On December 23, China's first million-tonne near-zero-carbon steel production line was fully commissioned at Baosteel Zhanjiang Iron and Steel Co., Ltd., marking a major step forward in the steel industry's low-carbon transition.
The project uses China Baowu's proprietary hydrogen-based metallurgy and electric smelting (HyRESP) technology, enabling a fully integrated short-process route to produce high-grade flat steel products with zero-carbon emissions.
The line combines the country's first million-tonne hydrogen-based shaft furnace with newly built electric arc furnace and continuous casting facilities. Construction of the new units began in April 2024. Using hydrogen-based direct-reduced iron and scrap steel as raw materials, it produces low-emission slabs that are rolled into low- and near-zero-carbon steel products.
Compared with the traditional "blast furnace + basic oxygen furnace" process, the project is expected to cut carbon emissions by 50–80%, reducing CO2 emissions by up to more than 3.14 million tonnes per year.
