Decarbonization challenge for steel - McKinsey

2020-8-5  Steel can be produced via two main processes: either using an integrated blast furnace (BF)/basic oxygen furnace (BOF) or an electric arc furnace (EAF). While integrated players produce steel from iron ore and need coal as a reductant, EAF producers use steel scrap or direct reduced iron (DRI) as their main raw material.

Iron and Steel – Analysis - IEA

Demand for steel, which drives steel production, is a key determinant of energy demand and steel subsector CO 2 emissions. Global crude steel production increased by 5% in 2018 to reach 1 817 Mt, following 6% growth in 2017. Initial estimates suggest 3% growth in 2019. This follows a period of relatively flat demand from 2013-2016.
