Detection and Evaluation Technologies for Using Existing Salt Caverns to Build Energy Storage

Underground salt caverns are widely used in large-scale energy storage, such as natural gas, compressed air, oil, and hydrogen. In order to quickly build gas reserves, an unusual building method was established. The involves using the existing left over from solution mining of storages. 2007, it first applied Jintan Natural Gas Storage China. Based on this successful project, several were screened storages Engineering experience indicates that key reusing is how select most suitable numerous available confirm it. This paper summarizes reviews relevant theories testing methods, including: (1) primary selection principle for (2) evaluation theory tightness cavern, (3) typical project case storage From practical application results, proposed can screen with potential, brine injection effectively evaluate their tightness. It provides a technical roadmap subsequent implementation cavern utilization projects large scale.
