Abstract	Carbon Capture and Sequestration (CCS) offers the possibility of significant reduction of CO2 emission from power plants. Specifically, adsorption by nano-porous materials offers the potential for efficient capture of CO2 at point of origin in a post-combustion process. The search for promising materials in such a process requires the screening of a multitude of materials, as well as the development of an adequate evaluation metric. Several evaluation criteria have been introduced in the literature concentrating on a single adsorption or material property at a time. Parasitic energy is a new approach for material evaluation to address the energy load imposed on a power plant while applying CCS. Authors evaluate over 60 different materials with respect to their parasitic energy, including experimentally realized and hypothetical materials such as metal–organic frameworks (MOFs), zeolitic imidazolate frameworks (ZIFs), porous polymer networks (PPNs), and zeolites. The results are compared to other proposed evaluation criteria and performance differences are studied regarding the regeneration modes, (i.e. Pressure-Swing (PSA) and Temperature-Swing Adsorption (TSA)) as well as the flue gas composition.
