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 ( euros /m") and improving performance.

The Ultimate Trough will be optimized for large solar fields in the range of 500,000 to 2,500,000m" 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 4m" 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.

Critical Minerals Ignite Geopolitical Storm
Washington DC (SPX) Oct 12, 2011
The clean energy economy of the future hinges on a lot of things, chief among them the availability of the scores of rare earth minerals and other elements used to make everything from photovoltaic panels and cellphone displays to the permanent magnets in cutting edge new wind generators. And right out of the gate trouble is brewing over projected growth in demand for these minerals and th ... read more
