High-temperature technologies can be used for short- or long-term storage, similar to low-temperature technologies, and they can also be categorised as sensible, latent and thermochemical storage of heat and cooling (Table 6.4).
This approach addresses the planning and operation of the energy system ''as a whole'', across multiple energy carriers, infrastructures, and consumption sectors. It sets out several actions to implement the necessary reforms, including the promotion of energy storage technologies for sector coupling.
Among others, depleted hydrocarbon-bearing reservoir formations may constitute favorable storage conditions for HT-ATES. This study characterizes these reservoirs in the Upper Rhine Graben (URG) and quantifies their heat storage potential numerically.
Thermal energy storage in oil and gas reservoirs leverages the existing surface and subsurface infrastructure, which can pave the way for economic production of geothermal energy.
For sensible storage, the reduction of thermal oil by low-cost filler materials and their compatibility is investigated at elevated temperature. It can be concluded that the materials are compatible up to 320 °C.
Traditionally, CSP plants have used synthetic oils as heat transfer fluids and molten salts for thermal energy storage. At the National Renewable Energy Laboratory (NREL), we are improving these materials as well as developing and characterizing advanced nanofluids and phase-change materials (PCMs) for thermal storage applications.
Geothermal energy technologies allow for energy production as well as storage. Already today, numerous storage applications exist, especially in shallow underground systems
This paper reviews past experiences from moderate and high-temperature reservoir thermal energy storage (RTES) projects, along with hot water and steam flood enhanced oil recovery (EOR) operations, to identify technical challenges encountered and evaluate possible ways to address them.
We start with a discussion of existing high temperature energy storage technologies and a brief market analysis, and follow with a discussion of the challenges with high temperature EES devices including material limitations, as well as thermal degradation mechanisms.
For sensible storage, the reduction of thermal oil by low-cost filler materials and their compatibility is investigated at elevated temperature. It can be concluded that the materials are compatible up to 320 °C.
High-temperature thermal storage (HTTS), particularly when integrated with steam-driven power plants, offers a solution to balance temporal mismatches between the energy supply and demand.

The main technological innovation of the company relies on the developed high temperature storage material in the form of purposely produced pellets or bricks, with high heat capacity and thermal conductivity.
In the heating sector, characterized by demand seasonality of the residential demand, or batch processes of the industrial demand, the thermal storage with proper duration is a key technology to decouple energy supply and demand, and accommodate their temporal mismatches.
High-temperature storage offers similar benefits to low-temperature storage (e.g. providing flexibility and lowering costs). However, high-temperature storage is especially useful for smart electrification of heating and cooling in industry, given that many industrial processes either require high temperatures or produce high-temperature heat.
This review summarizes the major developments, limitations, and opportunities in the field of high temperature electrical energy storage (EES) devices, with an emphasis on Li-ion batteries and supercapacitors.
