MinWaterCSP Provides Technical Solutions for Efficient Water Use in CSP Plants

8.11.2018

The international research and development project MinWaterCSP addresses the challenge of reducing the water consumption of CSP plants and improving thermal cycle efficiencies of Concentrated Solar Power (CSP) plants. After three years of work, 13 partners from 6 different EU and non-EU countries have developed new technologies for reducing water consumed for cooling and mirror cleaning. During the 2nd International Conference on the “Reduction of Water consumption in CSP plants” in Stellenbosch, South Africa (7-8 November 2018), the consortium presents its final results.

CSP test facility at the Stellenbosch University, South Africa.

At this occasion, the full-scale test facility dedicated to the testing of an axial flow fan and novel delugeable heat exchanger was inaugurated at the Stellenbosch University. More than 75 CSP stakeholders from six countries representing, amongst others, owners of power plants/power utilities, technology suppliers, research institutions and NGOs participated in the event.

The Fraunhofer Institute for Solar Energy Systems ISE presented new heat exchanger concepts for air-cooled condensers, water treatment concepts and mirror cleaning. An expanded version of the Fraunhofer ISE simulation software ColSimCSP enables the simulation of water use, wastewater streams and the treatment processes at CSP plants. Furthermore, the loop-wise high-resolution simulation of mirror cleaning in the solar field with the aim of optimizing the water management plan is possible.

MinWaterCSP has received funding from the European Union’s Horizon 2020 research and innovation programme. It is coordinated by Kelvion Holding GmbH (Project Coordinator, Germany) and ENEXIO Management GmbH (Technical Coordinator, Germany). The project will be completed in December 2018.
