This book offers a thorough analysis of the mechanical properties, heat transfer, and flow characteristics as well as the monitoring techniques during the construction and operation of underground salt cavern gas storage, with an emphasis on the geological features of layered salt rocks. This information can serve as a theoretical foundation and technical guide for the underground salt cavern gas storage project. Taking into account theoretical innovations and their engineering applications, this book establishes a fundamental framework for salt cavern energy storage and covers practically every process involved in building and operating of the salt cavern energy storage. These processes include rock mechanical properties, water solution mining, gas injection for debrining, gas injection and withdrawal operation, tightness evaluation, stability assessment, operation optimization, and safety monitoring. Field engineers, researchers studying energy storage in salt caverns, and undergraduate and graduate students are the target audience for this book.

Presents in-depth analysis and practical guidance for underground salt cavern gas storage Is an essential resource for engineers, researchers, and students in the fields of energy storage Establishes a fundamental framework for salt cavern energy storage
