This study investigated the impact of cushion gas type and presence on performance underground hydrogen storage (UHS) in an offshore North Sea aquifer. Using numerical simulation, relationship between UHS was comprehensively evaluated, providing valuable insights for designing efficient project delivery. Results indicated that can significantly process's recovery efficiency purity. CO2 found to have highest capacity, while lighter gases like N2 CH4 exhibited better efficiency. Utilising as a lead higher 80%. It also determined utilising either these always more beneficial than alone, leading incremental up 7%. Additionally, purity degraded each cycle progressed, but improved over time. contributes understanding factors affecting inform selection optimal operational strategies.

This review presents a State-of-Art of geochemical, geomechanical, and hydrodynamic modelling studies in the Underground Hydrogen Storage (UHS) domain. Geochemical assessed reactivity hydrogen respective fluctuations losses using kinetic reaction rates, rock mineralogy, brine salinity, integration redox reactions. Existing geomechanics offer an array coupled hydro-mechanical models, suggesting decline failure during withdrawal phase aquifers compared to injection phase. Hydrodynamic evaluations indicate critical importance relative permeability hysteresis determining UHS performance. Solubility diffusion gas appear have minimal impact on UHS. Injection production cushion deployment, reservoir heterogeneity however significantly affect performance, stressing need for thorough experimental studies. However, most current efforts focuses assessing aspects which are crucial understanding viability safety In contrast, lesser-explored geochemical geomechanical considerations point potential research gaps. Variety software tools such as CMG, Eclipse, COMSOL, PHREEQC evaluated those underlying effects, along with few recent application data-driven based Machine Learning (ML) techniques enhanced accuracy. identified several unresolved challenges modelling: pronounced lack expansive datasets, leading gap between model predictions their practical reliability; robust methodologies capable capturing natural subsurface while upscaling from precise laboratory data field-scale conditions; demanding intensive computational resources novel strategies enhance simulation efficiency; addressing geological uncertainties environments, that oil simulations could be adapted comprehensive offers synthesis prevailing approaches, challenges, gaps domain UHS, thus providing valuable reference document further efforts, facilitating informed advancements this towards realization sustainable energy solutions.
