What are the good ways for the steel industry to reduce carbon emissions?

As the industry with the largest carbon emissions, what are the good methods and paths for the steel industry to reduce carbon emissions?

One of the most direct ways to promote low-carbon development of the steel industry is to improve smelting technology and reduce energy consumption. At present, some research institutions and steel companies in my country are vigorously developing low-carbon processes. Qu Xiuli, vice president and secretary-general of the China Iron and Steel Association, said that it is necessary to focus on the upstream and downstream of the steel industry to promote low-carbon products, "further optimize the raw material process and energy structure, break through the bottleneck of low-carbon technology, and promote non-fossil energy, especially hydrogen. It can be applied in the steel industry to encourage steel companies to introduce the concept of green development throughout the product life cycle, vigorously promote green design products, and guide the upgrading of steel use in downstream industries."

In addition to upgrading the process, iron and steel enterprises use waste heat to increase the proportion of self-generation, which can also reduce energy consumption and develop low-carbon. Zhao Xizi, the founding honorary chairman of the All-Union Metallurgical Chamber of Commerce, said: "If the proportion of self-generated electricity is 50%, the electricity consumption per ton of steel will be about 455 kWh, which will reduce social electricity consumption by 226.6 billion kWh throughout the year. It is 2.4 times that of the Three Gorges Power Plant, and it reduces 240 million tons of carbon dioxide emissions every year. If it is increased to more than 50%, it will be even more remarkable."
