NEDO Completes Test Operations of CO2 Emissions Reduction Capabilities in World's Largest Experimental Blast Furnace

– Will establish a technology capable of 30% reduction in CO2 emissions during iron-making process –

New Energy and Industrial Technology Development Organization (NEDO)

NEDO, together with Kobe Steel, Ltd.; JFE Steel Corp.; Nippon Steel & Sumitomo Metal Corp.; Nippon Steel & Sumikin Engineering Co., Ltd.; and Nisshin Steel Co., Ltd., has completed test operations of the CO2 emissions reduction capability of the world’s largest experimental blast furnace (volume of 12m3). The blast furnace was constructed in FY2016 inside of Kimitsu Works, Nippon Steel & Sumitomo Metal.

During the test, operations a total of four trial was conducted to verify two types of technology: one which reduces CO2 emissions from the blast furnace by utilizing hydrogen as reductant for iron ore, and one which captures CO2 from the gas emitted by the blast furnace.

Based on the results of these test operations, the a technology solutions that reduce and capture CO2 are bigger effets than they did before. The successes of the these operations represent a major step forward in achieving the goal of a 30% reduction in the amount of CO2 emitted during the iron-making process.
