However, intermittency and sessional availability of renewable energy sources, as well as the demand for energy at different times and places, require a medium- to long-term storage technology. Underground hydrogen storage in saline aquifers could be a good option given the storage capacity and availability of aquifers in different geological settings. However, saline aquifers may suffer from many operational, geological, and geochemical complications. In this paper, we attempted to evaluate the need of cushion gas (nitrogen, methane, and carbon dioxide) on the success of hydrogen storage in saline aquifers.<\/span><br \/>\n<span style=\"color: #000000;\">Hydrogen storage in the saline aquifer can be simulated through CMG software. There are relevant features which are present in the simulator for the hydrogen storage. WINPROP-CMG is the compositional software which works on the basis of EOS (equation of state). The results obtained from simulating a realistic reservoir model indicated that that carbon dioxide and methane injection both were outperformed than nitrogen in terms of water displacement, cumulative injection and production. Considering the certain operational and economic aspects, injection and production cyclic mode provided the acceptable remaining gas volume and cumulative gas compared to the cushion gas scenarios, therefore, cyclic gas injection would be a promising approach to overcome the gas contamination issue. Keywords: Hydrogen, geological storage, aquifers, cushion gas, cyclic injection.<\/span><br \/>\n<img class=\"wp-image-60407 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/05\/unnamed-file-43.png\" alt=\"\u56fe\u8868 \u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n<img class=\"wp-image-60406\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/05\/unnamed-file-42.png\" alt=\"\u62a5\u7eb8\u4e0a\u7684\u6587\u5b57 \u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n<img class=\"wp-image-60408 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/05\/unnamed-file-44.png\" alt=\"\u56fe\u8868 \u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n<img class=\"wp-image-60409 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/05\/unnamed-file-45.png\" alt=\"\u624b\u673a\u5c4f\u5e55\u622a\u56fe \u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n<img class=\"wp-image-60410\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/05\/unnamed-file-46.png\" alt=\"\u56fe\u8868, \u76f4\u65b9\u56fe \u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n<img class=\"wp-image-60411\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/05\/unnamed-file-47.png\" alt=\"\u8868\u683c \u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u6c22\u6c14\u4f5c\u4e3a\u4e00\u79cd\u4e3b\u8981\u7684\u80fd\u6e90\u8f7d\u4f53\uff0c\u5728\u91cd\u5de5\u4e1a\u8131\u78b3\u4e2d\u53d1\u6325\u7740\u91cd\u8981\u4f5c\u7528\u3002\u8003\u8651\u5230\u542b\u6c34\u5c42\u5728\u4e0d\u540c\u5730\u8d28\u73af\u5883\u4e2d\u7684\u50a8\u5b58\u80fd\u529b\u548c\u53ef<span class=\"more-link\"><a href=\"http:\/\/learncmg.cn\/?p=60405\">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":[346],"_links":{"self":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/60405"}],"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=60405"}],"version-history":[{"count":0,"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/60405\/revisions"}],"wp:attachment":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=60405"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=60405"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=60405"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
