The options for UHS include salt caverns, hard rock caverns, saline aquifers and depleted gas fields. The focus here will be on the last two options, which are also very relevant for CCS. The key similarity is that UHS and CCS in porous media both depend on injection of a gas phase which is less dense than the formation water, and so there is two-phase flow in a porous medium, and buoyancy effects are dominant away from the well. Thus, for containment one needs sites with an adequate sealing formation to prevent upward migration. There exist key differences though\u2026<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Poster: Dr Ennis-King\u2019s poster at GHGT-18 is: <em>Evolution of gas composition in the long-term storage of impure carbon dioxide: effects of convection and diffusion<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tuesday October 27, 11:30am &#8211;
