Carbon dioxide (CO2) emissions which mainly come from the combustion of fossil fuels are currently the biggest contributors to global warming. The level of CO2 in the atmosphere has been in a rapidly increasing trend for over 100 years and is currently at 410 ppm. Carbon capture technologies are an important way to reduce emissions from industrial processes or electricity generation by capturing and storing CO2 before it is released into the atmosphere. CO2 electrolyzers use this captured CO2 to produce valuable chemical products (e.g., formic acid, carbon monoxide, methanol, and others). This technology simultaneously remediates CO2 emissions while producing products with economic value[3].

The objective of my PhD within ELCAT is to further develop the electrochemical reactor design for CO2 reduction towards higher technology readiness levels. More research is needed to optimize design parameters such as channel dimensions besides ensuring long term stability. Furthermore, the influence of different contaminants in industrial CO2 streams will be investigated since current electrolyzer research has been almost exclusively done with pure CO2-streams. Overall, the research will be focused on reactor design and configuration.
