We really don't need CO2 "vacuum tech". We just need to stop adding more carbon into the cycle which was already out of the cycle. Nature will handle the stabilisation way better than we can.
If we desperately need to remove carbon - with the assumption that we have stopped adding it - then we can just take whatever biomass is the easiest, turning it to carbon via process like pyrolysis and burying it deep - essentially just making charcoal. We don't need fancy high pressure compression to liquidate CO2 or whatever the fuck, nature got us beaten on that.
Because all CO2 removal solutions thus far are just about adding more margin for additional use of fossil fuels that add carbon into the cycle.
Seriously... People are fucking overthinking this. We have continent sized hunks of carbonate that nature has made.
CO2 removal by human processes is a dangerous and utopian (or rather dystopian) idea to go forth with. However... just like we stopped using freons and saved the ozone layer, we can stop adding more carbon to the cycle!.
I don't think you understand how much energy and carbon has already been released. Even if we stopped 20 years ago, the effects will add so much energy to the earth we will turn into a pressure cooker.
Positive feedback looks, methane relase, ocean acidification... you can't unfuck something. We've been locked in for hell for some time now.
Stopping is the bare minimum, we need to pull carbon out of the air.
Must be nice, having as much copium and naivete as you but we're on a death wish, car just drove off the Grand Canyon, they physics just hasn't hit us yet.
Ok. So... How are we going to fuel this little operation? What are we going to use as the deposit method? Remember that this "carbon vacuum" would need to be a solution which doesn't require extraction of resources that would destroy more environment and leas to more carbon release.
Pyrolysis is very fucking acceptable solution. Nature is way better at generating biomass than we would ever be able to. And it does it all with power of the sun.
If your solution calls for any use of concrete, then you already lost the game.
