BHP has launched a comprehensive steel decarbonization program supporting customers across multiple technology pathways. The initiative includes modified blast furnace trials achieving 5% to 35% emissions reductions through fuel substitution & carbon capture, hydrogen-based direct reduced iron demonstrations offering 85% to 95% reductions, & emerging electrochemical research. Projects span collaborations ArcelorMittal, HBIS Group, JSW Steel, POSCO, & others across Europe, Asia, & Australia. Key challenges include renewable energy costs rendering hydrogen pathways economically unviable & carbon capture infrastructure deficits constraining commercial deployment despite technical feasibility demonstrations.
