China's salt cavern utilization industry has huge development potential. Reasonable, orderly development of the salt cavern utilization industry adapting to local conditions is an effective way to ensure energy security and assist the development of new energy. At present, China's salt cavern utilization only has applications in gas storage and compressed air energy storage, and there is a lack of systematic analysis of the medium-and long-term development direction of salt cavern utilization. In order to evaluate the development prospects of China's salt cavern utilization industry, the medium-and long-term development direction and trend of the salt cavern utilization industry are analyzed based on the market demand, economic benefits and technical maturity, taking into consideration the current status of the industrial chain and the possibility of large-scale salt cavern utilization. The research results show that:1)The scale of development of China's salt cavern utilization industry will become increasingly larger, and the medium-and long-term salt cavern utilization volume is expected to reach 30×106~50×106 m³;2)Gas storage is the salt cavern utilization aspect with the largest increment, and energy storage is the salt cavern utilization aspect with the largest growth rate;3)The salt cavern utilization industry will further develop in a diversified direction, and new applications such as hydrogen storage, helium storage and oil storage will gradually be implemented, achieving a breakthrough in the new direction of salt cavern utilization.
