Evaluation of Innovative Steel Production Technologies

Article looks for carbon emission reduction beyond the blast furnace route

  • Publications 01.12.2014

The steel industry, one of the most energy intensive industries in Germany, is expected to contribute to the national climate protection efforts. Since the established coal-based steel production routes are close to reaching maximum efficiency, additional carbon (CO2) emission reduction in long term can only be achieved via innovative technologies. The article "Techno-economic evaluation of innovative steel productiob technologies" assesses three innovative primary steel production technologies in comparison to the established blast furnace route. Apart from technical and economical criteria, the comparative assessment includes social, safety-related and ecological criteria. The technologies in scope are the blast furnace route in combination with carbon capture and storage (CCS), the direct reduction with hydrogen and the electrolysis of iron ore, also called electrowinning.
