    Abstract: With the advancement of China's carbon peaking and carbon neutrality ("dual carbon") goals, traditional fossil energy is being transformed into renewable and clean energy. Hydrogen energy, characterized by wide sources, high energy density and high efficiency and cleanliness, has become an important energy component in the future. Salt caverns have especially obvious advantages in terms of gas tightness, and salt does not react with hydrogen, making them the first choice for large-scale underground hydrogen storage. In order to focus on the research and future development of salt cavern hydrogen storage technology in China, we analyzed the geological types and characteristics of hydrogen storage, and elaborated on the progress of salt cavern hydrogen storage research and the current situation of foreign operations; around the salt cavern hydrogen storage technology, we analyzed the key technologies such as large-size drilling and completing wells, salt cavern cavity creation and morphology control, cavity sealing evaluation, wellbore integrity testing and evaluation, and control of tubing corrosion and hydrogen embrittlement; and summarized the relevant hydrogen energy policies and strategic goals formulated by various countries in recent years. It summarizes the relevant hydrogen energy policies and strategic objectives formulated by various countries in recent years, combines the opportunities and challenges for the future development of hydrogen storage in salt caverns in China, and looks forward to the geological selection and evaluation of hydrogen storage in salt caverns, integrity of large-size wellbore, morphology control of salt cavern cavity creation and sealing detection, and organic synergistic development of hydrogen energy and salt, with a view to advancing the scale application of hydrogen energy and the development of industrial chain. The results of the study can provide a reference for the development of salt cavern hydrogen storage.
