摘要: 在"双碳"目标下绿色无污染、高能量密度的氢能已成为能源产业未来发展的重要趋势,地下储氢是一项很有前景的大规模氢能储存技术。通过综述地下储氢概念的提出和矿场实践研究现状,深入剖析了盐穴储氢、含水层储氢、枯竭油气藏储氢及废弃矿井储氢的储存模式及特征,从多角度对比分析了各自优缺点。天然气的地下储存可为储氢提供技术经验,但二者又存在明显区别。通过系统研究地下储氢的可行性,详细阐述了地下储氢在盖层密封性、井筒密封完整性及储层化学反应等方面存在的难点和挑战。基于以上研究和分析,指出了地下储氢发展存在的难题,展望了地下储氢的未来发展前景,提出了加强盖层地质力学完整性、井筒完整性研究以及加快储层岩石、流体与氢气的地球化学和微生物反应评估等对策建议,以期为中国氢能地下储存提供参考。

Abstract: In terms of the"dual carbon"target, green, pollution-free and high-energy density hydrogen energy has become an important trend for the future development of energy industry. Underground hydrogen storage is a promising technology for large-scale hydrogen storage. This paper describes the concept, field practice and theoretical research status of underground hydrogen storage. A deep analysis is performed on the modes and characteristics of hydrogen storage in the salt cavern, aquifer, depleted oil and gas reservoirs, as well as abandoned coal mine, of which the advantages and disadvantages are compared from multiple perspectives. Underground natural gas storage provides technical experience for hydrogen storage, but there are obvious differences between the both. Further, the paper systematically analyzes the feasibility of underground hydrogen storage, and elaborates the difficulties and challenge in terms of caprock, wellbore integrity and chemical reaction in reservoirs. Based on the above research and analysis, the difficulties in the development of underground hydrogen storage technology are clarified; the future development prospects of underground hydrogen storage have been predicted; the corresponding countermeasures and suggestions are also put forward, such as strengthening the research on the geomechanical integrity of caprock and the integrity of wellbore, and facilitating the assessment of the geochemical and microbial reactions of reservoir rocks, fluids and hydrogen, which provide a significant reference for the underground hydrogen storage in China.
