[SMM Hydrogen Energy News Brief: China's First Million-Cubic-Meter-Level Salt Cavern Hydrogen Storage Demonstration Project Put into Operation in Henan] On April 25, China's first million-cubic-meter-level salt cavern hydrogen storage demonstration project, led by the Wuhan Institute of Rock and Soil Mechanics under the Chinese Academy of Sciences, was officially put into operation in Pingdingshan City, Henan Province.

This project marked China's first hydrogen storage facility built in bedded salt rock formations, identifying the multi-scale migration patterns of hydrogen in ultra-low-permeability rock salt, overcoming the core technology of precise site and layer selection for salt cavern hydrogen storage, and effectively verifying the long-term sealing performance and engineering application feasibility of hydrogen storage in bedded salt rock.
