Experts appointed by the International Energy Agency analyze at CIC energiGUNE the development of technology for compact thermal energy storage

Scientist Stefania Doppiu, with the participation of the area of Energy storage (TES) of CIC energiGUNE, coordinates the tasks of the Work Group “Compact Thermal energy storage materials improvement”, within the framework of the IEA initiative that aspires to develop technologies of compact thermal energy storage to facilitate their access to the residential and industrial markets and to reduce their dependency on fossil energy.

CIC energiGUNE, the Basque research center of reference in battery storage, thermal energy solutions, and hydrogen, and member of the Basque Research & Technology Alliance-BRTA, hosts from the 27^th to the 29^th of October the meeting of the project “Compact Thermal Energy storage within Components within Systems”, sponsored by the International Energy Agency. “The celebration of this conference in Vitoria-Gasteiz is the verification that CIC energiGUNE has already positioned itself as an international referent agent in the field of thermal energy storage”, has expressed the scientific director of the TES area, Elena Palomo.

This initiative is led by Wim van Helden (AEE INTEC, Austria) and Andreas Hauer (ZAE Bayern, Germany) within the programs “Solar Heating and Cooling” (SHC) and “Energy Conservation through Energy Storage” (ECES), of the International Energy Agency (IEA). It is the world’s most important R&D network on Thermal Energy Storage, whose course started over more than 10 years ago and which the IEA renews now for the third consecutive time due to a great participation success and to the important scientific contribution that has been shown.

The project “Compact Thermal Energy Storage Materials within Components within Systems” centers on the development and characterization of new materials, and in the improvement of existing materials -including the study of possible degradation mechanisms and the improvement of their stability-, as well as aspects relative to their integration in components and systems of storage.

In this sense, its objective is to promote the development of compact and cheap thermal storage technology to accelerate its introduction into the market, hoping for its quick contribution to the decarbonization of heating/refrigeration and the production of hot sanitary water in the building sector, as well as to the heat processes in the industrial sector.

The people responsible for the project consider that a significant reduction of the fossil energy demand in both sectors can be reached using solar thermal energy and electric solar energy, and that the development of compact and cheap technologies of thermal energy storage can be the key to facilitating their implementation.
