Compact Thermal Energy Storage

Task 42 - 2nd Experts Meeting

September 23-25, 2009

You are kindly invited to the 1st Workshop and Experts meeting of the Task 42 /Annex 24 (“4224”) “Compact Thermal Energy Storage – Material Development and System Integration”, which is a joint activity of the “Solar Heating and Cooling and the “Energy Conservation through Energy Storage” Implementing Agreement of the IEA.

For the performance of thermal energy storage systems their thermal energy and power density are crucial. Both criteria are strongly depending on the materials used in the systems. After a number of thermal energy storage technologies have reached the state of prototypes or demonstration systems a further improvement is necessary to bring theses systems into the market. The development of improved materials for TES systems is necessary to achieve this. The step to improved thermal energy storage materials requires the collaboration of a large number of materials experts in both fundamental and applied research, together with experts in the application of the materials in components and systems for thermal energy storage.

 In Addition to that the more precise knowledge from pilot and demonstration projects concerning the real boundary conditions of the TES systems is necessary to put up a profile of requirements for the material properties. In a lot of cases these conditions are quite different from the assumptions made in the beginning of the development.
