In order to achieve the goal of carbon peak carbon neutralization, the action plan and roadmap of carbon peak in steel industry have been basically clear《 The reporter of economic reference newspaper learned that the action plan for carbon peak and carbon reduction in steel industry (hereinafter referred to as the plan) has been revised and perfected, and the target and key tasks of the industry to reach peak have been preliminarily determined.

According to relevant sources, under the constraints of 2030 "carbon peak" and "carbon neutralization" in 2060, the carbon peak target of steel industry is initially set as: to achieve the peak carbon emission by 2025; By 2030, carbon emissions will be reduced by 30% compared with the peak, and it is expected to achieve 420million tons of carbon emission reduction.

Specifically, the four nodes of realizing carbon peak and carbon emission reduction in steel industry are: 2025 carbon emission reaches peak; In 2030, the total carbon emissions will decrease steadily; In 2035, there was a significant decline; China's steel industry will be decarbonized in depth by 2060 years ago.

Li Xinchuang, Secretary of the Party committee and chief engineer of the metallurgical industry planning and Research Institute, said that the steel industry is a key area to promote the implementation of the comprehensive goal of carbon reaching peak, the key link of local implementation of carbon peak, and the main battlefield for promoting green and low carbon development. As the largest crude steel production and consumption country in the world, China's crude steel production accounts for more than half of the global crude steel production, carbon emissions account for more than 60% of the global total carbon emissions of steel, accounting for about 15% of China's total emissions. The importance of steel emission reduction is self-evident.

Li said the goal of reaching the peak in the steel industry is to use limited carbon emissions well. The goal of carbon neutralization is to realize the decoupling of industry development from carbon dioxide emissions and energy consumption.

"At present, the low-carbon transformation of steel faces a big challenge." According to Li Xinchuang, from the current energy structure of China, the high to long process structure still dominates, with high carbon energy structure and coal and coke accounting for nearly 90% of energy input. The space of economic and feasible carbon reduction is limited, and the marginal cost of energy conservation and carbon reduction is increasing day by day.

In addition, Li said that on the one hand, steel consumption demand is still high, and crude steel production is difficult to reduce; On the other hand, the increase of short-term steel consumption expectation or further drive the industry investment impulse, resulting in a new stage of waste. Investment in ferrous metal smelting and calendering industry increased 27.5% year-on-year in 2020, far higher than the average growth rate of manufacturing investment, he said. All of these may lead to the difficulty of achieving the carbon reduction target.

Therefore, in the short term, reducing steel production or steel industry is the primary issue. Luotiejun, vice president of China Iron and Steel Industry Association, said that the steel industry should strive to achieve the peak carbon in advance during the 14th Five Year Plan period, starting with the decrease of steel production, especially the decrease of iron production.

"Strictly adhering to the bottom line of not adding new capacity and strictly controlling the growth of crude steel capacity is the focus of steel supervision this year." The relevant leaders said that this year, relevant ministries will formulate and issue stricter implementation measures for capacity replacement in the steel industry, and further standardize capacity management. Meanwhile, the dual control of production capacity and production capacity is implemented, and the steel production capacity is reviewed. And the production restriction mechanism based on carbon emission, pollutant discharge and total energy consumption is gradually studied.

The plan defines the key areas and tasks of carbon emission reduction in the steel industry. According to the foregoing, carbon emission reduction will be mainly carried out through scrap utilization, fuel optimization, intelligent control, industrial coordination, green logistics, and strengthening carbon supervision.

In terms of the path to implementation, the above-mentioned people revealed that it will be realized from five aspects. Promote green layout, including optimizing industrial layout, increasing green logistics and promoting green products in the whole life cycle; Energy saving and energy efficiency improvement, including promotion of advanced and applicable energy saving and low carbon technology, improvement of waste heat self generation rate, digital and intelligent technology application; Optimize the energy consumption and process structure, including the optimization of the structure of raw fuel, encourage the development of short-process electric furnace steel, and improve the utilization of new energy and renewable energy; To build the industrial chain of circular economy, including regional energy and resource integration, utilization of solid waste resources and promotion of joint production of steel; Breakthrough low carbon technology, system construction and policy system support, mainly including carbon emission reduction objectives, carbon market, standard system, technological innovation, climate investment and financing, capacity-building, etc.

In addition, Internet plus and big data technologies should be used to build an information management and evaluation platform for the whole process of iron and steel to drive carbon emission and carbon emission reduction in the steel industry.

Yinruiyu, academician of Chinese Academy of engineering, suggested that the process structure of China steel industry should be adjusted in the process of reduction development. The long building materials should be produced by the whole scrap electric furnace process instead of the large products such as the screw steel and wire rod produced by the medium and small blast furnace and converter. That is, the steel plants around the city should be properly distributed and the urban mines should be used.

Li said that the distribution of productivity should be scientifically optimized and the phenomenon of "North Steel South transportation" should be changed. He suggested that the short-process steelmaking should be reasonably distributed in the long process areas such as Beijing, Tianjin, Hebei, the surrounding area and Yangtze River Delta. The fine material policy is adopted to stabilize the quality of raw materials, optimize coal blending, improve the proportion of pellet ore in ironmaking furnace, further reduce the solid combustion consumption, and then reduce the carbon emission from fossil energy consumption.

Luotiejun said that it should play a good role in regulating import and export, while maintaining export of high value-added products, reducing the export of general products and increasing the import of primary products such as billet and scrap steel. Promote the research and development of low carbon metallurgy and other transformative technologies, and improve the application of high-strength steel. For example, the research promotes the use of more than four grade threaded steel instead of three-stage threaded steel, reducing the total amount of steel used.

Luotiejun said that China steel has reached the key stage of transformation and upgrading to achieve high-quality development. Environmental protection pressure has been continuously increased, the price of imported raw fuel is still high, and enterprises are facing the risk of declining profit level. He suggested that the steel industry should continue to look inward, promote the construction of management system and management capacity, supplement the short board, improve the management level, meet the challenges of the international and domestic new environment, and achieve high-quality development.
