High temperature solar thermal energy storage power generation

How are high temperature storage concepts classified in solar power plants?

Classification High temperature storage concepts in solar power plants can be classified as active or passive systems (Fig. 2). Fig. 2. Scheme of classification of different storage systems according the storage concept. An active storage system is mainly characterized by forced convection heat transfer into the storage material.

What is concentrated solar thermal power generation?

Concentrated solar thermal power generation is becoming a very attractive renewable energy production system among all the different renewable options, as it has have a better potential for dispatchability. This dispatchability is inevitably linked with an efficient and cost-effective thermal storage system.

What is high temperature thermal energy storage?

Of all components, thermal storage is a key component. However, it is also one of the less developed. Only a few plants in the world have tested high temperature thermal energy storage systems. In this context, high temperature is considered when storage is performed between 120 and 600 °C.

Why is thermochemical storage important in solar power generation?

Thermochemical storage (TCS) is very attractive for high-temperature heat storage in the solar power generation because of its high energy density and negligible heat loss. To further understand and develop TCS systems, comprehensive analyses and studies are very necessary.

Why is solar thermal power generation important?

Solar thermal power generation technology has great significance to alleviate global energy shortage and improve the environment. Solar energy must be stored to provide a continuous supply because of the intermittent and instability nature of solar energy.

What are the components of a thermal energy storage system?

Mainly, four elements are required in these plants: concentrator, receiver, transport/storage media system, and power conversion device. Of all components, thermal storage is a key component. However, it is also one of the less developed. Only a few plants in the world have tested high temperature thermal energy storage systems.
