Researchers Turn CO2 Into Stone in Climate Change Breakthrough

Researchers in Iceland found a new way of tackling climate change by pumping carbon dioxide underground and turning it into stone. Other carbon capture and storage (CCS) methods store CO2 as a gas, but problems include a high cost and concern about leakage. This new method of burying CO2 and turning it into stone is cheaper and more secure, the Guardian reports. To turn C02 to stone, researchers with the Carbfix project pumped the gas into volcanic rock and sped up the natural process in which basalts react with gas and form carbonate minerals.
