A 300MWh compressed air energy storage system capacity has been connected to the grid in Jiangsu, China, while a compressed air storage startup in the country has raised nearly US$50 million in a funding round.
Chinese state media reported a few days ago that the large-scale project in Jiangsu Province’s Changzhou City has become operational and connected to the grid last week on 26 May.
