Climeworks carbon dioxide capture device

Not at all. Depending on how much CO2 it removes per unit energy expended, it may very well be feasible to power it with fossil fuels and still come out carbon negative -- we're just seeing the first iteration. (Thermodynamically, separating out CO2 is "cheaper" in terms of negentropy usage than combustion + mechanical energy extraction so the ratios are favorable.)

And even if not, and even if it only made sense with a clean-energy input, you would still only need to power that one engineering project's infra with the clean energy, which is much more feasible than replacing the entire world's infra.

A one-time giant solar array with CO2 condenser is still easier than all the infra swapout (which has its own CO2 costs) and international coordination necessary to end CO2 emissions.

it may very well be feasible citation needed.

Coal power plants which have much higher than normal CO2 concentrations in their smokestacks have looked into carbon capture and they can't pull it off without killing their power output.

Now, if we limit Fossil fuels to say Aircraft and Boats then we already solved the problem because their are a lot of natural and man made carbon sinks like your local dump. They are not enough simply because of the scale of fossil fuel usage.
