Reducing industrial CO2 emissions is considered one of the main challenges of this century. By capturing CO2 from variable sources and injecting it into suitable deep rock formations, the carbon released is returned back where it was extracted instead of freeing it to the atmosphere. This technology might help to mitigate climate change as injecting CO2 at carefully selected geological sites with large potential storage capacity can be a long lasting and environmentally benign storage solution.
To address this challenge, the CarbFix project is designed to optimize industrial methods for storing CO2 in basaltic rocks through a combined program consisting of, field scale injection of CO2 charged waters into basaltic rocks, laboratory based experiments, study of natural analogues and state of the art geochemical modeling. A second and equally important goal of this research project is to generate the human capital and expertise to apply the advances made in this project in the future.
This research program includes:
1. Field scale injection of CO2 charged waters into basaltic rocks at the Hellisheidi natural laboratory. The Hellisheidi natural laboratory, situated in the Hengill area, SW Iceland, comprises ideal conditions for studying the feasibility of permanent CO2 storage as minerals in basaltic rocks due to availability of CO2 and water, the presence of fresh basalts, suitable geological structures, and an extensive infrastructure.
2. Laboratory experiments research program. The emphasis of this experimental program is to quantify basalt dissolution and carbonate precipitation rates stemming from during CO2 injection.
3. Studies of natural CO2–rich water reactivity as natural analogues to the behavior of injected CO2. A significant number of natural sites have experienced basalt interaction with CO2 charges waters. Studies of these systems provide insight into the long-term stability of basalt hosted CO2 storage.
4. Geochemical modeling. Geochemical modeling will be performed to interpret laboratory experiments and field work as well as to predict/optimize the long-term behavior of CO2 injection sites.
