In addition to electrical energy the Climeworks process requires hot water at 100 °C and cooling water at -15 °C. Climeworks Plants are engineered for integration of customer utilities if available to optimize energy consumption. In the absence of available heating and cooling Climeworks offers pre-engineered optional solutions.
Future direct-air capture plants will cost up to $400 per metric ton of captured carbon dioxide to operate, Gebald said, with carbon sequestration adding an additional $10-$20 to that cost per ton.

It would appear the energy requirements of running these things would be substantial in both heating and cooling. I'd suspect that currently it would mean producing more carbon for the energy to run these in most area's and I don't find anything explaining how that would counter the CO2 reduction to get a real number.
On a large scale they would require a great deal of energy from current power plants to both heat and cool the water and increase the demand on existing power plants.
Somehow I think the voluntary planting of many more trees in denuded areas of the world would do far more good, for far less money.
Maybe fifty years from now this would be affordable.
Sorry, having trouble getting this to post.
There is an additional problem, the elephant in the room, where to store all that CO2.
But in recent research, this expected thickness hasn’t been found: A 2012 study of fossilized raindrops, for example, found that Earth’s early atmosphere was as little as half as thick as it is today.
From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25.

Dinosaurs that roamed the Earth 250 million years ago knew a world with five times more carbon dioxide than is present on Earth today, researchers say, and new techniques for estimating the amount of carbon dioxide on prehistoric Earth may help scientists predict how Earth's climate may change in the future.

Yeah, pollution is good for you. It clears your lungs like cigarettes do.
