This study presents a benchmarking of requirements and a comprehensive framework for site screening of saline aquifers for hydrogen storage. It integrates technical parameters – such as reservoir quality, seal integrity, and geomechanical stability – with non-technical aspects, including economic viability, regulatory readiness, environmental risk, and social acceptance. Particular focus is given to hydrogen-specific challenges affecting storage integrity, especially geochemical and geomechanical factors. Drawing from experience with natural gas and CO2 storage, the study proposes a multidisciplinary screening workflow to support early-stage project assessment. The findings provide a foundation for future pilot projects, policy development, and regulatory frameworks tailored to UHS in porous media, contributing to the strategic expansion of hydrogen infrastructure and energy system resilience.
