The Imperative for Decarbonization
The steel industry is a significant contributor to global carbon emissions, traditionally relying on coal-fired blast furnaces that emit approximately 2.2 tonnes of CO₂ per tonne of steel produced . To align with net-zero targets by 2050, emissions from steel production must be halved by 2030.
Innovative Technologies Leading the Charge
The U.S. is witnessing a transformative shift in steel manufacturing, embracing technologies such as Direct Reduced Iron (DRI) processes powered by green hydrogen and electric arc furnaces (EAFs). These methods significantly reduce carbon footprints by utilizing renewable energy sources and recycled materials.
Startups like Electra and Boston Metal are pioneering electrolytic technologies that process low-grade ores using renewable electricity, offering scalable and modular solutions for green steel production .
