“…The time period for the development of a salt cavern based on the areal extent of salt formation and formation hydraulic diffusivity, however, might take more than 1 year to construct a single cavern. , The drilled hole which could be used for the injection of H 2 based on the factors, including geological formations, structure, fault locations, and depth of the salt caverns (which typically range from 300 to 2000 m). Like in oil and gas well drilling, the salt cavern wells are also drilled in a telescopic design; however, the diameter of salt cavern wells is larger when compared to conventional oil and gas wells . These caverns are cased and cemented adequately so that H 2 gas will not leak and a smooth H 2 injection/production cycle is sustained …”

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.

“…[5][6][7][8] Sequestration is known as the process of injecting and storing CO 2 in geological subsurface storages over a geological time frame such as in depleted oil and gas reservoirs, coal beds, salt caverns and saline aquifers. [9][10][11][12][13] It is a viable option to cope with CO 2 from large industrial emitters (e.g. conventional power plants, steelworks, cement plants and other large emitters) as well as CO 2 mitigation technologies, such as bioenergy coupled with CCS (BECCS), direct air capture (DAC) and others.…”

With the demand to reduce the release of CO2‐rich gases into the atmosphere, the offshore industry is turning to systems for gas capture and storage. The construction of a cave for that purpose is planned in the salt layer of the Santos Basin, Brazil; however, numerous factors bring uncertainties to the project. We propose combining systems engineering methods and digital twin technology to enable system concept and execution aiming at value robustness. The system is modeled in mission, subsystems, components, and design attributes. System utilities and costs are estimated for a range of viable solutions based on the relevance of each attribute to the stakeholders. The alternatives are evaluated using the Epoch‐Era Analysis framework for analyzing the system's performance over time in changing future scenarios. The system model also outlines a digital twin concept and identifies how it might support salt cave design and operations. Finally, the potential of tuning and improving system evaluation based on gathered data is examined, and measures toward further digital twin development are recommended.
