Hydrogen is considered a viable energy vector, it can be produced through the electrolysis of water and stored as a gaseous phase in the subsurface. Hydrogen storage in saline aquifers is not yet commercially operational, to increase the technological readiness, the complex interactions between rock, pore fluid, and hydrogen under reservoir conditions (increased pressure and temperature) need thorough understanding. It is acknowledged that abiotic geochemical reactions are a potential barrier for UHS as hydrogen is an electron donor and can form highly reactive hydrogen ions. Using a comparative approach, this study reviews the current disparity in the literature regarding the impacts and extents of hydrogen-induced abiotic reactions, to identify knowledge gaps requiring further investigation. Data from both experimental and modelled methods are summarised in relation to individual minerals, common in the subsurface, and their implications to efficiency and security of underground hydrogen storage. This review demonstrates a significant agreement concerning the lack of reaction between hydrogen and rock-forming silicate minerals, and a strong likelihood that under reservoir conditions (heightened temperature and pressure) hydrogen can reduce pyrite to pyrrhotite. It also reveals compelling evidence suggesting exposure to hydrogen can lead to the dissolution of sulphates (anhydrite) and carbonates (calcite). We conclude development of future hydrogen storage projects in saline aquifers should therefore focus on silicate-rich formations. And further work is needed to establish a clear understanding of extents and rates of potential mineral reactions to ensure storage security and efficiency in future projects.

氢诱导矿物蚀变:咸水层地下储氢 (UHS) 背景下的综述
氢气被认为是一种可行的能源载体,它可以通过电解水产生并以气相形式储存在地下。咸水层中的储氢尚未投入商业运营,为了提高技术准备,需要彻底了解储层条件(压力和温度升高)下岩石、孔隙流体和氢之间的复杂相互作用。众所周知,非生物地球化学反应是 UHS 的潜在障碍,因为氢是电子供体,可以形成高反应性氢离子。本研究使用比较方法回顾了当前文献中关于氢诱导非生物反应的影响和程度的差异,以确定需要进一步调查的知识差距。来自实验和建模方法的数据总结了与地下常见的单个矿物及其对地下储氢效率和安全性的影响有关的数据。这篇综述表明,氢与形成岩石的硅酸盐矿物之间没有反应,并且在储层条件(温度和压力升高)下,氢极有可能将黄铁矿还原为磁黄铁矿。它还揭示了令人信服的证据表明,暴露于氢气会导致硫酸盐(硬石膏)和碳酸盐(方解石)的溶解。因此,我们得出结论,未来咸水层储氢项目的开发应侧重于富含硅酸盐的地层。需要进一步的工作来清楚地了解潜在矿物反应的程度和速率,以确保未来项目的储存安全性和效率。
