The world's largest compressed air energy storage station, the second phase of the Jintan Salt Cavern Compressed Air Energy Storage Project, officially broke ground on December 18, 2024 in Changzhou, East China's Jiangsu Province, marking a key milestone in China's energy storage advancements.What is a compressed air energy storage project?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.
What is a compressed air energy storage station?"The compressed-air energy storage station offers large capacity, long storage time (over 4 hours), and efficient response, making it comparable to small and medium-sized pumped storage power plants," Liu Yong, Secretary General of Energy Storage Application Branch of China Industrial Association of Power Sources told the Global Times on Wednesday.
What is a 300 MW energy storage plant?The $207.8 million energy storage power station has a capacity of 300 MW/1,800 MWh and uses an underground salt cave. Chinese developer ZCGN has completed the construction of a 300 MW compressed air energy storage (CAES) facility in Feicheng, China's Shandong province. The company said the storage plant is the world's largest CAES system to date.
Is China planning to use compressed air for energy storage?But according to Asia Times, China is planning to lean heavily on compressed air energy storage (CAES) as well, to handle nearly a quarter of all the country's energy storage by 2030.
How much power does a new energy storage facility provide?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.
How efficient is China's new compressed air plant?According to China Energy Storage Alliance, the new plant can store and release up to 400 MWh, at a system design efficiency of 70.4%. That's huge; current compressed air systems are only around 40-52% efficient, and even the two larger Hydrostor CAES plants scheduled to open in California in 2026 are only reported to be around 60% efficie
