Pumped-storage power stations (PSPSs) can pump water from a lower reservoir to an upper reservoir when the electricity demand is low, store energy in the form of potential energy, and release the stored water into the lower reservoir to generate electricity when the electricity demand is high and are among the most mature power system technologies (Li et al., 2022).

Underground hydrogen storage (UHS) is one of the key technological solutions for balancing energy systems and promoting sustainable energy development.In this study, we propose a novel UHS method, which involves injecting hydrogen generated from electrolyzing formation water into depleted gas reservoirs through hydraulic fractures during off-peak …
Simulation models can aid in identifying an efficient design to operate such a system. With the widespread adoption of numerical simulation models as an aid in the assessment of mineral resource development projects, several jurisdictions have seen an advantage in formulating practice guidelines to promote sound application of groundwater models.
The integrated production system of coal mining, sorting and filling is used to carry out coal mining, washing and filling of gangues in the downhole, which not only improves the transportation efficiency of main shaft, but also reduces the environmental pollution caused by gangues.In order to enrich the theoretical research on the integrated production logistics …

A suitable option for Underground Hydrogen Storage (UHS) is aquifers composed of porous and permeable media. However, the successful execution and long-term safety of the UHS process require further understanding of hydrogen transport behavior in the pathway of caprock to eliminate the possibility of hydrogen leakage. In this regard, we employ Molecular …
However, these simulators struggle to accurately characterize the reactions between hydrogen and other minerals and fluids, which is crucial for ensuring the efficiency of underground hydrogen storage systems. To simulate microbial reactions in the pore spaces of underground storage media, several scholars have performed exploratory research.
