Hydrogen (H2) is currently considered a clean fuel to decrease anthropogenic greenhouse gas emissions and will play vital role in climate change mitigation. Nevertheless, one of the primary challenges achieving complete H2 economy large-scale storage H2, which unsafe on surface because highly compressible, volatile, flammable. geological formations could be potential solution this problem abundance such their high capacities. Wettability plays critical displacement formation water determines containment safety, capacity, amount trapped (or recovery factor). However, no comprehensive review article has been published explaining wettability conditions. Therefore, focuses influence various parameters, as salinity, temperature, pressure, roughness, type, and, consequently, storage. Significant gaps exist literature understanding effect organic material capacity. Thus, summarizes recent advances rock/H2/brine systems containing reservoirs. The paper also presents influential parameters affecting capacity including liquid–gas interfacial tension, rock–fluid adsorption. aims provide scientific community with an expert opinion understand identify solutions. In addition, essential differences between underground (UHS), natural storage, carbon dioxide are discussed, direction future research presented. promotes thorough knowledge UHS, provides guidance operating UHS projects, encourages engineers focus more research, overview advanced technology.
