Sequestration of  carbon underground is nothing new.   Of course the big challenge of this technology is that gas always finds a way to escape, until now.   A research project in Iceland, CarbFix, has shown that when CO₂ is pumped into basalt a chemical reaction takes place that forms carbonate minerals –better known as stone.  Stone, being the solid that it is, should be able to lock away the CO₂ indefinitely.   Based on the pilot, Reykjavik Energy, is now running a larger test and is burying nearly 10,000 tonnes of CO₂ and around 7,300 tonnes of H₂S.   If this works, the world will likely be turning to tiny Iceland to solve some very big climate change issues.    For way more accurate information click here.
