"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."

People will also need to stay back 70 meters.

Huge amounts of carbon dioxide can be far more dangerous. The Lake Nyos disaster has killed over 1700 people, at up to 25 kilometers distance.
