This is a nice sentiment that I agree with as a sentiment, but it's not realistic.

If it takes the equivalent of 1ton of carbon emissions to capture 1ton of carbon emissions, you are literally going nowhere compared to just replacing fossil fuels.

So this technology needs to be extremely efficient, otherwise the amount of extra energy generation we need - on top of what we already have, renewable or not - becomes astronomical. So far it does not look anywhere close to being sufficiently efficient.
