Impact of deep-ocean carbon sequestration on atmospheric CO2
... Estimates of this sequestration potential beyond a few hundred Gt C are highly speculative. [4] The oceans have the ability to permanently store several thousand Gt C. Carbon dioxide that is sequestered in the ocean would be liquefied first and injected at a depth of 3000 m or so, either from seabed ...
