    let’s assume 100% of this CO2 was generated from fossil fuels and eventually will be released into the atmosphere.

    is that any less green than grid storage batteries built from massive amounts of mined metals with an enormous CO2 footprint?

      From the IEEE article

      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.
