Low Energy CO2 conversion and utilization in steel industry

Steel production is one of the most energy-intensive production processes in which large quantities of carbon dioxide (CO2) are released as a result of the process. Energy rich steel mill gases contain significant amounts of CO, CO2 and H2 which can be used for biological methanation. The project goals are therefore: - to evaluate the technical feasibility of up to 10 % CO2 emission reduction with biological CO2 conversion to methane - to use untreated steel mill gases in the biological methanation process - to compare underground CO2 conversion with bioelectrochemical CO2 conversion - to evaluate the usage potential of methanation product gases in a steel mill
