Well, it isn't going to sink enough CO2 to move the needle:

> If the worst happens and the dome is punctured, 2,000 tonnes of CO2 will enter the atmosphere. That’s equivalent to the emissions of about 15 round-trip flights between New York and London on a Boeing 777. “It’s negligible compared to the emissions of a coal plant,” Spadacini says. People will also need to stay back 70 meters or more until the air clears, he says.

So it's really just about enabling solar etc.

It has nothing whatsoever to do with sinking CO2.

		I understand this, but it coincidentally uses CO2 and it's hard for me to understand why the technology would sound "too good to be true" without imagining such a purpose.

It’s a battery not a sequestration technology.
