Swiss Symposium Thermal Energy Storage Unlocking the power of thermal energy storage for a sustainable future – Our Symposium serves as a dynamic platform for industrial partners, researchers and enthusiasts in the field to come together annually. This event fosters an exchange of cutting-edge technologies, groundbreaking research and innovative applications to the challenges and opportunities in thermal energy storage (TES).  The event combines different inputs from experts in politics, fundamental science, project implementation and pilot initiatives, along with an interactive workshop and a discussion panel. The symposium aims to unite the major figures in the field of TES, exploring important subjects and facilitating the initiation of valuable collaborations. By bringing together a global community of thinkers and doers, we explore how TES can impact sustainable and resilient energy systems in the future both in Switzerland and abroad.
