SOLWARIS

Solving Water Issues for CSP Plants

The SOLWARIS targets to significantly reduce the water used by CSP plants (by 35% for wet cooled & by 90% for dry cooled). The project proposes to demonstrate the efficiency of innovations in solar field cleaning, power-block cooling, water recycling system, and plant operation strategy. Among these are solutions to reduce solar field water cleaning needs, an operation and maintenance optimizer software including soiling forecaster, a MEE water recovery technology running on otherwise dumped heat from the solar field, and a cooling concept for the turbine condenser storing excess heat when ambient is too warm, then releasing it during cool night times.
The solutions will be implemented at two CSP operational sites, “La Africana” parabolic trough plant in Spain and “Ashalim” central receiver plant in Israel, to demonstrate a significant reduction in water use while making CSP more cost-effective, and achieving near-to-market status. The solutions are best applied together, but each will also bring water and cost savings on its own, thanks to their ability to fit any kind of CSP plant; dry, wet, or hybrid cooled, existing or future ones, tailored to location and policy framework. Their application will save more than 0.5 M€/year of operational cost for a 50 MW CSP plant.

Regarding competition on water resources and humanitarian issues, the social acceptance of CSP will be increased by detailed analysis of case studies and education of the local population to the benefits of solar energy.
The targeted savings of water and operation costs will increase CSP’s competitiveness compared to other renewable energy and the electricity market in general, as well as its acceptance within local communities, achieving a big step forward in the SET plan goals for CSP technology by 2020. The consortium, led by TSK Electrónica y Electricidad S.A. (Spain), is made up of 13 partners from 6 European countries plus Israel, including 5 industrials partners, 2 SMEs, 5 RTOs and one University.

AMIRES was involved in the project’s preparatory phase and in the negotiations. Within the project, it is responsible for administrative project management, communication, and dissemination of results.
