[I see carbon and peak carbon neutral]

Coal is my country's basic energy and important industrial raw materials. It is in the main position in a energy structure, but it has also become a "big household" for carbon dioxide emissions.

At present, in the context of deeply promoting carbon -to -peak carbon neutralization, how to adhere to establishing first and then breaking, passing through, and promoting the energy revolution. At the same time, consolidate the foundation of domestic energy production and ensure the safety of coal supply? In this regard, the reporter interviewed Xie Kechang, the chairman of the Guanghua Engineering Science and Technology Reward Foundation and the academician of the Chinese Academy of Engineering.

Coal is revolutionary, but it is by no means "the life" of "revolution" coal

"In the past, the energy revolution was once considered to be 'the" life' of coal '. This view is incorrect. "Xie Kechang believes that coal must be revolutionized, but" it is by no means the "life of the" leather' coal '. The industrial chain realizes green development, clean and efficient utilization. The coal that is cleaned and efficient is clean energy. "

For a long time, the resource endowment of "coal rich, poor oil, and less gas" has caused my country to focus on coal -based energy consumption structures. Data show that among the proven reserves of fossil energy resources across the country, coal accounts for about 94%, which is the strongest energy source to stabilize the economy and independent guarantee capabilities. Although the proportion of coal in the first energy consumption is gradually decreasing, it has fallen to 56%in 2021, as a cockpit stone and stabilizer for energy supply in my country, the main energy status of coal in the main body of coal will not change for a long time.

"Coal cleaning and efficient conversion is an inevitable choice for the dual attribute advantages of resources and raw materials and alleviating the tension of oil and gas." Xie Kechang said that at present, it is affected by factors such as the global new crown pneumonia, energy and food crisis. Energy guarantee tasks arduous. "The Party Central Committee and the State Council clearly stated that large enterprises, especially state -owned enterprises, must take the lead in providing stable prices. These are undoubtedly telling us that the rice bowl of energy must be brought in their own hands, and coal is undoubtedly a firm energy rice bowl to achieve my country's energy sources. Safety and controlling the first choice. "

In Xie Kechang's view, although the coal industry is considered a traditional industry, it should be realized that "traditional" only represents the earliest period of emergence, and it does not mean that the sunset industry should not appear in financial support, scientific research support, production capacity The phenomenon of "one -size -fits -all" and "removal of coalization" in various aspects.

He said that the coal industry must strengthen scientific and technological innovation under the premise of ensuring safety production and stable energy supply, and vigorously promote the intelligent mining and efficient utilization technology of coal mines and coal cleaning. The road of- "We must continue to make this large article in the new period of coal cleaning and efficiently, focusing on advanced and efficient coal -fired power generation, coal cleaning and efficient conversion (coal -based new materials, coal -based special oil products), carbon dioxide emission reduction and utilization In the fields of comprehensive utilization of coal resources to carry out coordinated research, this will definitely make traditional industries a new machine and become a strategic emerging industry. "

Working on coal -fired power generation and modern coal chemical industry

In Xie Kechang's view, the current use of coal use in my country is gradually developing to cleaning, large -scale, large -scale, and intensive development. Coal is changing from a single fuel attribute to the direction of fuel and raw materials. Energy low -carbon use. "In the future, the focus of clean and efficient use of coal cleaning and efficient use is mainly in two aspects: coal -fired power generation and modern coal chemical industry."

He said that coal -fired power generation is still the main power supply in my country for a long time. In addition to continuing to ensure the main responsibility of the power supply, coal power also provides flexible peak adjustment services for the large proportion of renewable energy.

"Modern coal chemical industry is an important way to ensure national energy security, especially oil and gas safety. It is recommended that the country steadily promotes the development of modern coal chemical industry represented by coal -made oil and coal -to -olefin, strengthen technological innovation, and gradually promote high -end and high coal chemical products. Value, extend the industrial chain, enhance the value chain, and continue to promote the nearly zero discharge of wastewater, solid waste reduction, and resource use. "Xie Kechang believes that the construction of modern coal chemical projects can only be In order to be fully reflected. It is necessary to actively promote the large -scale, park and base development of the coal chemical industry, and combine the resource endowment to steadily and orderly promote the construction of large modern coal chemical bases.

According to him, my country has now built the world's largest clean and efficient coal power supply system. The super low emissions standards of air pollutants in coal -fired generators are higher than that of major developed countries and regions in the world. Coal -fired power generation is no longer in my country. The main source. At the end of 2021, there were 160 millions of kilowatt super supercritical coal -fired power generation units in my country, which was running, exceeding the sum of other countries. The average power supply consumption of about 280 grams/kWh, leading the development direction of the world's coal -fired power generation technology.

At the same time, my country's coal cleaning and efficient conversion and utilization technology has also obtained a series of innovation breakthroughs: complete sets of key technologies such as direct liquefaction and indirect liquefaction of coal with independent intellectual property rights; independent development of multiple high -efficiency and low -cost gasification technologies with independent intellectual property rights, get rid of it from getting rid of it. Large -scale gasification technology depends on foreign imports; R & D and construction of the world's first million -ton coal -level coal direct liquefied commercial device, and achieve long -term stable operation; develop 4 million tons/year coal indirect liquefaction technology and realize commercial operation; The world's first set of 600,000 tons/annual coal -to -olefin industrialized production device was completed, and the scale of the scale from coal chemicals to petrochemical raw materials was achieved for the first time; major breakthroughs in the development and industrial application of coal -to -acetosol and natural gas such as coal -made natural gas Essence Vigorously support scientific and technological innovation in the energy field

Many people have such a concern: Although my country's coal reserves are high, will there be a day of use?

"As a very valuable non -renewable mineral resources, coal is based on the survey data of the Ministry of Natural Resources in 2021. It confirms that the sum of the reserves and trusted reserves is about 162.2 billion tons. According to the current storage and mining ratio The improvement of efficiency and the direction of utilization from a single fuel to fuel and raw materials are transformed. In addition, the continuous advancement of coal geological exploration will not only be only 40 years. "Xie Kechang said.

At present, carbon -peak carbon and carbon neutrality advances. Xie Kechang said that we must do a good job of technology reserves and strongly support scientific and technological innovation in the energy field: First, implement scientific and technological innovation 2030- "coal clean and efficient use" major projects, break through the bottleneck technology of coal clean and efficient use; Battery power generation, supercritical carbon dioxide power generation and other cutting -edge technologies, strengthen the research and development of coal -based special oil products, coal -based degradable plastic, coal -based high -end carbon materials, explore low energy consumption, low -cost carbon dioxide capture, utilization and geological sealing technology; Large -scale and high -proportion of renewable energy development and utilization, enhance the coupling utilization of fossil energy and renewable energy; fourth is to strengthen cutting -edge technology such as energy storage and hydrogen energy, moderately deploy a batch of hydrogen energy projects, and focus on overcome recycled energy hydrogen production of hydrogen production. The core technologies of hydrogen energy injection, storage and transportation, application, and fuel cells orderly promote the development and demonstration application of hydrogen energy technology.

"Energy revolution and carbon peak carbon neutrality cannot be achieved overnight. In my opinion, their ultimate goal is to cast a modern energy system, build a energy power, so that my country's future energy will fully realize 'reasonable demand, green development, supply, supply Diversity, intelligent allocation, and efficient use. '"Xie Kechang said that, as a responsible country with coal as the main energy source, we must focus on the basic national conditions and development stage, carefully study the international situation, and effectively guarantee energy security supply. Under the premise, combined with the target tasks of carbon peak carbon neutrality, the energy transformation is safely carried out, and the truth is seeking, step by step, and continuous efforts.
