On the afternoon of the specified date, a summary and discussion meeting on the acceptance phase of the "Ultimate Energy Efficiency Project for Steel" was held in Beijing. Attending the meeting were Jiang Wei, Deputy Secretary of the Party Committee, Vice President, and Secretary-General of the China Iron and Steel Association; Xiao Bangguo, Vice President of the Metallurgical Industry Planning and Research Institute; Fu Jing, Deputy Director of the Metallurgical Industry Information Center; representatives from steel enterprises, experts, scholars, and others. The meeting was chaired by Zhang Yongjie, Special Advisor to the Steel Association. The meeting introduced the stage acceptance status of the "Double Carbon Best Practice Energy Efficiency Benchmarking Demonstration Enterprises" and the issues discovered during the acceptance process. It also invited representatives from enterprises and industry experts to exchange experiences and provide constructive suggestions on the further development of the ultimate energy efficiency project in the future.

As reported, as of now, a total of enterprises have completed on-site acceptance, including Shougang Jingtang, Zhanjiang Iron and Steel, HBIS Shijiazhuang Iron and Steel, Ningbo Iron and Steel, Baosteel's Baoshan Base, Angang Steel's Bayuquan Branch, Shougang Qian'an Steel, and Magang. These involve 10 coke ovens, 10 blast furnaces, 10 converters, and 10 electric arc furnaces. Zhanjiang Iron and Steel, Shougang Jingtang, HBIS Shijiazhuang Iron and Steel, Ningbo Iron and Steel, and Baosteel's Baoshan Base have completed energy efficiency benchmarking and demonstration acceptance on the official website of the China Iron and Steel Association, involving 10 million tons of crude steel production, with HBIS Shijiazhuang Iron and Steel being a fully scrap-based electric arc furnace short-process enterprise.

This year marks the third year of the Energy Efficiency Benchmarking Three-Year Action Plan. Enterprises that participated in the first batch and some of the second batch have already witnessed the beauty of spring blossoms and autumn fruits. The completion of on-site inspections by these enterprises is one of the landmark and phased achievements of the Energy Efficiency Benchmarking Three-Year Action Plan, Zhang Yongjie summarized at the meeting.

Fu Jing introduced in her report the overall energy efficiency of enterprises that have been publicly disclosed for each process: the average energy consumption for the coking process is . kilograms of standard coal per ton; the average energy consumption for the blast furnace process is . kilograms of standard coal per ton; the average energy consumption for the converter process is -. kilograms of standard coal per ton; the average energy consumption for the electric arc furnace process with full scrap steel is . kilograms of standard coal per ton, and the average energy consumption for the electric arc furnace process with hot charging of iron and water is . kilograms of standard coal per ton. She summarized the issues discovered during on-site acceptance and data verification, introduced the key content of data verification, and explained the management of data after public disclosure.

Jiang Wei emphasized in his concluding remarks, "One effort, one gain. Over the years, the steel extreme energy efficiency project has been continuously 'growing' with everyone's joint efforts. In the process of advancement, we have been solving new problems and overcoming new difficulties. We are increasingly confident in making the extreme energy efficiency work meticulous and solid, which will play a positive role in the next step of including the steel industry in the carbon market and in the energy benchmarking and potential tapping work among enterprises. In the list of the first batch of cultivation enterprises, I see the presence of many small and medium-sized enterprises, indicating that more and more steel companies are recognizing the value of energy-saving transformation and understanding that the implementation of extreme energy efficiency work can bring tangible benefits to the enterprise. Now, the extreme energy efficiency project has entered a new stage, and the energy efficiency cost reduction and carbon reduction effects of enterprises have become apparent through the acceptance process."

According to his introduction, from January to February of this year, the total energy consumption of key statistical steel enterprises amounted to 125.6 million tons of standard coal, a decrease of 4.7% year-on-year; the comprehensive energy consumption per ton of steel was 551.3 kilograms of standard coal, a decrease of 2.0% year-on-year. In terms of process energy consumption, the energy consumption of sintering, ironmaking, converter steelmaking, electric furnace steelmaking, and steel processing in key statistical steel enterprises decreased by 1.7%, 2.3%, 1.8%, 1.7%, and 2.2% respectively compared to the same period last year, while the energy consumption of coke oven process increased. According to the data from the energy efficiency data reporting system, among the 90 enterprises participating in the cultivation, the energy consumption of coke oven process decreased by 2.2%, the blast furnace process by 3.6%, and the converter process by 3.7% in the first half of this year compared to the benchmark year, with more significant declines.

Jiang Wei said, "The original intention of pursuing ultimate energy efficiency is to enhance the energy efficiency level of the steel industry. We must persevere, refine and summarize some good energy-saving technologies, and promote their application across the entire industry."
