摘要:

随着全球对清洁能源需求的增长, 氢能作为重要的可再生能源储备, 其储存技术受到广泛关注。陆上储氢系统存在氢气泄漏、污染饮用水和灾变伤人等风险。而海下岩层地质环境相对稳定, 密闭性好, 海下离岸储氢技术受到广泛关注与快速发展。目前主要的地下储气技术包括盐穴、含水层和枯竭油气藏储气库3种, 其中盐穴储气库在欧美多国已经运行多年, 技术基础较为成熟, 然而我国滨海并无适合建设盐穴的地层, 盐穴储氢库只能在内陆建设。我国滨海地下含水层和油气藏较为丰富, 亟须及时开展海下储氢的相关地质研究, 推动不同海域相关技术的发展和应用, 以及氢能产业的全面发展。发展海下储氢技术不仅在选址过程中需要运用最新的地球物理方法, 结合氢气特殊的物理化学特性, 详细评估海下特殊的地质条件, 同时要综合考虑地质、水文、生物化学和矿物学等因素, 以确保合理规划和安全运行。

Abstract:

With the growing global demand for clean energy, hydrogen energy, as an important renewable energy reserve, has garnered widespread attention for its storage technology. Onshore hydrogen storage systems pose risks such as hydrogen leakage, drinking water contamination, and catastrophic injuries. In contrast, offshore geological environments are relatively stable and well-sealed, leading to widespread attention to and rapid development of offshore hydrogen storage technology. Currently, the main underground gas storage technologies include salt caverns, aquifers, and depleted oil and gas reservoirs. Salt cavern gas storage has been operating for many years in Europe and the USA and has a relatively mature technical foundation. However, there are no suitable locations for constructing salt caverns along China’s coast, which limits the build-up of salt cavern hydrogen storage to inland regions. However, China’s coastal areas have abundant underground aquifers and oil and gas reservoirs, necessitating timely related geological research to promote the development and application of relevant technologies in different marine areas and the comprehensive development of the hydrogen energy industry. Developing offshore hydrogen storage technology requires not only integrating the unique geological conditions of the margin with the special physical and chemical properties of hydrogen, but also considering geological, hydrological, biochemical, and mineralogical factors to ensure a rational planning and safe operation, in addition to using the latest geophysical methods in site selection. Looking ahead, offshore hydrogen storage technology will not only provide theoretical support for the development of renewable energy technologies in China but also play a significant role in promoting a low-carbon, green, and sustainable development.

Key words: hydrogen storage, offshore, salt cavern, aquifer, oil and gas reservoir
