"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."

We had these things called Gasometers in the UK for a long time. They expanded with the amount of gas stored in them, and they kept the pressure of the local gas supply up. A local gas reservoir, or "gas battery" if you like.

These bubbles are basically the same idea but at higher pressure.
