Underground hydrogen storage: Influencing parameters and future outlook

Underground hydrogen storage (UHS) is a promising technology with which large quantities of H-2 can potentially be stored in the subsurface safely, economically and efficiently. As UHS is a relatively new technology, we critically reviewed all available data related to solid properties, fluid properties and solid-fluid interactions relevant to UHS. We also provide clear conclusions, and highlight research gaps. This review therefore advances fundamental understanding of UHS at multiple physical scales and provides key guidance for UHS project operations at reservoir scale
