IEA SHC Task 42: Position Paper
August 2015 - PDF 0.2MB
By: IEA SHC Task 42
This position paper explains the potential, the present status of development and the market status of compact thermal energy storages. Its aim is to inform policy makers, decision makers and opinion makers about the technologies and to discuss the technological and non-technological barriers and the actions needed to accelerate the development and market uptake of these very important technologies.

To reach high solar fractions, it is necessary to store heat or cold efficiently for longer periods of time. At this time, there are no cost-effective compact storage technologies available. For high solar fraction systems, hot water stores are expensive and require very large volumes of space. Alternative storage technologies, such as phase change materials (PCMs), sorption materials and thermochemical materials (TCMs) are only available at the laboratory scale, and more R&D is needed before they are available commercially.
