"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.”


And wave power, which can complement wind and solar power. It is great because the endless ocean surface is the energy storage - transporting energy through time - , and at the same time transports energy through space.
Look up the Pelamis wave energy converter. Bought by E.ON , a fossil company. Then, E.ON killed the project.
Now, apparently the Chinese have copied it and are building it. What a grim joke.
Or maybe China was involved, too, in killing the project? I don’t know.
