Article Synopsis
- Engineered CO2 removal is crucial for keeping global warming below 1.5°C, with mineral carbonation being a promising negative emissions method demonstrated in Iceland's CarbFix project.* -
- Calcium isotopes in water before and after CO2 injection help measure the amount of carbonate formed, showing that pH and calcite saturation greatly influence calcite precipitation.* -
- The study estimates that 165±8.3 tons of CO2 were converted into calcite, achieving a carbon storage efficiency of 72±5%, indicating the method's effectiveness for similar future projects.*
Basalts are recognized as one of the major habitats on Earth, harboring diverse and active microbial populations. Inconsistently, this living component is rarely considered in engineering operations carried out in these environments. This includes carbon capture and storage (CCS) technologies that seek to offset anthropogenic CO emissions into the atmosphere by burying this greenhouse gas in the subsurface.

The success of this solution depends on the ability to safely and permanently store CO2 This study 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.
