Abstract

Carbfix is the cost-effective and environmentally benign proprietary industrial technology to capture carbon dioxide (CO2) and other sour gases from emission sources and permanently store it as solid minerals in the subsurface. The process can furthermore be applied in relation to direct capture of CO2 from air. The technology was developed and proven at Hellisheidi geothermal power plant in Iceland where over 95% of CO2 captured and injected was transformed into minerals in the subsurface in less than two years through natural processes. This contrasts the previous common view that mineral storage in carbon capture and storage (CCS) projects takes hundreds to thousands of years. The Carbfix process has now been operated at an industrial scale at the Hellisheidi geothermal power plant since 2014. The process can be applied widely on a global scale in the power and industrial sectors and preparations are already underway to apply the process at several new sites in e.g. Iceland, Italy, Turkey and Germany, partly in relation to geothermal operations. The Carbfix technology provides the geothermal sector with a proven, economic and environmentally benign solution to further decrease its carbon footprint which in turn increases the competitiveness of the sector. Carbfix provides interested parties with consulting and access to its rock-solid, proprietary climate solution.
