Steel Decarbonization Depends on Scrap and Electric Arc Furnaces, Not Hydrogen

Summary

The article argues that steel decarbonization is fundamentally about transitioning to scrap-based electric arc furnace production and retiring coal-based blast furnaces, not about creating a hydrogen demand market. It critiques the framing of steel decarbonization as a hydrogen story, noting that hydrogen-based direct reduced iron (DRI) faces significant cost, infrastructure, and scalability challenges. The piece emphasizes that scrap recycling and electric arc furnaces are the primary decarbonization levers, while clean primary iron production (via hydrogen or other methods) serves only a bounded, contested market for high-grade steel applications where scrap quality is insufficient.
