Title: Putting away CO2 for good: carbon
sequestration in basalts
Reducing atmospheric CO2 emissions to fight climate change is one of the prime challenges of our times. Carbon capture and storage (CCS) can contribute towards decarbonization of the global economy. The success of this solution depends on the ability to safely and permanently store CO2. Our study in Icelandic basalts demonstrates for the first time the permanent disposal of CO2 as environmentally benign carbonate minerals in basaltic rocks. We find that over 95% of the CO2 injected into the CarbFix site in Iceland was mineralized to carbonate minerals in less than 2 years. This method could be used at many continental sites and in the off-shore basaltic ocean floor.
