BrineMine Project Looks at Geothermal Resources for Extraction of Energy, Raw Materials and Fresh Water

Northern Chile, one of the driest regions on the earth, has extensive geothermal resources. With innovative combined cycle power plants (CCPP), climate-friendly electricity can be generated and fresh water and mineral resources extracted at the same time. To this end, the German-Chilean research project “BrineMine”, funded by the German Federal Ministry of Education and Research, was launched in 2019 to develop strategies and technologies in this field. As part of the project, the Fraunhofer Institute for Solar Energy Systems ISE is developing the plant technology for subsequent industrial use. Part of the process chain has already been successfully demonstrated in operation in a geothermal power plant in the Upper Rhine Graben.
