Storage and reservoir management - Hydrogen storage in souther italy: an overview of potential salt cavern sites across the messinian units
Salt caverns offer a promising option owing to their low investment cost, high sealing potential and low cushion gas requirement. In Italy, natural gas storage in underground reservoir has been practiced for decades but the hydrogen storage is still at its infancy as currently no sites for hydrogen storage exist in Italy. In this contribution we explore the option of salt caverns across the territory. Messinian evaporitic units scattered across the Apennine represent the best option and therefore we do explore the feasibility of hydrogen storage in salt caverns in (active or dismantled) onshore salt mines. We do analyse the structural and stratigraphy and mineralogical context of the Messinian evaporitic units across selected onshore subsurface salt mines (Southern Italy), with a focus to the pure Halite units and mixed Halite/ Kainite Units with thickness 200 m and at depth range of 200-600 m. For the suitable sites we discuss the various site, their energy densities (cavern storage potential divided by the volume) and their relevance for hydrogen storage potential.Co-auteur : Iacopini D. 1 , Anzelmo G. , Edlmann K. , Cascone M. , Russo G. 1 Maniscalco R. , Parente M. 1 , Sabatino C. , Di Benedetto C. , , Colella A. 1 , Balassone P., Cappelletti, P , Giovannelli , D., Simili M.
