Researchers believe that they have made a major step towards proving carbon capture and storage is viable. A team in Washington State injected liquified CO2 into a basalt formation -- rock that forms after a lava flow has cooled. Two years later, and it's claimed that the carbon dioxide has solidified into Ankerite, an inert material that should, theoretically, lock the carbon away forever. According to Scientific American, it was originally believed that it would take hundreds of years for the process to occur. The fact that it took just 24 months gives hope to the notion that the technology is workable.
