Thermal energy storage ( TES) is the storage of thermal energy 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.
A Carnot battery first uses thermal energy storage to store electrical energy. And then, during charging of this battery electrical energy is converted into heat and then it is stored as heat. Now, upon
Initial Conclusions from EPRI''s Analysis. TES effective round-trip efficiency can be high as the thermal energy was never converted to power before discharge. Capital cost is on the order of $100/kWh, i.e., 3 to 4 times less than Li-ion batteries today. TES systems do not degrade with cycling – longer plant life.

Geothermal power plants can run off temperatures ranging from just 250° to 700°F; heat can be used directly from temperatures ranging from 100° to 300°F for space heating, industrial, and agricultural uses; and the consistent 50° – 60°F found only 10 feet underground can heat and cool buildings and communities of all sizes.
Thermal energy storage at temperatures in the range of 100 °C-250 °C is considered as medium temperature heat storage. At these temperatures, water exists as steam in atmospheric pressure and has vapor pressure. Typical applications in this temperature range are drying, steaming, boiling, sterilizing, cooking etc.
