“数”里行间透视“十四五”期间中国钢铁向“绿”而兴发展轨迹

Core Viewpoint - The establishment of China's first million-ton near-zero carbon steel production line in Zhanjiang marks a significant breakthrough in the green and low-carbon development of the steel industry, utilizing advanced hydrogen metallurgy technology to replace traditional coke and significantly reduce carbon emissions [1][4]. Group 1: Production Technology and Environmental Impact - The new production line employs hydrogen as the main reducing agent, achieving a carbon reduction of 50% to 80% compared to traditional methods [1]. - The hydrogen-based vertical furnace produces direct reduced iron with a metalization rate that meets expected targets, while efficient electric furnaces enhance energy utilization [1]. - The facility can reduce carbon dioxide emissions by 2,500 tons per day, making it the most environmentally friendly and lowest carbon emission smelting process currently available [3]. Group 2: Annual Carbon Reduction and Industry Contribution - The million-ton near-zero carbon steel production line is expected to reduce carbon emissions by over 3.14 million tons annually, equivalent to creating 2,000 square kilometers of forest [4]. - This project serves as a model for low-carbon transformation in the steel industry and contributes to high-quality development [4]. Group 3: Industry Trends and Goals - During the "14th Five-Year Plan" period, the steel industry is focusing on green transformation, with a significant increase in the number of green factories, totaling 126 new green factories from 2021 to 2024 [11]. - Key pollutants such as sulfur dioxide, particulate matter, and nitrogen oxides have seen significant reductions, with respective decreases of 28%, 26.7%, and 36.5% by the end of Q3 2025 compared to the end of 2021 [11]. - Water resource efficiency in the steel industry has improved, with water consumption per ton of steel decreasing from 2.50 cubic meters in 2021 to 2.33 cubic meters in 2024, a reduction of 6.8% [14]. Group 4: Energy Efficiency and International Competitiveness - The steel industry has initiated an extreme energy efficiency project, aiming for a total energy saving of approximately 10.5 million tons of standard coal and a carbon reduction of about 27.5 million tons by 2024 [16]. - The launch of the environmental product declaration platform for the steel industry has registered over 9,000 users, enhancing the international competitiveness of Chinese steel products by breaking down foreign green trade barriers [19].
