The success of carbon capture and storage (CCS) depends on the ability to safely and permanently store CO2. For the first time, scientists working with a power plant in Iceland have demonstrated a way to pump CO2 into basalt rocks and turn it from gas to an environmentally benign carbonate mineral. Over 95 percent of the CO2 injected into the CarbFix site in Iceland was turned to a solid in less than 2 years, the scientists report in a recent study. This result contrasts with the common view that the immobilization of CO2 as carbonate minerals within geologic reservoirs takes several hundreds to thousands of years. The results demonstrate that the safe long-term storage of anthropogenic CO2 emissions through mineralization can be far faster than previously postulated.
