CO2 Ultimate Reduction System for Cool Earth 50
This project aims to fundamentally reduce CO2 emissions from the blast furnaces of integrated steelworks and contribute to the prevention of global warming by developing technology to reduce the amount of CO2 generated at blast furnaces as well as technology to separate and capture generated CO2 with each technology cutting CO2 emissions by 10% and 20% respectively. In this project, we have been working on the development of two types of technologies: (1) technology to reduce iron ore by amplifying hydrogen contained in high-temperature coke oven gas generated during coke production, and using that hydrogen as a partial replacement for coke as a reduction technology in blast furnaces using hydrogen; and (2) an innovative technology to separate and capture CO2 using unused exhaust heat within a steelworks to separate CO2 from blast furnace gas. The steel industry is working in unity to ultimately establish technology that would enable the reduction of CO2 emissions by approximately 30% compared with the current level of total emissions at steelworks.
