Electricity Grid Carbon Intensity and BF-BOF Decarbonization Technologies

Decarbonization is a key strategic objective for the steel industry. There is growing interest in DRP-EAF steelmaking, but BF-BOF steelmaking is anticipated to be retained at an annual capacity exceeding 1 billion tons. Therefore, it is essential to focus on reducing CO2 emissions from blast furnaces. This paper assesses two strategies to achieve reductions in BF CO2 emissions, i.e., usage of COG and H2 and optimization of ferrous burden and metallics. The electricity grid carbon intensity is included in the assessment as this will not be zero in the coming decades in most countries currently operating BF-BOFs.
