Thermal energy storage, in which energy is stored as heat in materials such as water, oils, or molten salts, offers a promising alternative. The heat can be collected directly from the sun by concentrating sunlight, or by converting extra wind or solar power using heat pumps. When needed, the heat is released to drive a generator that produces

Coupling solar energy and storage technologies is one such case. The reason: Solar energy is not always produced at the time energy is needed most. or other material is used to store heat. This thermal storage material is then stored in an insulated tank until the energy is needed. The energy may be used directly for heating and cooling, or
There is also an option to store solar energy in the form of heat, which is the main form of storage in concentrated solar power plants, where the heat transfer fluid passes through the receiver (where all the heat is concentrated), absorbs thermal energy and then stores it in hot thermal tanks that are available for usage when the electricity is needed.
