Solar Plants

  • During summer, solar plants collect and store heat for use in winter. In order to save the heat for winter, an insulating material consisting of Expanded Clay Aggregate (ECA®) is used.
  • Expanded Clay Aggregate (ECA®) can as well serve as great heat-insulator; it’s flexible and easy to use.
  • Expanded Clay Aggregate (ECA®) can be applied by blowing, using a blowing hose of about 90m to the exact place of application.
  • Lightweight Expanded Clay Aggregates have been applied at Andasol plant located in the south of Spain. In an extension of 1.5 × 1.3 km² per plant, thousands of mirrors are waiting for solar radiation. During the night,
  • power production cannot stop and a salt solution at 400 ºC stores heat to continue normal power supply. This salt is in a liquid state inside a metallic tank.
  • From the results of the first use, contractors and consultants appeared  to be very encouraged.
  • Since 2006 a total of 20 plants have followed  Andasol plant. The last five plants have been constructed in Morocco and South Africa.
