Value Creation in Icelandic Geothermal Processes: Extraction of minerals and metals
- W2V-15-06-001
Coordinator: Sunna Ólafsdóttir Wallevik, Gerosion ehf
Project will finish in 2017


ISK 32.6 M



For utilization of geothermal energy, project co-ordinators meet with corrosion and scaling issues in geothermal wells and power plants. Both can lead to mechanical failures and decreased power production. The precipitation of dissolved minerals from the geothermal fluid causes clogs in wells, wellheads, pipes and heat exchangers. The project investigates available commercial technologies that can be used for the isolation of minerals. Secondly, investigation of non-commercial options will be explored with the focus on relevance to Icelandic reality. The potential extraction products will also be studied, mainly regarding material properties, market value and potential local applications.

The different geothermal areas in Iceland will be analysed regarding the potential for mineral extraction, as it is known that the geothermal fluid composition is different in different geothermal regions.
