What a waste of money, ask any independent climate scientist what you could could spend £22bn on, carbon capture and storage wouldn’t even be in the top 100 suggestions.
Wait, I've seen quite a few articles claiming carbon capture was basically an oil industry myth. Are we sure we should be investing in that instead of some things which have more proven effectiveness like renewables?
The laws of physics mean that no matter what we do with carbon capture it is never going to be cheaper and less energy to emit it and then capture it again. This is a foolish endeavour the focus should be on the green transition with Wind, Solar and Storage combined with ensuring infrastructure is there for Electric Vehicle transition. This is the sort of investment the fossil fuel wants governments to make that will have no impact and allow them to continue to emit.

That's not the same as saying it'll emit more carbon than it captures, which seems to be what you're tilting at.
We need to undo the damage we have already done. Carbon dioxide has a climate delay time of about 200ish years, so it's critical that we remove historical carbon, or we are totally buggered, regardless of what we do with green energy today.
What do we do with all the carbon we capture and store? Can we use it for something else? If not then we need to stop producing it, not just sticking it into a landfill like we have with our rubbish for the last hundred years or so.
