Top: (a, b) The equilibrium adsorption isobars are first experimentally assessed for two different samples with different adsorption capacity at 12.3mbar (symbols) and then theoretically extrapolated by using a Dubinin–Astakhov model (lines). Middle: Ideal adsorption cycles are reported for hypothetical seasonal thermal energy storage applications with maximum charging temperature of (c) \(T_p=80 \, ^{\circ }\hbox {C}\) and (d) \(T_p=140 \, ^{\circ }\hbox {C}\), respectively. Computations are here referred to the sample with the lowest adsorption capacity. Bottom: Ideal adsorption cycles are reported for hypothetical seasonal thermal energy storage applications with maximum charging temperature of (e) \(T_p=80 \, ^{\circ }\hbox {C}\) and (f) \(T_p=140 \, ^{\circ }\hbox {C}\) respectively. Computations are here referred to the sample with the largest adsorption capacity.
