Solar energy cost-competitive with fossil fuels
Based on extensive project experience with several concentrated solar power (CSP) plants in Denmark, Aalborg CSP further perfected its solar-thermal technology to enable worldwide availability for renewable energy that is capable of competing head-to-head with the prices of fossil fuels.
Designed for reduced capital costs and improved performance, the AAL-TroughTM 4.0 provides the industrial market segment with cost-efficient heat, power, steam, cooling and fresh water production - all fueled by the sun. This is achieved through a new, lightweight structure, improved optical accuracy, standardized and locally sourced components which enable savings in terms of transportation and installation time and costs.

Maximizing solar heat with sun-tracking technology
![](/fileadmin/_processed_/7/c/csm_AAL-Trough_4.0_sun_path_ENG_c2e02d398d.png)
The CSP parabolic trough technology applies sun-tracking curved mirrors (called parabolic troughs) to maximize the sun’s energy and consequently the efficiency of heat production. The sun's rays are captured and reflected onto a receiver pipe filled with a heat transfer fluid (water or thermal oil) that is located in the central point of the troughs. Here, the concentration and a significant better utilization of the sun’s energy is obtained.
