Using Solar Thermal Energy for Power Generation, Desalination and other Applications

Research in solar thermal spans a wide spectrum, from high-temperature concentrating technologies (central receiver, parabolic trough, and Fresnel system) to low-temperature technologies.

In central receiver systems, research is focused on development of innovative particle heating receiver designs for high temperature applications. This research aims at using solid particles (such as silica sand) as the heat collection and energy storage media, such that temperatures approaching 1000 °C can be achieved. This research is conducted in conjunction with Sandia National Laboratories and several international partners.

Research in parabolic trough collectors aims at improving receiver performance of small parabolic trough systems that can be used for process heat applications, such as desalination, steam generation, or cooling. Several innovative solutions are being developed to maximize the benefit of using solar energy in this niche industry.

In Fresnel collectors, research is focused on developing a novel point focus Fresnel technology that promises high efficiency, potentially high temperature, low cost, and local manufacturing. Several prototypes have been designed and built, and work is ongoing to improve this technology to reach the commercialization stage.

The research group also conducts research on low-temperature stationary collectors, especially for desalination using solar stills and membrane distillation.
