It doesn't matter how high the price on CO2 is if you can't capture 1 unit of CO2 without emitting >1 unit. There's no guarantee that such a technology exists.

I've recently started hearing phrases like that despite technology X existing. What has changed recently that people have become so ignorant?
Have you ever thought of where all those fossil fuels came from? They had to be captured by plants without emitting more CO2 than they captured. The bigger problem with industrial CO2 capturing processes is that they merely capture it, they still have to store them for millions of years just like plants did when they were turned into coal or oil.
This doesn’t make sense. Plants captures CO2 by expending more (solar) energy than is released by burning coal/oil and releasing that CO2. So if we manage to produce enough clean energy to start turning CO2 into oil, we might as well stop burning oil altogether and just use that clean energy instead!
The energy requirements of sequestration processes may be significant. In one paper, sequestration consumed 25% of the plant's rated 600-megawatt output capacity. After adding CO2 capture and compression, the capacity of the coal-fired power plant is reduced to 457 MW.
In carbon capture and sequestration enhanced oil recovery (CCS EOR), carbon dioxide is injected into an oil field to recover oil that is often never recovered using more traditional methods.
