Thermal energy storage is a proven method to improve flexibility of energy supply systems and to reduce energy consumption. In particular, storage systems based on sorption processes offer very high energy storage densities and accomplish thermal energy storage for unlimited periods, as long as sorbent and sorbate can be stored separately.

We have a versatile experimental setup to evaluate adsorption thermal energy storage units at various process conditions, e.g. with charging temperatures up to 250°C.


To develop efficient storage units, we use dynamical simulations with validated models of adsorption thermal energy storage units. We analyze the integration of those storage units in energy systems and quantify the advantages of thermal storage for industrial, residential and mobile applications.
