Abstract：Hydrogen energy is the most powerful clean energy in the 21 st century,and is an important part of our country's future energy system. Building a new steel energy system "replacing carbon with hydrogen" is an important direction of realizing double carbon target in China′s iron and steel industry. For hydrogen energy based hydrogen metallurgy technology,the principle and technological process,the hydrogen metallurgical products,key functional units are interconnected,hydrogen shaft furnace and other key equipment,plant layout,technical and economic indexes and operation cost estimation and CO2 emissions were discussed,such as the system structure and key technologies of hydrogen metallurgical engineering. The engineering practice shows that the hydrogen metallurgy process with hydrogen-rich coke oven gas as reduction gas source,using gas reforming and gas base direct reduction iron making technology,using oxidized pellets as raw material,completely eliminating the use of coke,coal and sinter,reducing the use of carbon from the source,and greatly reducing the generation and emission of pollutants. No sintering,coking process,the general layout is compact,greatly saving land. Hydrogen metallurgy with coke oven gas as gas source has some advantages in operational cost. Based on the estimation of technical and economic indicators,hydrogen metallurgy based on hydrogen-rich coke oven gas can achieve 58.8% reduction in carbon emission per ton of iron compared with blast furnace ironmaking process. Hydrogen metallurgical process can not only provide high-quality pure hot metal for the subsequent electric furnace steelmaking,but also play a significant role in improving the quality of Chinese iron and steel products,and lay a solid foundation for the future development of green,low carbon and high quality of iron and steel industry.
