Climate change breakthrough as Iceland turns carbon dioxide into stone
'Carbon capture can contribute significantly to reducing carbon dioxide emissions' :-
A radical breakthrough in tackling climate change has been made after scientists found a rapid way to turn heat-trapping carbon-dioxide into rock.
The exclusive two year project, called CarbFix, pumped a carbon dioxide and water mix 540m underground into basalt rock at the Hellisheidi geothermal power plant in Iceland.
The acidic mixture dissolved the rocks' calcium magnesium and formed limestone, permanently and naturally trapping the gas, according to Juerg Matter of the University of Southampton and the lead author of a study detailing the experiment.
The results, published on Thursday in the journal Science, are hoped to offer a new and effective weapon to help fight man-made global warming.
"It's no longer a gas," Dr Matter said. "Basically carbon dioxide is converted into stone."
