“…However, these energy resources (e.g., wind, solar, and tide) are time-, season-, weather-and/or region-dependent, which limits their stability, reliability and large-scale economic implementation [4][5][6]. To overcome these drawbacks, underground hydrogen storage (UHS) is considered as a promising solution [7][8][9][10][11]. When energy supply is larger than energy demand, excess renewable and sustainable energy can be converted to hydrogen (H2) through water electrolysis as a green energy carrier, and the H2 can be injected into the subsurface for storage; when energy demand is high, H2 can be withdrawn again from the subsurface for usage [12][13][14][15][16][17].…”

Geological H 2 storage plays a central role to enable the successful transition to the renewable H 2 economy and achieve net-zero emission in the atmosphere. Depleted oil and gas reservoirs are already explored with extensive reservoir and operational data. However, residual hydrocarbons can mix with injected H 2 in the reservoirs. Furthermore, low density and high diffusivity of H 2 may establish H 2 leakage from the reservoirs via fault pathways. Interestingly, H 2 can be consumed by microorganisms, which results in pore-network precipitation, plugging, and partial permeability impairment. Therefore, stored H 2 may be lost in the formations if the storage scenario is not planned cautiously. While salt caverns are safe and commercially proven geo-rock for H 2 storage, they have low-storage capacity compared to depleted gas reservoirs. Moreover, salt structures (e.g., domel, bedded) and microorganisms activities in the salt cavern are limiting factors, which can influence the storage process. Accordingly, we discuss challenges and future perspectives of hydrogen storage in different geological settings. We also highlight geographical limitations with diverse microbial communities and theoretical understanding of abiotic transformation (in terms of rock's minerals, i.e., mica and calcite) for geological H 2 storage. Regarding the fundamental behavior of H 2 in the geological settings, it is less soluble in formation water; therefore, it may achieve less solubility trapping compared to CO 2 and CH 4 . Furthermore, H 2 gas could attain higher capillary entrance pressures in porous media over CH 4 and CO 2 due to higher interfacial tension. Additionally, the low viscosity of H 2 may facilitate its injection and production but H 2 may establish the secondary trapping and viscous fingering. Thus, this review documents a blend of key information for the amendment of subsurface H 2 storage at the industrial scale.

“…Hydrogen may react with the initial air-water component to indirectly affect pH and promote mineral dissolution/precipitation. The associated undesirable gas (H2S) will have a negative effect on hydrogen quality [62]. These harmful gases promote the redox reaction and dissolution of hematite (Eq2) [63].…”

As a clean, efficient energy source, hydrogen is regarded as a promising alternative energy for accomplishing the zero-CO2 targets. In the longer term, large-scale hydrogen geologic storage (HGS) could reduce the instability of intermittent energy sources, through peak cutting and valley filling. However, the low density and viscosity of hydrogen and its interaction with the surrounding rocks and microbes constrain the effective advancement of large-scale HGS. This paper summarizes the current research status, feasibility analysis, advantages and disadvantages of HGS in the main potential reservoirs (depleted oil/gas fields, salt caverns, and brine aquifers). In addition, the uncertainties and challenges are also addressed for HGS application in the future: 1) Operating parameters, which are difficult to determine and evaluate, have a significant impact on HGS efficiency. For example, the cyclical injectionreproduction and injection rates have large impact on H2 fingering phenomenon and the geological integrity of the caprocks; 2) Currently, the hydrogen-water-rock geochemical reactions at various temperatures and pressures are not well understood well. There is a lack of a geochemical reaction database to meet the HGS numerical simulation requirements. The associated reactions could cause uncertain changes in porosity and # This is a paper for the 8 th Applied Energy Symposium -CUE2022, Sept. 24-27, 2022, Matsue, Japan.
