Steelmaking remains a relatively energy-intensive process with considerable GHG emissions. Traditional processes require the use and combustion of coal and remain quite energy- and emissions-intensive. There is no single solution for the decarbonization of the steel industry. However, key pathways include:
- Alternative iron and steelmaking processes;
- Hydrogen injection into the blast furnace;
- Utilizing clean electricity sources;
- Increased use of scrap;
- Integrating hydrogen use into existing processes.
Technology development is also underway to provide an infrastructure capable of supplying clean hydrogen and renewable electricity to help enable the industry to decarbonize its operations.
