They may save us yet: Scientists found a way to turn our carbon emissions into rock

By Chris Mooney | The Washington Post

Earlier this year, a project in Iceland reported an apparent breakthrough in the safe underground storage of the principal greenhouse gas, carbon dioxide — an option likely to be necessary if we’re to solve our global warming problem.

The Carbfix project, run by a leading Icelandic producer of geothermal power, Reykjavik Energy, announced that it had successfully injected 250 tons of carbon dioxide, dissolved in water, into an underground repository of volcanic rocks called basalts — and that the carbon carbon dioxide hadn’t just stayed there. No — it was way better than that. Instead the carbon dioxide had apparently become one with the basalt, undergoing a fast chemical reaction and forming a type of rock called a carbonate in two years’ time.
