    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. This is why the...

    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...

    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...

    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. To ensure the employment of a shared methodology and the use of equivalent terms to...

    “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...
