Okay, you've captured all this 'evil' CO2.
Like the dog who caught the car, what are you going to do with it?
It is a colorless, odorless, heavier than air gas that, in large quantities snuffs out animal life, prevents engines from starting (as if it matters, because there would be no one to drive the vehicle anyway).
A large leak would quietly kill everyone in the plume, from insects to humans and all that wildlife, even Bambi. I reckon the windmills just aren't killing enough critters fast enough.
Some say they want to inject it into the earth, even though injecting frac fluids is 'bad' because they allege it ruins groundwater and causes earthquakes. The same people who don't want oil pipelines, want to transport massive quantities of CO2 by pipeline...
And the people who babble about the 'greening' of the Planet, would be removing plant food from the atmosphere.
None of this makes any sense if the objective is to benefit humans.
