Direct Reduced Iron (DRI) production using the Coal-based Direct Reduction (Coal-DRI) process is typically employed in the steelmaking industry to obtain metallic iron from iron ore without melting the ore. This process uses non-coking coal as a reductant in a solid-state reduction of iron oxides. The DRI produced is often used as a feedstock for electric arc furnaces in steel mills, wherein it is melted to produce steel. When using life cycle inventory (LCI) data of the Coal-based Direct Reduction (Coal-DRI) routes, ensure that the data is applicable to the specific geographic location and technological context of your assessment. The LCI data should be consistent with the average operating data of demonstration projects in China. When considering COG-DR and H-DR routes, be aware that the data for these processes is estimated based on Coal-DR combined with literature data and therefore may require additional validation. The projection of these routes for large-scale industrial application should be made with caution due to technological and scale extrapolation risks.
