Parabolic Trough Plants

Amongst CSP technologies, trough systems are the most mature and have a long track record that demonstrates their reliability in large scale applications. Trough systems have been running since the 1980s and in that time have seen dramatic improvements in performance and cost. Currently there are more than 300 MW of trough systems in operation with 400 MW under construction and approximately 6 GW in development.

  • Concentrated Solar Power: CSP can be easily integrated into conventional power cycle plants or combined cycles at low additional cost.
    Electricity from CSP technology is generated in a way thermodynamically similar to conventional electricity generation. The only difference is that a solar field is used to provide heat instead of a boiler running on fossil fuels.
  • Concentrated Solar Power: CSP is nearly ideal for supplying peak electricity demands
    The characteristics of solar energy are nearly ideal for supplying peak electricity demands through the course of a day and year. During recent summers, the peak demands for electricity has been far greater than winter peak demands. This is largely due to the use of air conditioning. When air conditioners are being used during the hottest time of day in the summer is when CSP plant are able to provide the most electricity.
  • Concentrated Solar Power: CSP energy can be managed with hybridization and storage
    Solar energy is easily converted into electricity during daylight hours. By using storage tank or a hybrid fossil fuel system, CSP plants can provide clean and consistent electricity during non-daylight hours as well. Tanks and hybridization between solar energy and fossil fuels, a solar plant assures a clean and consistent production of energy throughout the day.

Abengoa Solar has extensive experience with solar trough technology. We are leaders of the Eurotrough and DISS projects. Currently, Abengoa Solar is constructing two 50 MWe plants (Solnova I and III) with hundreds of MWe of CSP in development.

Much of Abengoa Solar designs much of its own proprietary technology. The structure used for CSP troughs, Solúcar TR, was designed by Abengoa Solar NT, and the mirrors are manufactured at Abengoa Solar's Rioglass Solar factory.

The technology

Image

Parabolic troughs that track the sun on 1-axles are used to concentrate solar radiation onto receiver tubes located at the parabola's focal point. A working fluid, currently a synthetic oil, flows through the receiver tube and absorbs the radiation as heat. The heat absorbed by the oil is used to produce steam and drive a conventional power cycle.


Research and development

Abengoa Solar invests a lot of time and effort toward R&D to improve CSP plant costs and performance. Research is currently being done at a demonstration facility to improve working fluids (i.e. synthetic oils), develop high efficiency receiver tubes, and improve the Solucar TR structure.
