“…7 According to a report by the U.S. Department of Energy, the installation of a PCC plant using aqueous MEA solutions can increase the cost of electricity generation by up to 81−85% for a coal-fired power plant station. 8 Obviously, the high energy consumption of the CO 2 desorption process will be the main reason for growth, resulting in significant economic challenges for the large-scale development of CO 2 capture. 9 Over the past few decades, various efforts have been made to solve issues surrounding the high energy consumption of CO 2 desorption, especially regarding solvent optimization.…”

Catalytic CO 2 absorption−desorption has attracted broad interest due to its potential for improving CO 2 absorption efficiency and reducing energy consumption in CO 2 separation. However, most utilized catalysts are synthetic and pure, with the development of a natural and hybrid catalyst with acid−base bifunctional catalytic characteristics remaining a significant challenge. In this work, three fly ashes (1-FA, 2-FA, and 3-FA) with different compositions were used as catalysts, and the provided synergistic benefits in the overall MEA-CO 2 absorption−desorption processes were evaluated. The results showed that Brønsted acid sites, Lewis acid sites, and Lewis base sites were available on the fly ash surface, which provided proton and electron donation capability. 1-FA exhibited the best catalytic performance by enhancing the CO 2 cyclic absorption capacity by 6.7−26.1%, improving the CO 2 desorption rate with the highest value of 96.0%, and decreasing the sensible heat by 24− 28% compared to MEA as a blank run. Furthermore, 1-FA exhibited comparable catalytic performance to typical HZSM-5. The results of this study demonstrated that fly ash with zero cost and high availability could serve as a good hybrid catalyst candidate for CO 2 absorption and desorption.

“…CO 2 NCORD applies CO 2 capture cost technoeconomic models and data from peer‐reviewed literature to national‐scale databases of CO 2 emitters to estimate the amount of capturable CO 2 from each facility and the cost of capturing that CO 2 21 . The key parameters for CO 2 NCORD are the capture costs that are informed by various literature sources 22–33 . As CO 2 capture has yet to be deployed at scale, there is also industry dependent uncertainty on the cost of CO 2 capture.…”

The Intergovernmental Panel on Climate Change concludes that CO2 capture and storage (CCS) is critical for climate‐stabilizing energy transitions. In CCS, captured CO2 is sequestered in saline aquifers within sedimentary basins. The CO2 storage capacity and the rate of injection are functions of the geology of the saline aquifer, which is uncertain. To minimize impacts of this uncertainty, CCS projects could include backup plans, such as co‐locating geologic CO2 storage (GCS) sites with or near existing CO2‐enhanced oil recovery (CO2‐EOR) operations. These “stacked storage” projects could hedge against uncertainty in the saline formation performance because captured CO2 could be injected into either location in the event of unexpected events (e.g., the injectivity decreases). Here, we investigate the possibility and ramifications of developing CCS networks in Oklahoma that are amendable to stacked storage. We find that stacked storage is possible in Oklahoma but the counties with the lowest‐cost saline storage resources do not have existing CO2‐EOR operations. At the systems level, we find it is slightly more expensive (e.g., $1/tCO2 to $5/tCO2) to site GCS in counties with CO2‐EOR projects. This increased expense is largely due to increased CO2 transportation costs because hundreds of km of additional pipeline is required to capture CO2 from the lowest‐cost sources. Overall, our results suggest that it is optimal to build more pipelines and avoid injecting CO2 in some of the lowest‐cost saline storage resources, to enable capturing CO2 from the least‐cost sources. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…It has been reported that the levelized cost of CO 2 capture scales inversely with concentration. 28 The cost of separating CO 2 from dilute ue gas (<20% CO 2 ) is projected to be between $30-$70 per ton before compression can be performed, 26,[28][29][30][31][32][33] whereas during ethanol fermentation, nearly pure CO 2 is generated as a saturated gas at low to atmospheric pressure. 34 Largely related to separation costs, capturing CO 2 from combustion diluted ue gas requires around 10-fold more energy than from fermentation sources.…”

“…25,35,36 Collectively, the total levelized cost of sequestration for highpurity and dilute ue gas sources are generally around $30-$50 per t CO 2 and $70-$120 per t CO 2 , respectively. 25,30,33,37,38 To date, there have been numerous studies investigating the CCS potential at fossil energy plants, 32,33,39 industrial sectors, 28,30,40 and corn ethanol production. 30,34,37,[41][42][43][44][45] Prior studies of CCS applied to cellulosic biofuel production have been limited to processes involving thermochemical pretreatment and added fungal cellulase.…”
