Steady-state Model for Closed-Sorption Thermochemical Heat Storage Systems

In the field of energy storage, the classification and evaluation of thermochemical storage systems

pose significant challenges. Unlike for traditional thermal storage systems, capacity, power, and other

key performance indicators (KPIs) cannot be described easily, because they strongly depend on

diverse and interdependent boundary conditions. The lack of a straightforward methodology for

assessing these systems hinders the understanding of their application potentials and hence its

deployment. This paper introduces a modeling approach aimed at simplifying the assessment of

absorption based thermo-chemical storage systems, particularly assessing the thermodynamic steady-

state conditions.
