CO2 Sequestration - In Rock Form

If we can't get rid of CO2, the greenhouse gas that gets the most press, perhaps we can store it, say researchers.    Maybe even in rock form.     Carbon dioxide when mixed with water forms carbonic acid (also known as carbonated water or soda water), which can percolate through  rocks, dissolving some minerals and forming solid carbonates with them, thereby storing the carbon dioxide in rock form. Sigurdur Gislason of the University of Iceland has been studying the possibility of sequestration of carbon dioxide (CO2) in basalt and presented his findings today to several thousand geochemists from around the world at the Goldschmidt Conference hosted by the University of Tennessee, Knoxville, and Oak Ridge National Laboratory. read more
