It’s not just expensive, it also doesnt work unlesss almost all energy used world wide is carbon neutral. This is because carbon removal is the reverse of a reaction used to gain energy, so it needs higher input energy than was gained by the power plant.

It would be really great if we had fusion.
But for now, excess solar energy is interesting to dump into carbon capture, since we currently have no way to store it.
