If it’s powered by fissile fuels, it’s literally worse than nothing. If it’s powered by renewables then instead of powering the carbon capture plant, we could be using that same power to reduce dependence on fossil fuels which would cause less carbon to get into the atmosphere in the first place than you could remove with the plant. Until we’re at the “okay we’ve stopped the bleeding now we need to reverse the damage” phase, carbon capture is a pointless endeavour that only exists so that corporations can say “see? Doesn’t matter that we’re polluting, we’ll just fix it with magic technology!”

Edit: just realized that I and the article are talking about two different things. I’m talking about carbon capture plants, article is talking about carbon capture at the source. That’s what I get for not reading the article before commenting.
