The diagram illustrates the conceptual model for the<br/>CO<sub>2</sub> tagging and storage demonstration site. “Dead”<br>CO<sub>2</sub> is tagged with atmospheric concentrations of CO<sub>2</sub><br/>before mixing with water and underground injection. The<br/>low pH dissolves basalt in the rock, which then<br/>precipitates out as carbonate. The CO<sub>2</sub> content of samples<br/>from the monitoring well is used to determine the extent of incorporation of CO<sub>2</sub> in the carbonate.
