Sustainable Mining and Metallurgy

The iron and steel industry has always been a major carbon emitter. Studying the “zero emission” of carbon in iron and steel production and promoting the development of hydrogen metallurgy technology is an important direction for the global iron and steel industry to achieve “carbon peak and carbon neutralization”. In this paper, the carbon emission of steel manufacturing process was analyzed, and the progress of hydrogen metallurgy technology at home and abroad was sorted out. The facts show that ‘replacing carbon with hydrogen’ is a breakthrough for the steel industry to greatly reduce carbon emissions. Based on the national policy orientation, the development of hydrogen metallurgy was prospected from the perspective of coordinated development of upstream and downstream industrial chains, and new development models of “hydrogen metallurgy+” were proposed. Based on the fact that the iron and steel industry was in the primary stage of green transformation, it was suggested that the development of hydrogen metallurgy in China should pay attention to the problems of hydrogen energy supply, iron ore resource grade, technology and standard, investment and financing.
