In a new paper in Science, representatives of Reykjavik Energy and a team of scientists from a large number of universities, including the University of Southampton in the U.K. and the Lamont-Doherty Earth Observatory at Columbia University, show not only that the process of injecting carbon dioxide into basalt rock at the Iceland site works, but that moreover, the carbon dioxide is mineralized, or turned into rock, very rapidly. In two years, they report, over 95 percent of injected carbon dioxide had become mineral.

“They made very nice progress and this paper represents a breakthrough,” added Klaus Lackner, who heads the Center for Negative Carbon Emissions at Arizona State University and who says he knows the researchers involved and helped get the project started but is not an author of the paper.
“It is an important result that the CO2 forms carbonates in a short time. Mineral sequestration underground is only useful if it happens on a human time scale.
