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. Coupling previously independent sectors like steel and chemical industry by CCU and power‐to‐X concepts is a promising approach to reduce CO2 emissions and fossil feedstocks. A five‐step approach to analyze and evaluate cross‐industrial concepts premised on CO2‐based syntheses with respect to future energy and market scenarios is developed.
