On April 27, 2026, China inaugurated its first salt cavern hydrogen storage project in Pingdingshan, Henan Province, aiming for a capacity of 1.5 million standard cubic meters. The project leverages high-quality salt rock resources from China Pingmei Shenma and features contributions from the Chinese Academy of Sciences, CNPC, and Sinopec.
Currently, it employs two compressors to inject hydrogen at 15 MPa and 2,000 standard cubic meters per hour. The project validates the engineering feasibility of hydrogen storage in layered salt rocks, signaling advancements for the hydrogen energy sector and potential applications in hydrogen-blended natural gas and heavy-duty vehicle fuel.
