Solar fish pond filtration power generation system

Are salt gradient solar pond hybrid systems effective?

With the integration of salt gradient solar pond hybrid systems, a maximum lower convective zone (LCZ) temperature of 90 °C, more than 50 % energy/exergy efficiency, and power generation of up to 5 MW are reported in this review.

What is a solar pond?

Solar ponds are low-grade thermal energy systems that can also be used to absorb/store solar radiation. Extensive research/advances in solar pond performance have been sparked by the potential influence of various types of heat storage systems with heat extraction mechanisms.

How efficient is a solar pond?

For instance, an autonomous desalination unit exhibited about 54 % exergy efficiency and a production of about 2381 m3 (annually 73.3 %) of potable water. Countries that are currently deploying/considering solar pond systems. Working illustration of solar ponds with salinity and temperature gradients . Timeline of solar pond developments.

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.”

Can salinity gradient solar ponds generate electricity?

Their result showed that heat extraction from the gradient layer can increase the energy efficiency of the pond for electricity generation. Hence, salinity gradient solar ponds have demonstrated great potential for electricity generation, with several advantages over other renewable energy technologies.

How solar energy is used in fish ponds in Indonesia?

Based on the geographical region, fish pond located away from power lines. So, it is necessary to use local potentials of renewable energy such as solar energy. The annual average solar radiation in Indonesia is 4.5 kWh/m2/day with 9% monthly variation.
