Abstract：Focusing on "substituting carbon with hydrogen", the process of achieving carbon reduction in iron and steel industry was combed and traced. The way to achieve carbon emission reduction requires development of hydrogen metallurgy technology which uses hydrogen as reducing agent. At present, the world's main steel regions have developed two major hydrogen metallurgical technology routes, one is from fuel injection technology to hydrogen-rich smelting process of blast furnace, and the other is from non-coking smelting process to hydrogen direct reduction process. From the long-term plans of countries, developing hydrogen-based direct reduction processes and short electric furnace steelmaking processes are important directions of hydrogen metallurgical technology. At the same time, use of ash hydrogen such as coke oven gas is an important transition from "carbon substitution" to "hydrogen metallurgy" before the breakthrough of low-cost green hydrogen technology in China.
