We design a CO₂ Capture, Utilization, and Sequestration (CCUS) supply chain network with minimum cost to reduce stationary CO₂ emissions and their adverse environmental impacts in the United States. While doing so, we consider simultaneous selection of source plants, capture technologies, capture materials, CO₂ pipelines, locations of utilization and sequestration sites, and amounts of CO₂ storage. The CCUS costs include the costs of flue gas dehydration, CO₂ capture, compression, transportation and injection, and revenues from CO₂ utilization through enhanced oil recovery (CO₂-EOR). The dehydration, capture, and compression costs are derived using advanced modeling, simulation, and optimization of leading CO₂ capture processes. Our results suggest that it is possible to reduce 50–80% of the current CO₂ emissions from the stationary sources at a total annual cost ranging $58.1–106.6 billion. Furthermore, it is possible to generate $3.4–3.6 billion of revenue annually through supplying CO₂ for CO₂-EOR. Overall, the optimal CCUS supply chain network would correspond to a net cost of $35.63–43.44 per ton of CO₂ captured and managed. Such a cost-effective network for CO₂ management is attained due to (i) using novel materials and process configurations for CO₂ capture, (ii) simultaneous selection of materials and capture technologies, (iii) CO₂ capture from diverse emission sources, (iv) CO₂ utilization for enhanced oil recovery, and (v) nationwide CO₂ storage. Results for the regional and statewide (Texas) CCUS are also favorable.
