Thermal storage for flexible sector integration
In his keynote speech at Eurosun 2020, Dr Andreas Hauer talked about the different roles that heat storage could play as part of a whole systems approach to energy policy. Thermal energy storage, or TES, can reduce energy consumers’ dependence on volatile heat sources and align heat with power demand in multiple ways. Hauer, who works at the Bavarian Centre for Applied Energy Research – ZAE Bayern, and Dr Wim van Helden, of AEE INTEC, Austria, co-chaired IEA SHC research platform Material and Component Development for Thermal Energy Storage from January 2017 to December 2019.

Round robins improve TCM testing
Thermochemical storage materials (TCMs) offer much higher storage capacities by mass or volume than sensible or latent heat storage and can store heat for an infinite amount of time almost without losses.

Compact heat battery with virtually no heat loss
A compact thermochemical seasonal storage system put up at a demonstration site in Warsaw, Poland, is working as expected. The prototype, developed and tested as part of an EU research project called CREATE, consists of three evacuated modules filled with 400 litres of salt each to store heat with no heat loss by hydrating the material (see the photo on the left).

Compact thermal energy storage: research in cycles
Research into compact thermal energy storage is made difficult by the fact that the performance of storage materials depends significantly on their intended purpose. For example, storage tanks that are integrated into space heating systems are made of materials different from those used to make tanks for process heat loops generating steam.

In search of cost-effective, advanced PCMs
Salt hydrates are the most interesting phase change material in the low-temperature range of up to 150 °C. Their volume-related enthalpy at melting is much higher than the enthalpy of paraffins and sugar alcohols (see the chart above) and they are comparatively inexpensive.

IEA SHC Solar Academy: Material and Component Development for Thermal Energy Storage - November 27, 2019
The International Solar Energy Society is hosting the next webinar in the IEA SHC Solar Academy's 2019 webinar series on Task 58 - Material and Component Development for Thermal Energy Storage. The IEA SHC Task 58 focuses on advanced materials for latent and chemical thermal energy storage, Phase Change (PCM) and Thermo Chemical (TCM) materials.

Encouraging faster materials development for compact storage
Research and industry experts in thermochemical storage materials are invited to participate in a workshop that will take place on 11 and 12 November in Erlangen, Germany. The objective of the event will be to outline a road map to a Thermal Energy Storage Materials Acceleration Platform (TESMAP).

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.

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.

IEA SHC Task 58: “We will need new and innovate designs for heat and mass exchangers”
Thermochemical materials (TCMs) used in storage tanks show higher heat capacities than water and smaller losses over time. They are crucial to an increase in solar use among consumers and the storage of summer heat for the winter season. However, they are also more complex than their water-based counterparts, which require only heat exchangers.
