As electrification accelerates, the role of thermal energy storage (TES) is more relevant than ever — especially when seen from the demand side. The 13th edition of the Swiss Symposium on Thermal Energy Storage will therefore focus on a demand-driven perspective: starting from real application needs and finding the most suitable TES options to meet them. From industrial processes to buildings and district energy systems, we’ll look at how different types of thermal storage can contribute to making energy systems more flexible, robust, and climate-friendly.
