Geological CCS

This idea has been around for a while: can we inject CO2 into the ground and wait for it to turn into calcium carbonate? In other words: mineral carbonization. Of course we can, but this geological process is considered far too slow to be useful for operation CCS as a mitigation strategy.

But, maybe not - at least for localities with suitable geology: Rapid carbon mineralization for permanent disposal of anthropogenic carbon dioxide emissions (Science, 10 June 2016).

Here's the science news version GEO-INJECTION SYSTEM CAN TURN CARBON DIOXIDE INTO STONE and the video.
