China launches world’s largest first compressed air facility
China has successfully launched the world’s largest compressed air energy storage (CAES) facility in Hubei province. This 300-megawatt plant utilizes underground salt caverns to store renewable energy, capable of reducing coal consumption by 45,000 tons and carbon emissions by 109,000 tons annually. This non-lithium technology provides a sustainable, long-duration storage solution that stabilizes the grid and enables greater integration of wind and solar power. The project demonstrates a scalable, eco-friendly alternative to chemical batteries, marking a pivotal advancement for global clean energy infrastructure.
