“Utilization of CO₂ in Reactive Carbon Capture: Evaluation of Deep Eutectic Solvents or Use in Electrochemical Pathways Under Flue Gas Conditions in a Flow Cell Configuration,” Miles Salas

SwRI has evaluated the use of Deep Eutectic Solvents (DESs) for use in an emergent CCUS technology called Reactive Carbon Capture (RCC), which aims to reduce the time, cost and complexity of traditional capture and utilization methods by eliminating intermediate steps and performing both processes simultaneously. This presentation covers the experimental work at SwRI from fundamental studies of select DES mixtures to operation of the DES mixtures in electrochemical RCC pathways in batch and flow configurations, with the goal of producing reduced carbon products. While RCC is currently a developing technology, R&D efforts have been accelerating to address market challenges.

“Utilization of Captured CO₂ to Graphene via Magnesiothermic Reduction: An Overview of a Novel CO₂ Utilization Process Including a Technoeconomic Analysis Based on Experimental Data and Process Simulations,” Michael Hartmann

SwRI has developed a novel process technology to convert CO₂ into different carbonaceous forms, including graphene, through a metallothermic reduction reaction. This presentation provides insight into the process through a discussion on lab-scale experimentation, analytical characterization, and the results of a detailed techno-economic analysis of the mass and energy balance of a pilot-scale process built from multiple simulations. Providing a means to integrate next-generation carbon capture utilization and storage (CCUS) technologies into high-value commercial markets could reframe them as lucrative opportunities.

Southwest Research Institute (SwRI) is an independent, nonprofit research and development organization that provides objective, multidisciplinary engineering and scientific services to government and industry clients worldwide, including translating greenhouse gas control concepts into deployable technologies.

SwRI combines expertise in reaction engineering, separations, process modeling, and pilot scale operations to advance CO₂ capture, conversion, and utilization pathways. Capabilities span bench to pilot design and construction, thermodynamic and kinetic evaluation, process simulation and techno economic analysis, and lifecycle and emissions assessments. We work with post combustion, pre combustion, and direct air capture streams, developing integrated solutions that include solvent/solid sorbent systems, advanced membranes, and catalytic and thermochemical CO₂ conversion.

Current conversion technologies for creating value from captured CO₂ include CO₂ to fuels and chemicals, mineralization and building materials, and advanced carbon materials such as graphene. By integrating capture, utilization, and systems analysis, we help clients reduce greenhouse gas emissions, de risk scale up, and improve the overall economics of greenhouse gas control technologies.
