Energy Dome and its carbon dioxide batteries
Energy Dome is developing a grid-scale energy storage solution that uses compressed carbon dioxide to store power for up to 24 hours. By using thermal storage and gas compression, the system helps balance intermittent renewable energy sources like wind and solar without requiring specific geological conditions.
Why it matters
Long-duration energy storage is critical for stabilizing power grids as the world transitions to renewable energy sources that are subject to weather-related fluctuations.
Climate change and energy Energy Dome and its carbon dioxide batteries Energy Dome is using the gas to deliver cheap long-duration energy storage for the grid.
There’s a growing need for long-duration storage to meet energy demand and balance out renewables on the grid. Energy Dome uses compressed carbon dioxide gas in its massive grid batteries, which can deliver power for up to 24 hours.
As the world races to meet growing electricity demand, solar and onshore wind power have become the cheapest and quickest-to-deploy sources to install on the grid. But, despite their upsides, both are subject to variations in weather patterns, which means supplies can be intermittent. Energy Dome is using stored carbon dioxide to help smooth out gaps between supply and demand.
