Material & Components for Thermal Energy Storage

Material and Component Development for Thermal Energy Storage

This joint SHC Task 58 / ECES Annex 33 deals with advanced materials for latent and chemical thermal energy storage, Phase Change (PCM) and Thermo Chemical (TCM) materials. The task deals with these materials on three different scales:

  • Material  properties, focused on their behaviour from molecular to bulk scale, including material synthesis, micro-scale mass transport and sorption reactions;
  • Material performance within the storage system , focused on the materials behaviour and when they are implemented in the storage itself, including heat, mass, and vapour transport, wall-wall and wall-material interactions, and reactor design;
  • Storage system implementation, focused on the performance of a storage within a heating or cooling system, including for instance economical feasibility studies, case studies, and system tests.

Because seasonal storage of solar heat for solar assisted heating of buildings is the main focus of the IEA-SHC TCP, this will be one of the primary focus areas of this task. However, because there are many more relevant applications for TES, and because materials research is not and cannot be limited to one application only, this task will include multiple application areas.

What's New
  • Solar Award Nominations are Open - The Solar Heating and Cooling Award of the IEA SHC Programme celebrates the success of those working to increase the market impact of this renewable energy source. (Posted: 2019-02-15)
  • Online database on advanced PCMs - Compared to water, phase change materials (PCMs) offer more capacity to store heat in tanks. As a consequence, researchers in all corners of the world have been developing new materials and their properties. (Posted: 2018-10-23)
  • Excellent material for sorption-based solar energy storage - Microporous hydrophilic substances such as zeolites are recognised as promising materials for very efficient energy storage. Solar thermal systems are used to dry the material and store all of the thermal energy inside without losses until water is returned into the structure to release sensible heat. (Posted: 2018-10-10)
