Sequestration “profoundly unfeasible”

Climate Progress reports on the recent paper “Sequestering carbon dioxide in a closed underground volume (by Christine Ehlig-Economides and Michael J. Economides)” in the Journal of Petroleum Science and Engineering.

The paper’s calculations show that the amount of space required to store captured carbon is many times more than previously estimated, making the the whole idea “profoundly unfeasible”.  Pumping carbon back underground “is not a practical means to provide any substantive reduction in CO₂ emissions”.

Better to leave the carbon underground in the first place.  There’s no putting the genie back in the bottle.
