(400c) Integrated Capture and Conversion of CO2 into Materials (IC3M); A Multi-Product Technology for Ccus

The capture, sequestration and utilization of CO₂ are needed to achieve the global goal of decarbonization. The United States Department of Energy (DOE) has recently prioritized utilization of CO₂ by recycling it into fuels and chemicals as a part of a broader negative-emissions strategy, though the energy and capital costs associated with capturing, purifying and compressing CO₂ are often overlooked. In this presentation, we describe a dynamic and flexible technology that couples solvent-based CO₂ capture with catalytic upgrading CO₂ captured in solution to produce low-carbon fuels and chemicals such as methane or methanol with high atom and energy efficiency. The IC³M approach provides reduced costs while improving efficiency of detached capture and conversion processes. IC³M allows for multiple products to be made from a single solvent process by simply changing the reagent co-feed and/or catalyst. The ability to produce multiple products allows IC³M to change to market needs providing superior economic adaptability that single product technologies cannot achieve. We describe here, results from a multidisciplinary study that couples solvent-based capture and catalytic upgrading of CO₂ that is captured in solution to make multiple products. We provide a discussion of the energetics and economics of IC³M and its viability in the global decarbonization market.
