Has anybody actually done this on any scale yet.

Here’s a Vox piece on a successful carbon-neutral natural gas plant: https://www.vox.com/energy-and-environment/2018/6/1/17416444...

That’s a small pilot plant, I did ask at any scale.

I know I’m being sceptical but CCS has been talked about in the UK for a long time and we haven’t been able to move forward on it for some reason. I now worry that it is mostly a distraction from other technologies and changes that we know will work.

Generating all of our baseload power with renewables isn’t exactly a more plausible short-term solution. The energy storage problem is outright enormous. We don’t know that any of it will work because we haven’t done any of it at scale, that’s why we still have the problem.

What has been proven to work at scale is nuclear.

Technology is also approaching from the opposite side, producing synthetic fuels from captured CO₂ or atmospheric CO₂.

Though you would want to use cheap, non-hydrocarbon-based electricity to do this in the first place. But this does provide a mechanism for safe, civilized countries to have nuclear power and essentially export their energy to less secure countries we may not trust with that technology.
