This report presents the results of this study. These results are presented in three successive parts. The first part provides general information on underground storage, with a focus on unlined mined caverns. The second part is dedicated to mined, lined rock caverns for hydrogen storage. The third part deals with the applicability of the mined, lined rock cavern concept to eleven planned hydrogen hubs. The applicability assessment considers prospective cavern locations based on the nearest potentially suitable surface geology to the planned hydrogen hubs. Screening for protected and urban areas has been applied, but further assessments would require more in-depth analysis and community consultation. {"type": "Polygon", "coordinates": [[[112.0, -44.0], [154.0, -44.0], [154.0, -9.0], [112.0, -9.0], [112.0, -44.0]]]} 112.0 154.0 -44.0 -9.0 Hydrogen Project Hydrogen Storage Resource geoscience Resourcing Australia’s Prosperity Review Storage ammonia storage cost Download the report (pdf) [10.3 MB] documentDigital Download the report (pdf) [10.3 MB] PDF
