Abstract

This collection of research addresses critical aspects of underground hydrogen storage (UHS) essential for a hydrogen-based energy economy. Studies examine the geological and engineering considerations for utilizing depleted oil and gas reservoirs and saline aquifers, alongside the crucial role of caprock integrity and advanced monitoring techniques. The influence of microbial activity and geochemical reactions on storage efficiency and reservoir performance are investigated. Furthermore, techno-economic analyses of repurposing existing infrastructure, the advantages of salt caverns, and the integration of hydrogen storage with natural gas networks are explored. The impact on reservoir wettability and fluid flow, as well as long-term performance modeling, are also key areas of focus, collectively contributing to the safe and effective deployment of large-scale hydrogen storage solutions.
