Grid-Scale Bubble Batteries Will Soon Be Everywhere

Energy Dome has developed a grid-scale CO2 battery in Sardinia, Italy, which stores renewable energy in a massive bubble. Google is investing in this technology for its data centers, aiming to provide clean energy even when renewable sources are scarce. The CO2 battery can store energy for over 8 hours, longer than lithium-ion batteries, and is expected to be 30% cheaper.
