The reason we don't have clean energy ready to use is that the cost of renewable generation plus storage is currently higher than the cost of burning natural gas. If you add the cost of capture to the cost of natural gas, that's plausibly not going to be the case anymore. And then it's more cost effective to build storage than capture.

That's the point though? You use carbon-capture as energy storage (when you have excess clean energy), and you can release CO2 when you don't have enough clean energy. In an idealized process, you basically produce coal as a form of "energy storage".
