Back to Earth – Using Natural Processes to Turn CO2 Permanently into Rock

The CarbFix collaborative research project, led by Reykjavik Energy, centers around one of the world's largest geothermal power plants in Hellisheidi, Iceland. Industrial scale application of the CarbFix process has been ongoing at the power plant since 2014 with 66,000 tons of sour gases captured and injected at the end of 2018, 2/3rd of which were CO2 and 1/3rd H2S. This accounts for over 40% reduction in emissions from the geothermal power plant. The fact that the CarbFix CCS process allows for co-capturing and mineralizing other environmentally important gases like sulfur, provides significant added value to the method.
