Abstract
Thermal energy storage technologies occupy a unique position in the energy sector. On the one hand, the basic principles of storing heat have been understood for well over a century and applied in domestic and industrial settings. This includes concepts as fundamentalas hot water heaters or regenerator heat storages in steelmaking processes. These technologies are well-established within their respective sectors and have contributed to the efficient and convenient use of heat in many ways.On the other hand, there are novel applicationsof thermal storage that are beginning to be exploited and new technologies that are being applied in innovative ways. The story begins with classical technologies that are currently finding new uses in power plants, district heating grids and industrial processesin order to provide a wide range of benefits. These include energy efficiency in processes, increased use of renewable energy and cost savings. In addition to this, there have been technological developments that are opening new doors within well-known applications. Some suitable examples are the cost-effective storage of molten salts in a thermocline, high-temperature latent heat storage for high power levels and thermochemical reactions that can store heatloss-free.
