Societal and industrial impact

Thermal Energy Storage (TES) helps make energy systems more flexible, efficient and sustainable by storing heat or cold when it is available and using it when needed. As energy systems become increasingly electrified and reliant on renewable energy sources, TES is emerging as a key enabling technology for the energy transition. 

Past editions of the TES Workshop

2022: The first TES Workshop organised under GS TES (previously hosted by SINTEF Energy Research) was held as a hybrid event, gathering 20 participants onsite and over 50 online. It marked the beginning of the Centre's efforts to engage both local and international TES communities.

2023: The workshop attracted more than 50 participants onsite and 50+ online. For the first time, international speakers were invited to present in Trondheim, expanding the event's global reach.

2024: Continuing its growth, the workshop maintained a similar attendance with 50+ participants onsite and online. The program featured a diverse lineup of international speakers and increased industry involvement.

This workshop not only serves as a knowledge-sharing platform but also plays a vital role in shaping the strategic direction of TES research and implementation in Norway and beyond.
