China Energy Construction announced on the 25th that it has completed in-situ testing of large-scale artificial chamber gas storage in Changsha, setting a new world record for longevity and reliability in this field. The test completed verification of the world's highest level of 18 MPa ultra-high pressure gas storage and “500 hours” continuous and stable operation with an ultra-long cycle. The daily leakage rate was less than 1/1000, setting a new world record for operating time and reliability in this field. This indicates that China has achieved a leap from individual technological breakthroughs to full-process system solutions, and has fully mastered the complete ability of artificial chamber gas storage from scientific research exploration to industrial practice.
