.
