Another most advantage solar thermal product range of Greenland Systems is “CONCENTRATE SOLAR COLLECTORS”
In order to provide the high temperature thermal energy to most industrial and manufacture requirement, Concentrate solar collector is must and most necessary.
We normal regard that the application temperature between 110° to 200° as medium range, 200° to 390° as medium to high.
However we combine the towel and trough concentrate together, it can reach to 1,000° which can be used for thermal hydrogen generate procedure. please have a look of following image
Concentrated solar thermal (CST) is a solar energy technology that uses sunlight to generate heat.
According to statistic number that 80% of Australian natural gas and LPG are used for industrial and primary industries process thermal demand. These thermal energy requirement range is about 90 to 200 degrees.
How does concentrated solar thermal work?
CST systems use mirrors (Trough or heliostats) to concentrate a large area of sunlight into a targeted location, producing high temperatures. This heat is captured using a fluid, such as oil or molten sodium, which can then be used to heat water to create steam to power a turbine and produce electricity (also referred to as concentrated solar power or CSP). The heat can also be used directly to decarbonise some industrial processes.

At the present, Hydrogen is produced now by combustion of natural gas, to chemically pull hydrogen out of a hydrocarbon at a temperature of 800°C to 900°C. Both steps create carbon dioxide emissions.
But in solar thermal (heat) energy, thousands of “suns” can be concentrated by mirrors and focused into a solar reactor to produce temperatures up to 1,500°C. There are no carbon emissions when hydrogen is made by a thermochemical reaction splitting water using the heat of a solar reactor.
When hydrogen is made with solar energy instead of natural gas, the feedstock is water, not a fossil fuel. Solar heat at about 800 C makes the water (H2O) split into hydrogen (H2) and oxygen (O).
Above the University solar thermal Hydrogen experiment platform, Total sun receipt area is 100 square meter. Towel focus temperature is 1,000 degree. By concentrate solar thermal energy approach to produce Hydrogen is most promise technology for the future.
