Google Rapidly Deploying Huge CO2 Battery Facilities That Store 200 Megawatt Hours of Power

Compressed CO2 stored in large domes can provide long-duration, grid-scale energy storage, holding roughly 200 MWh for use when renewable supply is low.

Exclusive: Fourth Power's sci-fi thermal batteries could be cheaper than pricey natural gas power plants | TechCrunch

Here's how the technology works: To store energy, electricity from the grid heats blocks of carbon inside insulated chambers filled with argon gas. When power is needed, the system pumps molten tin heated to a scorching 2,400°C (4,352°F) through graphite pipes - the only cost-effective material that can withstand those temperatures. Special solar panel-like devices called thermophotovoltaic cells then convert the heat back into electricity by capturing the white-hot tin's infrared light.
