Ironic discovery of the day: Middle East could be the key to reducing atmospheric CO2

Posted by Rich Sweeney on November 7, 2008

From Green Car Congress:

Researchers at Columbia University’s Lamont-Doherty Earth Observatory have concluded that the in situ carbonation of peridotite, a type of rock found at or near the surface in Oman and other areas around the world, could consume more than 1 billion tons of CO2 per year in Oman alone, affording a low-cost, safe, and permanent method to capture and store atmospheric CO2.

Their studies show that the rock reacts naturally at surprisingly high rates with CO2 to form solid minerals, and that the process could be speeded by multiple orders of magnitude with simple drilling and injection methods. The study appears in this week’s early edition of the Proceedings of the National Academy of Sciences

H/T to Tmoney.

    When is “Peak Peridotite” expected? ie this would obviously be a stop gap at best
