2<\/sub>-rich environments may contribute to corrosive mineral reactions through local pH changes and co-production of various acids.<\/li>\n<\/ul>\nLarge-scale hydrogen storage will not be possible without the delineation of expected microbial activity in these systems. Before hydrogen can be safely and securely stored in underground reservoirs, the effect of gas injection on the naturally occurring microbial community and the associated change in chemistry needs to be assessed. NETL is currently researching several targeted hydrogen storage formations for the risk of microbial consumption of H2<\/sub>; work is ongoing using the subsurface microbial communities and high-pressure-high-temperature simulation experiments to demonstrate biogeochemical changes that can be expected during subsurface hydrogen storage.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":3,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"100-width.php","meta":{"footnotes":""},"class_list":["post-242","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/edx.netl.doe.gov\/sites\/geomicrobiology\/wp-json\/wp\/v2\/pages\/242","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/edx.netl.doe.gov\/sites\/geomicrobiology\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/edx.netl.doe.gov\/sites\/geomicrobiology\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/edx.netl.doe.gov\/sites\/geomicrobiology\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/edx.netl.doe.gov\/sites\/geomicrobiology\/wp-json\/wp\/v2\/comments?post=242"}],"version-history":[{"count":8,"href":"https:\/\/edx.netl.doe.gov\/sites\/geomicrobiology\/wp-json\/wp\/v2\/pages\/242\/revisions"}],"predecessor-version":[{"id":560,"href":"https:\/\/edx.netl.doe.gov\/sites\/geomicrobiology\/wp-json\/wp\/v2\/pages\/242\/revisions\/560"}],"wp:attachment":[{"href":"https:\/\/edx.netl.doe.gov\/sites\/geomicrobiology\/wp-json\/wp\/v2\/media?parent=242"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}

<\/a>Hydrogen is emerging as a low-carbon fuel option for transportation, electricity generation, manufacturing applications, and clean energy technologies that will accelerate the United States\u2019 transition to a low-carbon economy. However, a key challenge is to ensure the safe and effective storage of hydrogen. One of the primary unknowns in H2<\/sub> storage is the impact caused by microbial communities that are naturally present in underground reservoirs at a broad range of conditions. H2<\/sub> is known to be an energetic electron donor, supplying energy for a wide variety of subsurface microorganisms, many of which have been documented to exist naturally in the geologic units that are targets for H2<\/sub> gas storage.<\/p>\n<\/div>
