Thermal energy storage (TES) is the storage of for later reuse. Employing widely different technologies, it allows surplus thermal energy to be stored for hours, days, or months. Scale both of storage and use vary from small to large – from individual processes to district, town, or region. Usage examples are the balancing of energy demand between daytime and nighttim. So Q = M * Cp * (T1 - T2) where Q is energy, M is mass, Cp is specific heat capacity and T are the temperatures. [pdf]

The different kinds of thermal energy storage can be divided into three separate categories: sensible heat, latent heat, and thermo-chemical heat storage. Each of these has different advantages and disadvantages that determine their applications. Sensible heat storage (SHS) is the most straightforward method. It simply means the temperature of some medium is either increased or decreased. This type of storage is the most commerciall. Thermal energy storage can: Reduce peak demand and level demand by storing energy when there is less demand and releasing when there is high demand. Reduce CO2 emissions and costs by making sure energy is used when it is cheaper and there is more renewable energy in the mix. Increase the overall energy efficiency of energy systems. [pdf]
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.
The energy, in the form of hot or chilled water, can then be distributed to buildings via a pipe network for immediate use or be stored in thermal storages for later use. The thermal energy can be stored for a few hours or days, for example in heat storage tanks, or for several months in large pits or other storage facilities.
Each outlook identifies technology-, industry- and policy-related challenges and assesses the potential breakthroughs needed to accelerate the uptake. Thermal energy storage (TES) can help to integrate high shares of renewable energy in power generation, industry and buildings.
Solar thermal energy or waste heat from several processes can be used to regenerate the adsorbent and promote energy storage . The adsorption cycle has already been used in several research projects to promote TES.
Heat storage, both seasonal and short term, is considered an important means for cheaply balancing high shares of variable renewable electricity production and integration of electricity and heating sectors in energy systems almost or completely fed by renewable energy.
Other sources of thermal energy for storage include heat or cold produced with heat pumps from off-peak, lower cost electric power, a practice called peak shaving; heat from combined heat and power (CHP) power plants; heat produced by renewable electrical energy that exceeds grid demand and waste heat from industrial processes.

The DOE energy storage valuation tools are valuable for industry, regulators, and other stakeholders to model, optimize, and evaluate different ESSs in a variety of use cases. There are numerous similarities and differences among these tools.
Valuing energy storage is often a complex endeavor that must consider different polices, market structures, incentives, and value streams, which can vary significantly across locations. In addition, the economic benefits of an ESS highly depend on its operational characteristics and physical capabilities.
As indicated in Section 2.1, the daily accumulated heat volume is the necessary capacity of the thermal energy storage that would guarantee the continuous operation of the CHP plant throughout the 365 days of the year .
Battery Energy Storage Evaluation Tool (BSET): BSET is a modeling and analysis tool enabling users to evaluate and size a BESS for grid applications. It models the technical characteristics and physical capability of a BESS. It also incorporates operational uncertainty into system valuation.
Taking advantages of the knowledge established in the academic literature and the expertise from the field, there are efforts from multiple parties (e.g., national laboratories, utilities, and system integrators) in developing software tools that can be used for valuing energy storage.
