Recent Progress and Future Trends of CO 2 Breakthrough Iron and Steelmaking Technologies for CO 2 Mitigation

Iron and steel manufacturing is one of the most energy-intensive and CO2 emitting industries in the world. In order to contribute to the prevention of global warming, the reduction of CO2 from the steel works becomes a major issue imposed on the steel industry. A number of technologies have been developed in the past decade under worldwide CO2 breakthrough program for the reduction of carbon emissions. This chapter focuses on present needs, recent progress, and future trends of energy efficient new iron and steelmaking technologies. This study presents a comparative analysis of CO2 breakthrough programs including the present technological development and effects of application, economic feasibility, and environmental impact assessment. In addition, a brief analysis on ULCOS innovative ironmaking technologies has been done. Finally, significant CO2 reductions can be achieved by combining a number of the available energy efficient technologies with Bio-CCS.
