Supernova is designed for direct steam generation with a temperature of 450°C. Fresnel technology uses water instead of thermo oil as a heat transfer medium.

SCHOTT Solar says its evacuated receivers are qualified for the high temperature area of these CSP power plants in particular due to a new coating of the absorber tube. The coating was developed in collaboration with the Fraunhofer ISE Institute and shows heat losses of less than 10% at a working temperature of 400°C.

"As a supplier of the receiver, the key component of parabolic trough power plants, SCHOTT Solar is pleased to now also deliver receivers for CSP plants with Fresnel technology.” says Christoph Fark, Managing Director of SCHOTT Solar CSP GmbH.

“Using evacuated receiver tubes will further increase the efficiency of fresnel power plants and once more accentuates SCHOTT Solar’s technology leadership."

SCHOTT Solar will supply receivers to be used in tests at Novatec’s PE1 CSP plant this autumn.
