That's quote from wikipedia. I think you're right with your calculations, so I don't really know where this number came from.

What're you going to do with that collected CO2 other than releasing it to the atmosphere?

Separating from other gasses, followed by sequestering.

I guess that it would cost a lot. Technically you can do that with traditional coal plants.

Those don't produce fuel. They produce electricity.
