An objective for material design for a TSA process is to minimize the total heat required to regenerate the material per kilogram of recovered CO 2 . In Figure , we show this heat requirement for a set of MOFs in a TSA process, for which, we compare the heat requirement using the actual values of the heat capacity with the assumption of a constant heat capacity (0.985 J.g -1 .K -1 ). For the materials with a heat capacity close to the reference value (green dots), the heat requirement does not change, and hence, we do not need a correction.
