HENGILL VOLCANO, Iceland - In the heart of Iceland's volcano country, 21st-century alchemists are transforming carbon dioxide into rock for eternity, cleaning the air of harmful emissions that cause global warming.
The technology mimics, in accelerated format, a natural process that can take thousands of years, injecting CO2 into porous basalt rock where it mineralizes, capturing it forever.
"With this method we have actually changed the time scale dramatically," says geologist Sandra Osk Snaebjornsdottir.
