Maximizing biogenic carbon utilization by direct hydrogenation of biogas CO2 into electro-fuels

This research project explores a novel process for converting biogas CO2 directly into methanol and hydrocarbon electrofuels using hydrogen from renewable electrolysis, avoiding conventional CO2 separation. The approach not only reduces energy demand but also utilizes biogenic CO2, enhancing the overall valorization of biogas. The work involves the synthesis, characterization, and lab-scale reactor testing of both conventional and emerging catalysts under realistic conditions, including the presence of biogas impurities. A key point is to develop novel catalysts that are stable during process conditions and can be effectively regenerated. Process simulations will estimate energy and cost savings, carbon utilization efficiency, and feasibility. Industrial partners will provide expertise and input to ensure industrial relevance. The project aims to develop impurity-tolerant catalysts, demonstrate improved carbon conversion, and support renewable electrofuel production.
