The winding road toward zero-carbon iron


The steel industry’s biggest product today isn’t steel — it’s carbon: roughly 1.8 tons of CO2 are released into the atmosphere for every ton of liquid steel produced on the still predominant, integrated production route. Globally, the sector is responsible for 7 to 10 percent of total CO2 emissions. A decisive shift away from carbon-based reductants to alternatives like hydrogen is inevitable — but it will have to come in stages.

Download this whitepaper to learn how the steel industry can harness the power of hydrogen to curb emissions and work its way toward net-zero carbon, using both cutting-edge as well as commercially available technology.
