Title: Carbon Dioxide Tucked into Basalt Converts to Rock

Carbon Sequestration or storing carbon dioxide underground may be one approach to reducing atmospheric levels of the greenhouse gas. Storing it in basalt formations creates a chemical reaction in which the CO2 is transformed into a mineral similar to limestone enabling permanent storage underground. A field study by researchers at the Department of Energy’s Pacific Northwest National Laboratory shows that chemical happens quickly. Within two years, CO2 injected underground in Washington state had converted to the carbonate mineral ankerite.
