Marcelina Grabowska (bibliometric data).Executive SummaryThermal energy storage (TES) technologies balance the thermal energy demand and supply. TES enables the storage of excess energy during periods of abundant supply and subsequently use it during periods of supply scarcity. Likewise, it achieves cost savings as inexpensive energy
with renewable heating technologies requiring heat storage. As space comes as a premium in most UK cities, the integration of thermal stores into energy centres of large buildings is often a key constraint for TES. For district heating applications that were built without significant thermal storage, finding an
it can be used as waste heat in district heating networks.However, Thermal Energy Storage technologies are the key to matching thermal energy grids with power grids. Excess electricity could be stored in the form of heat by using solid media solutions or Compressed Air Energy Storage technolog
