11th Swiss Symposium Thermal Energy Storage, 26th January 2026

10th Swiss Symposium Thermal Energy Storage 2023 - How far have we come? What is still to be done?

The Swiss Symposium Thermal Energy Storage celebrated its 10th anniversary. We took this opportunity to reflect on the past decade, review what we have achieved so far and make joint decisions on what we will focus on in the next decisive years. The festival format of our symposium had a highly interactive and networking character with lectures, workshops and an exhibition. Key industrial and academic players in the field of thermal energy storage have come together. It was a great opportunity to identify key topics and start new collaborations.

Exhibition

SSTES Exhibition

This year we offered companies the opportunity to have a stand, which was visited during all breaks and was also well attended during the closing apero. The exhibitors all brought an object that could be touched and experienced.

Thank you very much to this year's exhibitors:
