By the use of sand, the concentrated solar power will be coerced to contend with the traditional photovoltaic method.
Entitled “Sandstock”, the research which was printed during the Solar Power and Chemical Energy Systems Conference in South Africa, explains how sand can endure temperatures of up to 1,000°C.
Concentrated solar power, or CSP, will have to use solar panels or mirrors to reflect heat from the sun to one area where the heat collected is stored and eventually converted into electricity.
According to the research, the higher you can drive the temperature, the more efficient the plant will be in producing electricity. CSP is considerably more efficient than photovoltaics at accumulating energy after sunset, and the Masdar researchers are testing out sand’s ability to store energy.
The maximum temperature for conventional CSP systems is marked at 600°C as molten salt, the main material, begins to break down beyond that point. On the other hand, sand can store it at 400°C higher compare to molten salts.
In order to make CSP more viable, the outlay must be reduced.
