BUCHS, Switzerland — Watersolutions AG and Technical University Berlin have received the Desert Best Paper Award for their paper “Modeling the Cogeneration of Power and Water with Concentrated Solar Power (CSP) and Low Temperature Desalination: New Approach of CSP+D Application with Innovative Low Temperature Desalination,” according to a press release.

The paper, which describes a project in El Gouna, Egypt that uses CSP and Low Temperature Distillation (LTD), was co-authored by Mark Lehmann, chief technology officer of Watersolutions AG and Johannes Wellman, Karl Neuhäuser and Frank Behrendt of the Technical University Berlin.

The Award was presented at the 3rd Annual Dii Desert Energy Conference, which took place November 7-9 in Berlin. The paper was one of only four selected from approximately 60 submissions.

The jury comprised experts from Dii and from the DESERTEC University Network.

The paper presented the model of the cogeneration process of a simplified concentrated solar power (CSP) plant with innovative low temperature desalination.

The low-temperature distillation system (LTD) was developed by Watersolutions AG and was first tested in a full-scale plant in El Gouna, Egypt, using waste heat in the cooling cycle from diesel generators at 70-85° C.

Through analyzing the measurement data of this demonstration plant, it was possible to derive the thermal and electrical behavior of this plant. This allowed the development of a simulation where the low-temperature distillation system was connected to the steam condenser of a CSP power plant.
