“…Chemical absorption using amine solutions to recover CO 2 from flue gas streams is well-developed and deployed on a commercial scale. Also, polymeric membranes are being used commercially to separate CO 2 from syngas. − Reaching the full potential within the time limit imposed by the fact that CO 2 emissions are still increasing has motivated research to capture CO 2 directly from atmospheric air . Adsorption-based technologies are promising candidates that address these challenges: to efficiently capture CO 2 from a wide range of sources.…”

To rank the performance of materials for a given carbon capture process, we rely on pure component isotherms from which we predict the mixture isotherms. For screening a large number of materials, we also increasingly rely on isotherms predicted from molecular simulations. In particular, for such screening studies, it is important that the procedures to generate the data are accurate, reliable, and robust. In this work, we develop an efficient and automated workflow for a meticulous sampling of pure component isotherms. The workflow was tested on a set of metal−organic frameworks (MOFs) and proved to be reliable given different guest molecules. We show that the coupling of our workflow with the Clausius− Clapeyron relation saves CPU time, yet enables us to accurately predict pure component isotherms at the temperatures of interest, starting from a reference isotherm at a given temperature. We also show that one can accurately predict the CO 2 and N 2 mixture isotherms using ideal adsorbed solution theory (IAST). In particular, we show that IAST is a more reliable numerical tool to predict binary adsorption uptakes for a range of pressures, temperatures, and compositions, as it does not rely on the fitting of experimental data, which typically needs to be done with analytical models such as dual-site Langmuir (DSL). This makes IAST a more suitable and general technique to bridge the gap between adsorption (raw) data and process modeling. To demonstrate this point, we show that the ranking of materials, for a standard three-step temperature swing adsorption (TSA) process, can be significantly different depending on the thermodynamic method used to predict binary adsorption data. We show that, for the design of processes that capture CO 2 from low concentration (0.4%) streams, the commonly used methodology to predict mixture isotherms incorrectly assigns up to 33% of the materials as top-performing.

“…In fact, in a net zero world, we have to capture CO 2 from many different sources to ensure we close the carbon loop and, for example, use the CO 2 captured from waste incineration as a source of carbon for the chemical industry. In addition, given the lack of progress in decreasing our carbon emissions, there is an increasing need for technologies that reduce the CO 2 levels in the atmosphere 2, 3.…”

Decarbonisation from a variety of industrial and power emission sectors highlights a marked need for capture technologies that can be optimized for different CO 2 sources and integrated into an equally diverse range of applications of captured CO 2 as a feedstock. Some capture technologies are already operated at an industrial scale but may not be optimal for all required applications. Advanced tailored sorbent-based technologies allow flexible operation and reduced costs as they offer higher capture capacities and significantly lower energy penalties than the state-of-the-art systems. To accelerate the discovery, development, and deployment of novel advanced materials, it is critically important that efforts between experimentalists, theoreticians, and process engineers are coordinated. The PrISMa project addresses this challenge by integrating materials design with process design and environmental considerations to allow for tailor-making carbon capture solutions optimally tuned for local sources and sinks. In this article, we highlight some of the recent results obtained with the PrISMa platform.

“…1 Carbon Capture Utilisation and Storage (CCUS) is one of those technologies, where the utilisation of CO 2 has the potential double benet of not only reducing greenhouse gas emissions but also providing a nancial incentive to do so through the production of commodity chemicals. [2][3][4][5][6][7][8] Many different approaches have been trialed in order to convert CO 2 to fuels or other value-added products, including catalytic, electrocatalytic, photocatalytic and photoelectrocatalytic reactions. [9][10][11][12][13][14][15][16] In each of these cases, the high stability of the C]O bond (DG°= −394.36 kJ mol −1 ) and linear geometry of CO 2 poses a thermodynamic challenge, which needs to be overcome before it can be transformed to valuable compounds.…”
