• Green Steel Insight Brief

    The process of making steel and shaping it into useful geometries requires high temperature and intensive energy consumption, which usually comes in the form of fossil fuels. On top of that, the steelmaking process requires breaking the chemical bond in iron ore to get access to pure iron, a reaction that requires a reagent to bind with oxygen. Broadly speaking, in the last 2,000 .
