Iceland will try to convert CO2 into rock

Posted on April 21, 2009. Filed under: climate, environment, research & development, science & technology | Tags: , , |

Engineers in Iceland will scale-up experiments to convert carbon dioxide into rock by pumping a carbon dioxide solution into layers of basalt about 400-700m below ground, in the expectation that it will be converted to a solid carbonate that could trap the CO2 for millions of years.  So reports The Guardian, April 16, 2009.

In a project called Carb-fix, CO2 from an Icelandic geothermal energy plant will be dissolved in water under high pressure; the solution will then be pumped into the basalt layers.  Lab experiments indicate the solution will interact with calcium in the basalt to form solid calcium carbonate  This could be a safe medium for storing this “greenhouse gas”.  

The project is scheduled to begin pumping the solution in August; it’s expected to be a year before the team will know if the CO2 is converting to calcium carbonate as expected.  –nks
