Insight 1: Multiple technologies for producing lower carbon steel are here — including electrolysis and clean hydrogen — with each presenting its own challenges.
For many years, steelmaking has followed a consistent, two-step process: First, iron ore is mined and mixed with coal, as well as other substances, to make molten iron. This process most often happens using highly polluting blast furnaces. Some 90% of steel-related emissions come from this first iron-producing step.
