Can solar receivers and thermal energy storage be combined?

Integrating solar receivers and thermal energy storage in a concentrating solar thermal plant helps to enhance plant efficiency and cost-effectiveness. Here, we provide an overview of the technology to unify solar receivers and thermal energy storage into a single system.

What is a thermal energy storage system?

A second solution is to use a thermal energy storage (TES) system to store heat during sunshine periods and release it during the periods of weak or no solar irradiation (Figure 1). Figure 1. CSP plant with a TES system The development of an efficient and cost-effective TES system is crucial for the future of CSP technologies .

How does thermal energy storage improve the economic feasibility of CSP plants?

As known, electricity production in conventional CSP plants is concentrated during the daily period with solar energy availability. The integration of a thermal energy storage system which makes the electricity production more flexible improves the economic feasibility of CSP plants.

What is a two tank thermal energy storage system?

Active two-tank systems The principal elements for a two-tank thermal energy storage system are the material inventory, HTF, heat exchangers and the storage tanks, apart from the storage material circulation pumps. During charging, the amount of heat stored in the fluid depends on the heat supplied by the solar field.

Why is thermal energy storage important?

Solar energy increases its popularity in many fields, from buildings, food productions to power plants and other industries, due to the clean and renewable properties. To eliminate its intermittence feature, thermal energy storage is vital for efficient and stable operation of solar energy utilization systems.

What is the difference between concentrating solar power (CSP) and thermal energy storage?

In contrast, concentrating solar power (CSP) plants which supplies thermal energy to the power cycle, obtain yields close to 100% through their combination with thermal energy storage (TES) systems [3, 4]. Furthermore, the capital cost of TES is lower than mechanical or chemical storage systems .
