Exploration of material benefits highlights the need for identifying optimal trade offs between the properties of capture materials. In practice, this implies experimental (or computational, where experiments cannot be performed) measurements of all relevant material performance parameters. Property data can then be used to model and evaluate the performance of these materials in the given separation process using metrics such as energy consumption or CO 2 removal efficiency. To facilitate the application of the results in industry, frameworks for the selection of optimal materials that also cover technical, economic and environmental performance should be established.
