June 29 (Renewables Now) - German polysilicon producer Wacker Chemie AG (ETR:WCH) said today it will be supplying silicone fluid to Chinese solar thermal plant components maker Royal Tech CSP Ltd.

The Chinese firm will use Wacker’s newly developed HELISOL silicone fluid as a heat-transfer medium in its concentrated solar power (CSP) plants.

Wacker says that in combination with Royal Tech’s parabolic trough collectors, the HELISOL fluid, with “very high heat resistance and durability”, enables achieving efficiency levels that are not possible with conventional heat-transfer fluids.

“Our partnership with Royal Tech will contribute to significantly enhancing the efficiency of solar power plants and, in turn, bolster the market position of our two companies in the highly promising market for high-performance CSP systems," said Auguste Willems, member of Wacker's executive board.

Royal Tech is currently building a 50-MW CSP plant in the city of Yumen, Gansu, and has a 100-MW project in Inner Mongolia.
