Market sector: Heat Storage

New chair for IEA SHC Programme on growth path

The new Chair of the IEA Solar Heating and Cooling Programme, also known as IEA SHC, is Tomas Olejniczak, an all-around energy transition and renewable energy expert at the Netherlands […]

Global thermal storage capacity to triple by 2030

There is a broad consensus that solar thermal storage has the potential to be an important driver of decarbonising energy systems around the world. Thermal energy storage, or TES for […]

Improved design for giga-size pit heat storage

Denmark’s cost-effective, tried-and-true seasonal pit heat storage concept needs to be modified if it is to be implemented across Europe, since district heat temperatures are higher and groundwater may be […]

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. […]

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 […]

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 […]

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 […]

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 […]
