General Coordination: Esther Rojas, CIEMAT, Spain
Promoting collaboration on Thermal Energy Storage (TES) to improve its reliability, integration on CSP plants and to develop a common language.
Results of the launched round robin tests:
- The normalized methods ASTM E1269 and MDSCTM are adequate for the measurement of the heat capacity of solar salt in the range of temperatures 200 and 400ºC. Paper: Round Robin Test on the Measurement of the Specific Heat of Solar Salt
- The procedure for measuring the reaction enthalpy should be improved in order to avoid any enthalpy source other than redox reactions while ensuring high oxidation rates. Paper: Round Robin Test on Enthalpies of Redox Materials for Thermochemical Heat Storage
Characterization of specific equipment for commercial TES
Coordinator: M. Rodriguez, CIEMAT, Spain
Problems and proposed tests under discussion.
Coordinator: P. Garcia, CEA, France
Existing related documents analyzed -> proposal to limit the scope of the activity to thermocline storage and latent heat storage. Key features under discussion.

- 23-24th June 2015: Workshop at CIEMAT premises.
Last June, CIEMAT hosted the first workshop of the just born TES working group where the activity lines and corresponding responsible people were defined.
Attendees to the Workshop on behalf of their corresponding centers and companies (SUPSI, DLR, Weizmann Institute, Tecnalia, CEA-LITEN, IMDEA Energía, University of Évora, CENER, ENEA, Abeinsa BD, Abengoa Research, SENER and CIEMAT).
