Analysis of the Possibility of Carbon Dioxide Storage in China’s Underground Salt Caverns

Abstract

The underground salt caverns created by solution mining used for storage has great advantages over other storage methods. However, not every underground salt cavern created in China is suitable for CO2 storage owing to different reasons like water resources and the depth of salt caverns. The author searched for the geographic information of salt layers in China first. Secondly , through general analysis like analyzing salt caverns’ location and plate, some salt layers good for CO2 storage are listed. Comparing to a case studying from Australia's Otway Basin, which applies underground gas storage experience to geological carbon dioxide storage, the author analyzed the possibility of CO2 storage in Jingtan,China from different aspects mainly about the leakproofness and salt caverns stability. Some suggestions are given concerning the construction of CO2 storage in underground salt caverns at last.
