A methodology for identifying suitable locations for the CO2-based production of olefins in Germany is presented. Based on electricity and CO2 requirements, locations are identified that can provide sufficient CO2 and renewable energy for the conversion of CO2 to olefins. In addition, the use of existing infrastructures is taken into account. The regional, technical renewable energy potential in Germany is sufficient to produce similar to 800 kt of olefins from CO2-based methanol per year in one plant. But the currently available CO2 point sources with high CO2 concentrations of around 100 % are not sufficient to meet the CO2 requirement of an 800 kt a(-1) methanol-to-olefins plant. If existing refineries are preferred due to existing infrastructure services, locations in the north of Cologne, in Lower Saxony, and in Brandenburg are particularly suitable. A full substitution of fossil olefins by CO2-based olefins is possible in Germany. The challenge is to provide sufficient renewable electricity for the production of H-2 with a low CO2 intensity.
