The steel industry is promoting green and low-carbon transformation

The National Development and Reform Commission, the Ministry of Industry and Information Technology and other departments issued the "Several Opinions on strict energy efficiency constraints to Promote energy conservation and carbon Reduction in Key Areas" proposed: By 2025, through the implementation of energy conservation and carbon reduction actions, the proportion of production capacity of key industries such as steel and data centers reaching the benchmark level will exceed 30%, the overall energy efficiency level of the industry will be significantly improved, carbon emission intensity will be significantly reduced, and the capacity for green and low-carbon development will be significantly enhanced.

"At present, the proportion of the main processes in the steel industry to reach the benchmark value of energy efficiency is still a large gap from the policy requirements of more than 30% of the capacity to reach the benchmark level of energy efficiency in 2025." Fan Tiejun, president of the Metallurgical Industry Planning and Research Institute, pointed out that in 2022, due to the decline in steel demand and the overall capacity utilization rate, the comprehensive energy consumption per ton of steel increased slightly year-on-year. From the current stage, the total energy consumption of China's steel industry is large, and the energy consumption structure is biased toward coal, and the pressure of energy transformation is greater than that of other industries.

At the end of 2022, the "Energy efficiency Benchmark three-year Action Plan" for the steel industry was officially launched, and the extreme energy efficiency project entered the substantive implementation stage. Cisa's "Double carbon best Practice energy efficiency Benchmarking Demonstration Plant" cultivation work will strive to achieve the level of energy efficiency benchmarking of 0.8 million tons to 100 million tons in 2023, 150 million tons to 200 million tons in 2024, and 200 million tons to 300 million tons in 2025.

Shougang Stock Qian Steel Company, Jingtang Company and other 21 steel enterprises were selected as the first batch of "double carbon best practice energy efficiency benchmark Demonstration Factory" cultivation enterprises. "We take building an extremely energy-efficient operation system as a strategic starting point to promote the goal of 'two-carbon'." Liu Jianhui, general manager of Shougang, said that on June 25 this year, Shougang's ultimate energy efficiency improvement project launch meeting was held, and in cooperation with the Metallurgical Industry Planning and Research Institute, the energy efficiency benchmarking action Plan and the three-year Action Plan for energy efficiency Improvement will be formed around the four directions of structural energy saving, technical energy saving, management energy saving and system energy saving. Strive to build Shougang Co., Ltd. into the first batch of domestic benchmark energy efficiency demonstration enterprises.

Ding Zhijun revealed that the next step, the Ministry of Industry and Information Technology will continue to implement the "Industrial energy Efficiency improvement Action Plan", in the steel industry energy saving and energy efficiency improvement, focus on three aspects of work: first, the promotion and application of advanced energy saving technology as a starting point, the release of industrial and information field energy saving and carbon reduction technology equipment catalog, promote technology energy saving; The second is to strengthen the energy efficiency standards as the key, continue to carry out the energy efficiency "leader" enterprises and green factories construction, promote the management of energy conservation; The third is to accelerate the construction of industrial green microgrids, improve the level of industrial energy electrification, and promote structural energy conservation.

Actively yet prudently promote "dual carbon"

The steel industry is the key area and the main responsibility to achieve the goal of carbon neutrality. Due to the influence of energy resources endowment, China's steel industry has a high carbonization energy structure, and has the characteristics of large output, large number of enterprises, and complex carbon emission mechanism. According to the overall judgment of the industry, China's steel industry to peak carbon neutral has to go through four stages: peak, carbon reduction, decarbonization and neutralization.

Hesteel Group is brave to "ride the tide" and promote the change of energy structure. In May this year, the first phase of the world's first 1.2 million tons of coke oven gas zero reforming "hydrogen metallurgy Demonstration project" achieved stable production in Zhangxuan Technology of HeSteel, and the indicators reached the international advanced level. In this project, zero reforming hydrogen metallurgy technology of high pressure shaft furnace using coke oven gas as reducing gas was first adopted, and the ratio of hydrogen to carbon in the process gas was more than 8∶1. Compared with the same scale of "blast-converter" long process production, carbon dioxide emissions are reduced by 800,000 tons per year, or 70%.
