Grid-Scale CO 2 Batteries will Take off in 2026: When the Sun Sets on Solar Panels, These Gas-Filled Domes Pick up the Slack
Abstract
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, and it lives permanently inside the dome's system to serve an eco-friendly purpose: to store large amounts of excess renewable energy until it's needed.
