The 130MWh Electric Thermal Energy Storage (ETES) demonstration project, commissioned in Hamburg-Altenwerder, Germany, in June 2019, is the precursor of future energy storage solutions with gigawatt-scale charging and discharging capacities. Siemens Gamesa, Hamburg University of Technology, and Hamburg Energie.
Thermal energy storage (TES) is increasingly important due to the demand-supply challenge caused by the intermittency of renewable energy and waste heat dissipation to the environment. This paper discusses the fundamentals and novel applications of TES materials and identifies appropriate TES materials for particular applications.
Thermal energy storage (TES) systems store heat or cold for later use and are classified into sensible heat storage, latent heat storage, and thermochemical heat storage. Sensible heat storage systems raise the temperature of a material to store heat. Latent heat storage systems use PCMs to store heat through melting or solidifying.
The optimal strategy for integrating TES with buildings has yet to be determined for various applications of TES. Nevertheless, thermal storage materials are far less costly per unit of energy stored than electricity storage materials.
As TES can also provide heat, this technology could also be used in this sector. Therefore, as this technology is capable of providing additional services to the energy system, it is likely that including the heat sector in future studies would increase the benefits from and potential of thermal storage. Static demand.

TES can help improve system performance by smoothing supply and demand and system temperature fluctuations, as well as imp ving the reliability of the heating and / or cooling source.Thermal energy storage technologies can be divided into three
