The partnership strengthens both companies' geothermal offerings, producing sustainably-sourced minerals and opens up a new area within geothermal power production for Climeon, waste heat recovery at existing power plants.

The collaboration will see Climeon and Geo40 strengthen their geothermal offerings and enable an expansion into waste heat recovery at existing geothermal power plants, so-called bottoming cycles. The companies will be working together to establish a first combined mineral extraction and power production plant during 2020.

Geo40 has developed a technology to extract silica and other minerals from geothermal brine, the hot wastewater that remains after high-temperature geothermal power production. The silica in the brine causes scaling in geothermal pipes and wells and limits the heat that can be extracted and utilised for power generation.

By extracting and removing the silica and other valuable minerals like lithium, Geo40's technology reduces operating costs for geothermal power stations, while producing sustainably-sourced minerals. The filtered water from Geo40's application can then be utilised in Climeon's Heat Power modules to produce clean electricity and increase power output at geothermal power stations.

Bringing together the two firms' technologies opens up a wide range of global opportunities, particularly in recovering waste heat from existing geothermal power plants, so-called bottoming cycles.

"We're happy to announce this strategic collaboration with Geo40. By combining our Heat Power modules with Geo40's technology for the extraction of silica and valuable minerals we can strengthen our geothermal offering and open up a new part of the geothermal market," said Thomas Öström, CEO of Climeon. He continued: "Combining our technologies will enable us to better address the geothermal bottoming cycle market as we together increase the output from existing geothermal power plants while solving many of the issues that geothermal brine brings."

John Worth, CEO of Geo40, commented: "We believe that our patented technology for silica removal combined with Climeon's technology for waste heat recovery is an exciting development for the geothermal industry and will be exploring the possibilities of a first common project."

More than half of the world's geothermal power plants have waste heat in Climeon's temperature range that is currently not utilised for power production. By partnering with Geo40 to remove the silica from the brine, the waste heat can be used for power production, which opens up a new part of the geothermal market for Climeon.
