Tetrameric self-assembling of water-lean solvents enables carbamate anhydride-based CO2 capture chemistry
Abstract Carbon capture, utilization and storage is a key yet cost-intensive technology for the fight against climate change. Single-component water-lean solvents have emerged as promising materials for post-combustion CO 2 capture, but little is known regarding their mechanism of action. Here we present a combined experimental and modelling study of single-component water-lean solvents, and we find that CO 2 capture is accompanied by the self-assembly of reverse-micelle-like tetrameric clusters in solution. This spontaneous aggregation leads to stepwise cooperative capture phenomena with highly contrasting mechanistic and thermodynamic features. The emergence of well-defined supramolecular architectures displaying a hydrogen-bonded internal core, reminiscent of enzymatic active sites, enables the formation of CO 2 -containing molecular species such as carbamic acid, carbamic anhydride and alkoxy carbamic anhydrides. This system extends the scope of adducts and mechanisms observed during carbon capture. It opens the way to materials with a higher CO 2 storage capacity and provides a means for carbamates to potentially act as initiators for future oligomerization or polymerization of CO 2 .
Screening-Level Cost Estimates for CO2 Capture and Transportation: CarbonSAFE Illinois - Macon County (Task 10)
This report presents a screening level study of cost estimates for transporting CO 2 via pipeline from five separate sources to a proposed injection well near Mt Auburn IL (Christian County). The basis for the cost estimates is also presented.
Pulverized Coal CO2 Capture Retrofit Database
This tool provides high-level analysis on the incremental costs for retrofitting pulverized coal plants with carbon dioxide capture and/or compression systems. Options are available to include costs of other technological improvements that would be required to comply with various environmental regulations when installing carbon capture technology. This model is based on the NETL report "Eliminating the Derate of Carbon Capture Retrofits." (2023).
