Session 15: Natural hydrogen: New geological energy Co-Conveners: HAN Shuangbiao(China University of Mining and Technology, China); HORSFIELD Brian (GEOS4, Germany); PRINZHOFER Alain (GEO4U, Brazil); WAITE David (The University of New South Wales, Australia), HU Qinhong (China University of Petroleum, China); MENG Qingqiang (Petroleum Exploration and Production Research Institute, Sinopec, China) Description: As a sustainable and renewable primary energy source, natural hydrogen (geo-hydrogen) is gradually becoming the focus of global energy research. The success of natural hydrogen exploration and development in Mali, shows its industrial development potential. The United States, Australia, France and other countries have carried out special natural hydrogen exploration and resource evaluation work, and Science listed "Hunt for natural hydrogen heats up" as one of the top ten scientific breakthroughs in 2023. Our current understanding about the natural processes leading to natural hydrogen's formation and occurrence is rather vague, especially when it comes to quantitative and economic considerations. The formation mechanisms and enrichment modes of natural hydrogen, the preservation of natural hydrogen, and the development of detection and exploitation technologies all need our attention. This session welcomes and invites global scientists engaged in natural hydrogen research to submit abstracts to participate in the discussion of the earth's natural hydrogen resources.
