CO2 reduction using a blast furnace utilizing hydrogen - dew point meter and oxygen concentration meter.

Introduction of measuring instruments for managing CO2 reduction using a carbon recycling blast furnace utilizing hydrogen.

Around us, we supply the highest quality steel in the world, including ordinary steel, special steel, ultra-high tensile steel plates, and electrical steel plates, to industrial machinery and automobiles, which are essential for a carbon-neutral society. We aim for "green steel," targeting decarbonized steelmaking by utilizing CCUS (carbon capture, utilization, and storage). As part of this effort, the development of steelmaking technologies using hydrogen is underway. One example is hydrogen reduction technology, which synthesizes methane from carbon dioxide and hydrogen emitted from the reduction furnace (methanation) and uses it as a reducing agent to remove oxygen from iron ore (Fe2O3) used in blast furnaces. By reducing low-grade iron ore solely with hydrogen instead of coal, we can minimize carbon dioxide emissions during steel production. In addition to hydrogen-based developments, efforts are also being made to produce steel products by rapidly melting direct reduced iron and scrap in electric furnaces.
