APRIL 2023 - The Strength of Green Steel - Boosting competitiveness, decarbonizing supply

18 Apr 2023

Realizing the potential of green steel requires change at all stages of the supply chain, from the quality of iron ore, to the electrification of mining and processing operations, to zero-emissions transportation, to the availability of clean power in the manufacturing process. [...] The energy from metallurgical coal is used to reduce the intensity of the process is about one-eighth ore to molten pig iron (crude iron with higher PUBLIC POLICY FORUM 7 THE STRENGTH OF GREEN STEEL impurities and carbon content). [...] With hydrogen- For this reason, high-grade iron ore is required to limit impurities; based DRI the quality of the final product remains closely dependent on the (H-DRI), near grade of the iron ore input.8 zero This process, known by the shorthand DRI-EAF, emits on average emissions steel about 50 percent less CO2 per tonne of steel compared to the can be obtained integrated blast furnace method, w. [...] Marie, Ontario, and ArcelorMittal Dofasco in Hamilton are both transitioning to EAF with the assistance of more than $800 million in support from the governments of Canada The H-DRI and Ontario.11 The former will produce scrap- share of global based steel with its EAF,12 and the latter will steel production rely on its vertically integrated DR-grade could rise to iron ore from its pellet plant in. [...] Canada currently accounts for 2.5 percent of the world’s total iron of the world’s ore production, but its share of DR-grade ore total DR-grade export supply is already 10.7 percent.19, 20 iron ore supply PUBLIC POLICY FORUM 12 THE STRENGTH OF GREEN STEEL The Electrification Challenge o pull off these ambitious plans, each link of the supply T chain needs more clean electricity.
