Fig. 2. Materials performance for a TVSA carbon-capture process at 0.6 bar added to a cement plant in the UK.

a, The nCAC versus recovery, with colour coding the specific electrical energy consumption. b, The nCAC versus purity, with colour coding the specific thermal energy consumption. c, Specific thermal energy consumption for heating versus productivity, with colour coding the recovery. d, MR:MM versus climate change, with colour coding the nCAC. Sbe, antimony equivalent. Our visualization tool²⁵ gives an interactive version of this graph. The dotted lines in a, c and d show the MEA benchmark (Supplementary Information Section 4). In b, the vertical orange dotted line gives the purity required for geological storage (>96%) and in a, the blue shaded area gives the uncertainty. Each dot represents the corresponding KPI of a material.
