For UHS in water-wet saline aquifers, H2 displaces in-situ brine during injection; during well shut-in and H2 withdrawal, brine imbibes back into the flow paths where it displaces some H2. These processes are influenced by H2-brine transport physics, H2-brine-rock interactions and injection\/withdrawal schemes, which, in turn, determine H2 storage capacities and injection\/withdrawal efficiency. However, these effects are poorly understood. Therefore, this work focuses on the impact of relative permeability hysteresis (RPH), wettability, and H2 withdrawal rate on UHS performance in a saline aquifer. Furthermore, differences between UHS and CO2 geo-storage (CGS) are examined. The primary findings include: 1) RPH results in a smaller H2 withdrawal factor (H2-WF), but a larger H2 withdrawal purity (H2-WP); 2) H2-WF increases with rock hydrophobicity, while H2-WP is mostly insensitive to rock wettability; 3) under similar storage conditions, H2-WF and H2-WP are approximately 10% less than CO2-WF and CO2-WP. These insights demonstrate the significance of RPH and rock wettability on UHS performance and provides guidance on H2 injection\/withdrawal scheme optimization. This study aids in the implementation of an industry-scale hydrogen economy.<\/span><br \/>\n<span style=\"color: #000000;\"><img class=\"wp-image-61996 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/11\/word-image-61995-1.png\" \/> <img loading=\"lazy\" class=\"wp-image-61997 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/11\/word-image-61995-2.png\" width=\"743\" height=\"860\" \/> <img loading=\"lazy\" class=\"wp-image-61998 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/11\/unnamed-file-36.png\" alt=\"\u56fe\u793a\n\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" width=\"746\" height=\"988\" \/><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Impacts of relative permeability hysteresis, wetta<span class=\"more-link\"><a href=\"http:\/\/learncmg.cn\/?p=61995\">Continue Reading<\/a><\/span><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[159],"tags":[392],"_links":{"self":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/61995"}],"collection":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=61995"}],"version-history":[{"count":0,"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/61995\/revisions"}],"wp:attachment":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=61995"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=61995"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=61995"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
