China sets a new world record for the duration and reliability of artificial cave gas storage operation.

China Energy Engineering Corporation announced on the 25th that it has completed a large-scale in-situ test of artificial cavern gas storage in Changsha, creating a new world record for the operation time and reliability in this field. The test achieved the world's highest level of 18 megapascals ultra-high pressure gas storage and continuous stable operation for a "500-hour" period. The daily leak rate was below one-thousandth, setting a new world record for operation time and reliability in this field. This signifies that China has made a breakthrough from single technology to a complete process system solution, fully mastering the complete capability of artificial cavern gas storage from scientific research exploration to industrial practice.
