What is solar pond?

Solar pond is a reservoir of water with different salt concentration implements to gather and store the incident solar energy which it can be employed later on in different thermal energy applications, such as industrialized heating process, electricity power generation, farming crop drying and cooling of houses.

How do solar ponds work?

Solar ponds include several different concepts, but all use water to absorb solar energy and store energy in the heat form. Solar ponds contain layers with varying densities. The top layer absorbs solar energy, while the bottom layer stores thermal energy for use.

How does solar energy affect a pond?

If the water is relatively translucent, and the pond’s bottom has high optical absorption, then nearly all of the incident solar radiation (sunlight) will go into heating the bottom layer. When solar energy is absorbed in the water, its temperature increases, causing thermal expansion and reduced density.

Are solar ponds a viable source of energy?

Numerous technologies that can capture and store solar radiation have been developed because of the possibility of using solar energy to meet the bulk of human energy needs (Adediji et al., 2023; Adeyinka et al., 2023; Oladimeji, et al., 2020). Solar ponds have received attention as a viable means of storing heat (Saleh, 2022).

Are solar pond power plants suitable for remote areas?

Solar pond power generation can be suitable for remote areas with ample sunlight and a need for decentralized power generation. However, it has certain limitations. Solar pond power plants are typically small-scale and may not be suitable for large-scale power generation.

What is solar pond power generation?

Solar pond power generation involves utilizing the temperature difference between the hot bottom layers and the cooler surface layers of the solar pond to drive a heat engine or a thermodynamic cycle. This temperature difference is known as a “thermal gradient.”
