[For CO2 storage to make a difference] the envisaged CO2 storage industry is comparable to the current scale of the hydrocarbon industry
lol, what.
70% of the projects proposed to be operational by 2020 were not implemented
only around 9 Mt yr−1 of a total capture capacity of 45 Mt yr−1 is injected for dedicated storage, with the rest used for enhanced oil recovery
So most of the time they just do it when it means they can get more oil.
