Parabolic trough plants - top solar thermal technology
At present, parabolic trough power plants are the most efficient and economical technology available to generate electricity from solar energy. This technology has been employed in large-scale installations for more than 20 years. A parabolic trough power plant produces environmentally friendly solar electricity withn a range of 30 to more than 250 megawatts. This will supply between 100,000 and 1,000,000 people with electrical energy in a safe, reliable and clean manner.
A parabolic trough power plant consists basically of a solar field and a conventional power block. Parabolic trough-shaped mirrors in the solar field concentrate the incident solar radiation onto an absorber tube located in the focus line of the collector. A heat transfer fluid inside the absorber tube is heated by the absorbed solar radiation and produces steam in the power block by means of heat exchangers. From there, the steam is fed into a turbine to generate electricity in the same way it is done in conventional power plants. With an integrated thermal energy storage system, the supply of electricity can be stored and made available in a plannable manner..
State-of-the-art solar thermal technology due to the Andasol-ET collector
The key component of every solar field is the parabolic trough collector. The design of the optimized EuroTrough collector, also known as the Andasol-ET collector, has proved to be economical, precise and highly efficient .The Andasol-ET collector was developed under the leadership of our partners and represents the consistent refinement and improvement of preceding collector ranges. The decrease of the costs and the simultaneous improvement of the technical performance, resulting in a significantly higher degree of effectiveness, all speak for themselves. The manifold applications of the Andasol-ET collector in projects in Spain and Egypt confirm the success of this collector in commercial operation.
