To mitigate the global warming, R&D is being directed towards understanding the relevant phenomena and foster innovation in the field of CO2 capture and sequestration (CCS). Knowledge about the CO2 sorption properties (adsorption capacity, pressure regimes, energetics and kinetics) is essential to design of advanced materials capable of capturing CO2 in industrial settings. Many materials including solids such as metal organic frameworks (MOFs) and liquids (ionic liquids) are considered as prospective candidates for CCS applications. The ability to assess energetics of carbon dioxide adsorption in addition to CO2 capacity is key to the successful application of the proposed systems such ionic liquids and MOFs. In this paper we demonstrate how calorimetric data in conjunction with adsorption data render insights into and assist in the further materials development. The adsorption data for MOFs and ionic liquids have been obtained using a Sievert’s apparatus. A critical analysis of volumetric technique and CO2 data  is presented. The paper also discusses the calorimetric results for MOFs and ionic liquids which have been obtained in-situ with a coupled system.
