Experiment ‘turns waste CO2 to stone’ – BBC News

Scientists think they have found a smart way to constrain carbon dioxide emissions – just turn them to stone.

The researchers report an experiment in Iceland where they have pumped CO2 and water underground into volcanic rock.

Reactions with the minerals in the deep basalts convert the carbon dioxide to a stable, immobile chalky solid.
