Why Renewable Energy Needs Advanced Storage Solutions As global renewable energy capacity surpasses 3,500 GW, one critical question remains: How can we store excess energy
A compressed air energy storage (CAES) project in Hubei, China, has come online, with 300MW/1,500MWh of capacity. The 5-hour duration project, called Hubei Yingchang, was built in two years with a total investment of CNY1.95 billion (US$270 million) and uses abandoned salt mines in the Yingcheng area of Hubei, China’s sixth-most populous province.
CEEC claims that the facility can store electricity for eight hours and release power over a five-hour period on a daily basis. The world's first 300-MW compressed air energy storage (CAES) demonstration plant has been connected to the grid, operating at full capacity in the central Chinese province of Hubei.
The $207.8 million facility boasts an energy storage capacity of 300 MW/1,800 MWh and occupies an area of approximately 100,000 m2. According to ZCGN, it is capable of providing uninterrupted power discharge for up to six hours, ensuring power supplies to between 200,000 and 300,000 local homes during peak consumption periods.
It claimed that the facility was 30% cheaper than the 100 MW project built by the Institute of Engineering Thermophysics and said its overall efficiency is 72%. The $207.8 million facility boasts an energy storage capacity of 300 MW/1,800 MWh and occupies an area of approximately 100,000 m2.
The “Energy Storage No. 1” project utilizes the caverns of an abandoned salt mine, reaching up to 600 meters of depth, as its gas storage facility. This allows for a gas storage volume of nearly 700,000 cubic meters, translating into a single unit power output of up to 300 MW and a storage capacity of 1,500 MWh.
The Jintan project exemplifies the potential of CAES technology to contribute to a low-carbon energy grid. By leveraging existing salt caverns for energy storage and integrating innovative designs, the project offers a sustainable solution to the intermittency of renewable energy sources.
