Steadily implement carbon reduction in the steel industry

2023-04-19

At the recently held 2023 (<>th) China Iron and Steel Development Forum, relevant people pointed out that the steel industry will continue to promote green, low-carbon and ultra-low emission transformation, and actively take action in carbon emission management, energy structure adjustment, hydrogen metallurgy application and other aspects to promote China's steel industry to achieve green and low-carbon transformation. China's huge steel industry has formed a strong support for global manufacturing operations, real estate and infrastructure construction.

Data show that in 2022, China's crude steel production will be 10.13 billion tons, accounting for a relatively high proportion of global crude steel production; a total of 2 million tons of crude steel production capacity in the country has completed the whole process of ultra-low emission transformation and publicized, and 07 million tons of crude steel production capacity has completed key engineering transformations such as sintering pellet desulfurization and denitrification, and material yard closure, which account for two-thirds of the country's total production capacity. In the first three months of this year, about 4 million tons of crude steel production capacity completed the whole process of ultra-low emission transformation. The carbon reduction of the steel industry has achieved phased results. Through continuous research and development of low-carbon technologies, optimization of process structure, and efforts in the construction of green and low-carbon industrial chains and global low-carbon industry innovation cooperation, China's steel industry will go more and more smoothly on the road to the goal of "dual carbon".

However, there are some issues that cannot be ignored either. With the enhancement of resource and environmental constraints, especially the promotion of the "dual carbon" process, the absolute scale of China's steel industry corresponds to the pressure from the industry's carbon reduction. In 2022, the carbon emissions of China's steel industry will be about 18.23 billion tons, accounting for more than 15% of the country's total carbon emissions, and it is the industry with the largest carbon emissions among the 31 categories of manufacturing. If the carbon emissions of the steel industry cannot be reduced as soon as possible, in addition to directly affecting the international competitiveness of steel products through carbon cost improvement, it will also affect the development of downstream manufacturing and construction industries through carbon footprint.

To solve the problem of carbon emissions in the steel industry is not to "reduce production capacity" or "turn it off", but to meet the demand for steel products in related fields of the national economy, make the industry run more low-carbon, and eventually transform the steel industry into a clean material industry. According to the "Carbon Neutrality Vision and Low-carbon Technology Roadmap of the Steel Industry" released by the China Iron and Steel Association, the "dual carbon" process of China's steel industry will be divided into four stages, and carbon peaking will be achieved before 2030; deep decarbonization between 2030 and 2040; 2040-2050 sprint to limit carbon reduction; Achieve carbon neutrality from 2050 to 2060.

In order to achieve these goals, we must vigorously promote the research and application of hydrogen-rich smelting technology. At present, Baowu has completed a 400 cubic meter low-carbon metallurgical blast furnace and the first phase of HBIS's 120.<> million ton hydrogen metallurgy demonstration project has been fully completed. Second, efforts should be made to increase the proportion of short-process steelmaking. For example, Jiangxi, Sichuan and Henan have made it clear that electric furnace short-process steelmaking is no longer included in the "two highs" project for management. Third, we must continuously improve the market mechanism for the steel industry to participate in carbon trading. Steel companies are carrying out preliminary planning, data statistics, staffing and other preparatory work. Major domestic steel companies such as Baowu, HBIS and Angang have issued green bonds to attract "living water" for enterprises to reduce carbon emissions. In addition, from the perspective of carbon trajectory, domestic steel companies are vigorously carrying out carbon reduction cooperation with downstream enterprises such as automobiles and home appliances, reducing the full life cycle carbon emissions of downstream related products by building a green and low-carbon steel supply chain, and helping downstream enterprises break through carbon barriers in international trade.
