Low Energy CO2 conversion and utilization in steel industry
Abstract
According to EUROFER, CO2 emission from steel industry have to be decreased by at least 80% until 2050 (based on 1990). This level cannot be reached solely by process development as European steel making routes are already operated at their physical and thermodynamic limits. A possibility to meet this target is represented by converting emitted CO2 into methane which is re-used in the steel mill so establishing a circular carbon economy. This exploratory project aims to answer the following question: Can methane be used in steel industry as a substitute for the reducing agents coke & coal? What are the consequences of methane usage regarding the energy balance of a steel mill? It is envisaged to subject exhaust gases from steelworks to methanation best without any energy intensive CO2 capture technology. Therefore, biological techniques will be considered as the preferred methanation technology. The following options will be investigated: - Biological CO2 reduction with H2 to methane in subsurface gas reservoirs. - Bioelectrochemical CO2 reduction to methane
