China Green Development Investment Group’s liquid-air energy-storage demonstration project connected to the grid, with 60 MW of storage power capacity.

The national demonstration project recently connected to the grid and generated electricity. Financial_Express, citing Science and Technology Daily, attributes the announcement to China Green Development Investment Group, which invested in and built the project. The disclosed storage power rating is 60 megawatts.

The report makes specific claims about technology ownership and equipment sourcing. It says the project uses technology with fully independent intellectual-property rights and that its equipment is 100% domestically sourced. These are reported project attributes, not independently documented supply-chain findings in the supplied material.

The source describes the installation as the world’s largest liquid-air energy-storage project. It says the project ranks first globally within that technology category for both storage power and stored-energy capacity, but provides no numerical energy-capacity figure or discharge duration. The 60-MW power rating therefore should not be presented as an energy quantity in megawatt-hours.
