"This giant bubble on the island of Sardinia holds 2,000 tonnes of carbon dioxide. But the gas wasn’t captured from factory emissions, nor was it pulled from the air. It came from a gas supplier.... "The facility compresses and expands CO2 daily in its closed system, turning a turbine that generates 200 megawatt-hours of electricity, or 20 MW over 10 hours."

The CO2 is in a CLOSED LOOP system meaning its not going to be leaching into the atmosphere.

yeah, sure thing buddy. the CO2 will be in a closed loop until it won't. just like Fukushima and Chernobyl were supposed to be closed loop systems, until they weren't. disasters happen, no matter how much the techbro mindset insists that they're impossible.

The CO2 is likely harvested directly from the atmosphere

LMAO, the audacity of telling me I don't know how electricity generation works when you don't even know how to read. they're using industrial CO2 derived from fossil fuels

So you're against nuclear power too? If that's the case I'll double down on my previous statements. Being anti nuclear is simply being dumb. Tell me about how CO2 is sourced and explain how you're saying its being sourced by burning fossil fuels. What other industries use CO2 as part of process? Have you looked into CO2, how its captured, used and its necessity at all? Again, this is something I can tell you have a very surface understanding of with no problem being vocally ignorant.
