The Global South: An Underground Hydrogen Storage site dataset

To develop our understanding of UHS, its potential applications, and its place in future green energy systems, criteria relating to geological suitability and techno-economic feasibility from a wide range of data sources are collected in a unified dataset. Scientific publications, industry reports, technical reports and national databases are all considered. Entries into the dataset are each compiled with dates, source publications, geographic locations and current statuses alongside site characteristics. The storage sites considered are strictly subsurface structures including hydrocarbon fields, aquifers and salt caverns. This dataset is intended to motivate future work, aiming to provide the groundwork for further studies in UHS adoption as input data for preliminary site selection frameworks, system modeling and policy decisions.
