Us solar thermal storage materials

What is thermal energy storage (TES) in solar energy field?

Usage of renewable and clean solar energy is expanding at a rapid pace. Applications of thermal energy storage (TES) facility in solar energy field enable dispatchability in generation of electricity and home space heating requirements. It helps mitigate the intermittence issue with an energy source like solar energy.

What are the properties of solar thermal energy storage materials?

2. The properties of solar thermal energy storage materials Applications like house space heating require low temperature TES below 50 °C, while applications like electrical power generation require high temperature TES systems above 175 °C .

What are the components of a solar thermal energy storage system?

The performances of solar thermal energy storage systems A TES system consists of three parts: storage medium, heat exchanger and storage tank. Storage medium can be sensible, latent heat or thermochemical storage material . The purpose of the heat exchanger is to supply or extract heat from the storage medium.

Which materials are used in thermal energy storage?

In high temperature side, inorganic materials like nitrate salts are the most used thermal energy storage materials, while on the lower and medium side organic materials like commercial paraffin are most used. Improving thermal conductivity of thermal energy storage materials is a major focus area.

What is a sensible heat thermal energy storage material?

Sensible heat thermal energy storage materials store heat energy in their specific heat capacity (Cp). The thermal energy stored by sensible heat can be expressed as Q = m ⋅ C p ⋅ Δ T, where m is the mass (kg), C p is the specific heat capacity (kJ kg −1 K −1) and Δ T is the raise in temperature during charging process.

Where can I find a specific thermal energy storage project?

To view specific thermal energy storage projects, search the Solar Energy Research Database. Learn more about CSP research, other solar energy research in SETO, and current and former funding programs.
