Abstract
The theory of sorption processes and its relevance for thermal energy storage (TES) concepts shall be introduced. Starting from the thermodynamics of TES systems a motivation for sorption storage systems will be developed. The adsorption theory is based on the adsorption equilibrium. The equilibrium can be described by isotherms (curves of equal temperature), isobars (curves of equal water vapour pressure) and isosteres (curves of equal water concentration within the adsorbent). From the adsorption equilibrium the adsorption enthalpy or heat of adsorption can be calculated. The heat of adsorption describes the amount of energy involved in the process. The ratio of discharged to charged thermal energy and the possible storage capacity of different applications derived from the adsorption equilibrium and the heat of adsorption will be defined. A similar method—from the equilibrium to the storage capacity—will be shown for liquid sorbents.
