Abstract

The commercial deployment of cost-effective carbon capture technology is hindered partially by the lack of a proper suite of materials-related standards, data, and measurement methods, which would provide critical information for the systematic design of CO2 separation materials. Based on a literature search and conversations with the carbon capture community, this review documents the standards, data, and metrology needs for carbon capture materials: solvents, solid sorbents, and membranes. Further, we highlight current activities aimed to address some of these research gaps. The review reveals that although solid sorbents are considered to have great potential to reduce carbon capture cost, there is no consensus on the experimental parameters to be used for evaluating sorbent properties. Another important research need relates to the development of in-situ experimental tools for the characterization of solid porous materials during CO2 adsorption, and computational methods that would enable a materials-by-design approach for their development.
