China has connected its first 100-megawatt compressed carbon dioxide energy storage facility to the grid in Xinjiang, offering a zero-carbon, long-duration storage alternative that does not depend on geological features like pumped hydro or compressed air storage. The project improves grid stability by storing excess electricity during off-peak hours and dispatching clean power at peak times, supporting renewable integration.
