Technology Transfer through the Foundation of an Enterprise
(31. October 2013)

CSP Services GmbH - Enhancing the quality and performance of solar thermal power plants

CSP Services GmbH was spun off in 2007 by the Solar Research department of the DLR Institute  of Technical Thermodynamics. The Cologne-based company offers engineering services, consultation as well as a range of special measuring systems for use by developers, operators and owners of solar thermal power stations. 

The measuring equipment offered by the company uses techniques such as photogrammetry, deflectometry as well as a number of innovative analytical methods and simulations. Applications in the area of concentrated solar technology also include the trialling of prototypes, quality control, assessment and performance enhancement of solar fields and their components (parabolic troughs, heliostats, Fresnel systems, dishes). CSP Services GmbH helps users minimise their technology risks while also improving their earnings and their competitiveness in the fast-growing market segment of large-scale solar thermal power plants.

In 2012, CSP Services GmbH was nominated as one of the finalists in the “Startup” category of the German Founders Award.


SOWARLA - Solar-assisted water treatment

SOWARLA GmbH was spun off in 2011 by the Institute of Solar Research of the German Aerospace Centre (DLR) and the laboratory equipment manufacturer Hirschmann Laborgeräte GmbH.
The company is located in Eberstadt. It specialises in the field of solar-assisted water treatment, offering services that include consultation, planning, and development as well as sales and operation of solar water treatment systems.
Bearing the same name as the company itself, the product, SOWARLA, is a solar powered water treatment system that uses solar radiation in a photocatalytic process to break up toxic compounds into highly bioavailable minerals.  SOWARLA was developed especially for the treatment of industrial waste water as an efficient alternative to UV oxidation, ozone treatment or catalytic oxidation, and above all as a replacement for energy-consuming methods such as combustion.
Its main component is a new kind of solar receiver. It uses solar radiation to generate the process energy that is necessary for eliminating a large variety of harmful substances from waste water. In comparison to classical UV oxidation, SOWARLA® saves 90-95% energy, avoids the emission of mercury and uses considerably less chemicals.

The basic technology for the SOWARLA water treatment system was developed by scientists at the DLR Institute of Solar Research. Their work was funded by the Federal Ministry of Education and Research and the environmental foundation Deutsche Bundesstiftung Umwelt DBU.
