A new experiment will assess the viability of storing carbon pollution underground by artificially creating seams of limestone. The India Times reported that the project will begin next month at Hellisheidi in south west Iceland, near Reykjavik Energy’s geothermal power stations.

The technique involves creating so-called seltzer water which reacts with basalt and forces the dissolved CO2 into harmless limestone. Read more
