China (中国) connected its first 100-megawatt-class compressed-carbon-dioxide energy-storage project to the grid, marking a deployment milestone.

The reported milestone is grid connection of a compressed-carbon-dioxide energy-storage project. It appears in the October 3 summary of Xinwen Lianbo (新闻联播), which identifies the installation as China’s first project of its kind in the 100-megawatt class.

The capacity wording describes a power class, not a precise storage-energy specification. The supplied source says “100-megawatt-class” rather than giving an exact power rating, and provides no megawatt-hour capacity or storage duration.

The source supports a deployment milestone but little further technical analysis. It does not identify the project’s location, owner, investment cost, efficiency, or commercial-operation status, and it does not connect the project to a particular data center.
