Methodology for the evaluation of CO2-based syntheses by coupling steel industry with chemical industry

Carbon-intensive sectors like steel or chemical industry need to reduce their emissions and their dependence on fossil feedstocks to help reaching climate goals. Coupling previously independent sectors by carbon capture and utilization and power-to-X technologies are promising concepts. Within the Carbon2Chem project, a generic approach for the evaluation of various plant configurations with respect to future market and energy scenarios is presented. Economically and ecologically favorable concepts for the recycling of steel mill gases to valuable products, especially methanol, by integrating high amounts of renewable energies are identified for the year 2030
