SUMMARY:Evaluation of carbon dioxide emission reduction potential of voestalpine Stahl Linz by Transitioning to DR-EAF steel production with a m.simtop digital twin
DESCRIPTION:Steel plants in Europe are committed to reduce their carbon emissions by 80-95% by 2050 in accordance with the EU Climate targets. Today the majority of the global steel production is performed via the conventional BF-BOF route and responsible for 7% of global carbon dioxide emissions. While most of European steel plants are already running at a high efficiency through various optimization strategies, the transition towards more sustainable steel production routes such as the DR-EAF route is needed to further reduce the carbon emissions. 
In this study the potential reduction of carbon dioxide emission for the voestalpine Stahl Linz plant is simulated by partially switching the steel production of one BF to a DR-EAF. For the assessment of the theoretical carbon dioxide emission reduction, a digital twin of the voestalpine Stahl Linz site was implemented in its as-is conventional BF-BOF route set up and compared to a theoretical substitution one of voestalpine’s BF by a DR-EAF plant. 
Therefore, the voestalpine Stahl Linz plant is depicted through the m.simtop metallurgical process modelling library in form of a flowsheet and validated with process data. In a subsequent step the flowsheet was modified by removing one BF and introducing a DR and an EAF to form a hybrid steel plant.  For further CO2 reduction the use of coke oven gas at the blast furnace or in the DR process was simulated and the changes in the energy network of the steel plant are investigated.
