Abstorex – Seasonal thermal storage system for solar energy
A 1 kW closed sorption thermal energy storage system (TES) prototype is set-up and tested at HSR-SPF. This can be charged in summer with heat from solar thermal collectors or with electricity from photovoltaic modules. The system can achieve a significantly higher volumetric energy density compared to sensible hot water storage. The closed sorption system is designed to work with different sorbent-sorbate pairs (NaOH-H₂O, LiBr-H₂O and LiCl-H₂O). Scaling to larger units with correspondingly higher power will be done in the frame of SCCER HaE (Heat and Electricity).
