It seems kind of unlikely. It could be part of an array of solutions. Right now it captures something like 0.1%. That means it would take 1000 times the current infrastructure to support it, including carbon-neutral energy to cover the additional energy costs. All that is assuming 100% carbon capture is even viable. Even then, that doesn’t solve the problem of the carbon that’s already in the environment, which will continue to warm the earth for centuries.
There’s an interesting emergency option: Stratospheric aerosol injection.
If we got to the point where the runaway effect was unavoidable, it might be possible to use this before civilization starts to collapse. It would probably have a lot of nasty side effects, but it might be able to buy enough time for CO2 levels to come back down. At least civilization could survive in some form.
