The problem: Emissions
All that Carbon, captured during more than 3.000.000 centuries is being suddenly
released during last 2 centuries:

How can we reduce the emissions that cause climate change?

Thermosolar Energy: key technology for achieving the decarbonization of the industry as it
is able to produce Electricity or Heat around the clock.

Parabollic mirrors and receiver tubes
Quality and long-term performance stability have a decisive
influence on the overall plant performance
The Receivers and Mirrors:• Are the most important but also one of themost sensitive components in a CSP Plant.

• Need to be resistant to mechanical andthermal stress.
• Need to show long-term performancestability and keep maintenance costs low
during operation.

unsupported areas producing local surface deviations)• Rigid mechanical continuous back support, including tailored inserted attachment nuts
• Standard size: 3.210 x 1.350 mm (4.3sqm),

2% more energy input on the tower means 2% less solar field to get the samepower and thus 2% net cost reduction for the project, improving the IRR.
