This paper focuses on the experimental investigation of the transient thermo-mechanical behavior of a lab-scale prototype heat storage system. The experiment involves heating of the storage unit up to a set temperature of 70°C followed by a passive cooling, and monitoring the thermally induced strains and stresses in the sensible heat storage module. The results show a significant development of induced thermal strains and stresses in the heat storage unit upon heating, particularly at the interface between the embedded heating element and the soil.
