DecaTES: Decarbonization strategies integrating thermal energy storage [PID2021-123511OB-C31]

Call: PID2021

To achieve deep decarbonization, renewable energies must become dominant in the energy system. To match demand and supply in these systems, energy storage solutions are a main bottleneck, especially for medium- and long-term storage. Besides other technologies (batteries, pumped storage, H2, etc..) thermal energy storage (TES) should be included in the analysis. It has a potential for low cost at GW scale and can have a significant contribution to decarbonization both in short, medium- and long-term storage and at different temperature levels. Previous projects of the universities participating in this proposal focused on the improvement of materials, their characterization, the development of new materials, the design and the evaluation of different applications for TES systems, barriers to their implementation, and circular economy. A new challenge is presented by the decarbonization strategies at European and national level. There are many pathways to decarbonization, but not all are cost-effective and consider critical materials. In actual strategies, the potential of TES is not yet properly considered. Therefore, the main objective of DecaTES is to develop and validate a methodology to assess the contribution of thermal energy storage in the decarbonization strategies in industry and built environment. We propose to apply this methodology to different case studies in industry and built environment at component, system and regional level.
