A Critical Review on Parameters Affecting the Feasibility of Underground Hydrogen Storage

ACS Omega, Год журнала: 2025, Номер unknown

The need and demand for energy are ever increasing with the rapid urbanization of global population. Near-future economic development consequent expected industrialization strongest indicators rising requirement. Though fossil fuel coal catering toward a major chunk demand, their negative or adverse impact in terms emission greenhouse gases (GHGs) carbon dioxide (CO2) is causing warming imbalance environmental conditions, leading to search commercially viable alternate types. As renewable energies like solar wind weather-dependent, an supply needs be done even more urgently. Hydrogen (H2), being carrier not source, can deliver store significant amount energy. stored utilized generation power, electricity, heat. Further, hydrogen very pure nature therefore widely useful from flexibility efficiency standpoint. It represents predominant constituent within natural environment, totaling about three-fourths universe. Storage has gained significance recent times, subsurface storage looked upon as alternative. However, successful function critical parameters wettability, capillary pressure, relative permeability, diffusion, microbial activities, etc., which themselves dependent rock types corresponding mineralogical compositions, along associated pressures temperatures. This work critically reviews that these would have on storability subsurface, evaluates best possible solution, recommends future course action through insights derived, considered while considering underground storage.

Underground H2 storage (UHS), i.e., injecting into subsurface geological formation and its withdrawal when needed, is identified as a promising solution for large-scale long-term of H2. In this study, molecular dynamics (MD) simulation was performed at typical temperature 320 K with pressure up to 60 MPa predict transport properties H2–H2O–rock interfacial properties, which are compared those CO2 CH4. The MD results show that the CH4 profiles property variations lie between more comparable CO2. interaction H2O/silica much weaker than It found effect on altering water contact angle tension negligible under all conditions.
