Green Steel Production

Revolutionary steel production using hydrogen instead of coal, eliminating up to 95% of CO₂ emissions from steelmaking. Direct reduction with green hydrogen replaces traditional blast furnaces, producing water vapor instead of carbon dioxide.

How It Works

Green steel production replaces coal-based blast furnaces with hydrogen-based direct reduction technology. Iron ore is reduced using hydrogen gas produced from renewable electricity through electrolysis, creating iron sponge that is then processed in electric arc furnaces. The process eliminates coal entirely, with hydrogen combining with oxygen in iron ore to produce water vapor instead of CO₂.

Advantages

Eliminates 95% of steel production emissions, the largest industrial CO₂ source. Compatible with existing steel infrastructure with modifications. Creates pure iron with fewer impurities than traditional methods. Enables steel recycling integration with electric arc furnaces. Positions steel industry for carbon-neutral future.

Challenges

Requires massive renewable energy infrastructure for hydrogen production. Currently 20-30%^[1] more expensive than traditional steel. Limited by hydrogen availability and storage challenges. Needs significant capital investment for plant conversions. Technology still scaling from pilot to commercial deployment.
