Description
The goal of Annex 33 was to support an application-oriented development of innovative and compact thermal energy storage materials: Phase Change Materials (PCM) and Thermochemical Materials (TCM).
This included, first, the characterization of a new material concerning its properties like heat of fusion or heat of reaction, specific heat, thermal conductivity, and others. In a second step, the material has to be tested under reference application conditions. These conditions shall be identified for energy relevant applications in a separate approach. The third step focuses on the interaction between the storage material and the storage component, and mainly with the heat and mass transfer performed in the component or reactor. Thereby, first results towards a reliable power and energy density can be deduced.
