39.48, -82.98 | CO2 is a liquid under pressure. It is typically sequestered at least 0.5 to 0.6 miles deep, where the natural pressure keeps it in this supercritical state. It is buoyant, so it requires containment. Played-out gas wells work great. In some locations, it reacts with native minerals to form carbonates, which will be stable for eons.
Sequestration does require infrastructure, pumping costs, and so on. I don't see it as a magic fix, but I suppose it is one part of an "all of the above" approach. | |

Explain Carbon sequestration to me like I am 5
