October, 11th 2011 (Nuernberg/ Stuttgart, Germany) – FLABEG and schlaich bergermann und partner, both specialized in the CSP business, will be working together to make CSP technology more competitive. Since January 2010 a high level engineering team comprised of both companies is developing a brand new collector – the Ultimate Trough®. This innovative collector design has been further supported by DLR (German Aerospace Center) and the FhG IML (Fraunhofer Society, Institute for material flow and logistics), and will be about 25 percent more cost effective compared to the current standard parabolic trough, the Eurotrough, by lowering specific cost (€/m²) and improving performance.

The Ultimate Trough® will be optimized for large solar fields in the range of 500,000 to 2,500,000m² aperture area. A larger diameter of the heat collection elements, supported by improved selective coatings with lower emissivity, allows a solar field design with lower specific parasitic consumption and less piping in the solar field. Also the number of drives, sensors and controls is reduced by more than 50 percent. In addition the number of units to be assembled, checked, mounted, aligned and commissioned will be reduced by larger solar collector elements. The highly efficient solar mirrors with a new dimension of 4m² will guarantee a superior and unprecedented performance.

“With this new collector development FLABEG makes CSP technology more competitive” says Paul Nava, Manager Business Development. He and his engineering team extend FLABEG’s scope to engineering services and project development support in the realm of parabolic trough technology. Currently a Prototype, consisting of two collector elements, is being tested in preparation for a demonstration loop in the US where two SCAs (Solar Collector Assembly) will be running in the SEGS VIII plant during spring of the next year to validate the significant performance improvements.

As the pioneer of solar technology with a worldwide network, FLABEG produces mirrors for all CSP –technologies – Parabolic Trough, Dishes, Tower and Linear Fresnel, and CPV applications. Due to latest coating technologies, FLABEG solar mirrors are characterized by a reflectivity of more than 95%. The extremely robust mirrors have been installed in the first commercially operated power stations since the 1980s and are in daily operation now for more than 25 years without any loss of performance.

schlaich bergermann und partner mainly operates in the specialized field of structural engineering covering long span bridges as well as light weight roof structures and delicate glass facades. For more than 25 years their engineers have been focusing on the commercial use of solar energy and are designing and building solar solar power plants and collector fields.
