Solar Thermal Power Is Unrestricted By Materials Availabilty

Solar Thermal Power Is Unrestricted By Materials Availabilty

Solar thermal power is, for the most part, unrestricted by materials availability, according to new research from the Chalmers University of Technology. There are still a few minor issues left, though, such as finding a replacement for the silver in mirrors. Parabolic trough collectors at the PSA, Plataforma Solar de Almeria, experimental facilities in Spain. Concentrated sunlight heats up a synthetic oil in the pipes at the focus of the troughs. With growing international export restrictions on rare earth metals, and diminishing availability, the dependency that some renewable technologies have on scarce materials has gained attention. Some of the main players in the wind and solar industries have been attempting to greatly limit their use of restricted elements, such as indium, or rare earth metals. There has also been a growing notion within the solar industry that Conc...
