The chemistry and potential reactivity of the CO 2 -H 2 S charged injected waters at the basaltic CarbFix2 site, Iceland
The CarbFix2 project aims to capture and store the CO2 and H2S emissions from the Hellisheiði geothermal power plant in Iceland by underground mineral storage. The gas mixture is captured directly by its dissolution into water at elevated pressure. This fluid is then injected, along with effluent ge...
