I am a bit suspect about storing co2 underground. I mean what is the common leakage rate? These storages will become the green house source of the future, or not?
They claim that it will react with basalt (specifically, the calcium in the basalt formations they are pumping it into) to form calcite minerals. Honestly, even if it's only sequestered for a hundred years (a geological eyeblink) that will give us some breathing space at least.
