Novatec Solar’s Fresnel collector has successfully generated superheated steam at temperatures above 500°C at its 1.4 megawatt (MW) demonstration plant in Murcia, Spain, by implementing an innovative receiver design.
“With this technical achievement, Novatec Solar takes a leading position in the development of high temperature CSP technology”, says Martin Selig, Head of Market and Product Development. “It combines the low cost nature of our Fresnel technology with high cycle efficiency of superheated steam turbines, leading to significant reduction of electricity generation cost of concentrated solar power.”
The superheated steam technology uses vacuum absorber tubes being integrated in Novatec Solar´s market proven technology that is currently deployed in all commercial projects of Novatec Solar. “By using vacuum receivers, the heat losses can be reduced by 50 % compared to the Nova1 technology.” says Dr.-Ing. Max Mertins, Head of Research & Development.
The German Aerospace Center (DLR) has been engaged as an independent certifier to carry out performance tests on the superheated steam plant. DLR’s certification will provide a reliable basis for all future CSP projects that use superheated steam.
Novatec Solar is a leading provider of Linear Fresnel CSP technology, using flat mirrors to concentrate the sun’s energy onto a receiver to generate steam. The steam can be used to generate electricity, in new power stations or as a fuel saver in existing ones and also in other industrial applications requiring process heat including enhanced oil recovery and district cooling.
Novatec Solar’s 1.4MWe demonstration plant in Murcia, has been connected to the Spanish national electricity grid since March 2009. The company began constructing the world’s first commercial 30MWe Linear Fresnel power plant in April 2010, also in Spain, and is building a solar field to reduce emissions at a coal-fired power plant at Liddell in Australia.
Novatec Solar has developed a highly automated manufacturing process and solar field cleaning system. In March 2011, ABB, the leading power and automation technology group, acquired a 35 percent shareholding in Novatec Solar.
Novatec Solar was founded in 2006 by management shareholders Martin Selig, Dr. Max Mertins and Gerhard Hautmann. Novatec Solar is based in Karlsruhe, Germany. The Novatec management team is made up of experts from solar energy research and development, automotive mass production and power plant design. Novatec Solar’s focus is the production, development, implementation and operation of solar boilers based on Fresnel collector technology.
