Neptune Energy and its predecessor companies have harnessed the region\u2019s geological resources since 1969. Recent data now shows that the Rotliegend brines<\/a> from the vast Altmark gas field are not only strongly mineralized but also highly enriched in lithium.<\/p>\n Sproule ERCE, which helps energy and finance stakeholders make better decisions by integrating technical, commercial and operational expertise, confirmed 43 million tons of lithium carbonate equivalent (LCE) in the area.<\/p>\n \u201cThis means that one of the world\u2019s largest project-based lithium resources is located in Northern Saxony-Anhalt,\u201d Neptune Energy, revealed.<\/p>\n For comparison, the Lithium Triangle<\/a>, shared between Argentina, Bolivia and Chile, holds 53 percent of the world\u2019s lithium resources. It contains nearly 50 million tons of the alkali metal.<\/p>\n This prompted the company to shift its focus from fossil fuels to clean, high-demand battery materials. Instead of relying on environmentally damaging methods like open-pit mining or evaporation ponds, the firm is now deploying a process known as direct lithium extraction<\/a> (DLE) from underground brine. <\/p>\n This technique is designed to minimize land use and environmental impact, and instead relies on sophisticated ion-exchange and adsorption processes to isolate lithium from brine deposits<\/a>.<\/p>\n Strategic licensing moves<\/p>\n In August 2025, Neptune Energy completed its second pilot project using DLE technology from its partner Lilac. It successfully extracting battery-grade lithium carbonate<\/a> from Altmark\u2019s geothermal brine. A third pilot test, focused on an adsorption-based process, began is currently underway.<\/p>\n If granted the necessary mining permits, Neptune plans to follow up the pilot phase with a demonstration-scale facility that integrates extraction, processing, and production. This would serve as the final step before full-scale commercial operations.<\/p>\n<\/p>\n At the moment, Neptune Energy holds the Jeetze-L production license along with three exploration licenses for lithium in the Altmark region. It received the Milde A-L and Milde C-L licenses in 2024. A year later it also obtained the Milde B-L license in the southeastern part of the region. <\/p>\n \u201cThe Altmark region combines geological potential, established infrastructure, and technical know-how \u2013 perfect conditions to successfully complete the transformation from natural gas production to environmentally friendly lithium extraction,\u201d Axel Wenke, Neptune Energy\u2019s new energy director concluded in a press release<\/a>. <\/p>\n","protected":false},"excerpt":{"rendered":"A global energy company has recently confirmed that Germany holds one of the world\u2019s largest lithium resource bases,…\n","protected":false},"author":2,"featured_media":453579,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5310],"tags":[152330,1503,2000,299,21306,1824,6503,152331,152332,90583,3695,53],"class_list":{"0":"post-453578","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-germany","8":"tag-altmark-region","9":"tag-energy-amp-environment","10":"tag-eu","11":"tag-europe","12":"tag-evs","13":"tag-germany","14":"tag-lithium","15":"tag-lithium-battery","16":"tag-lithium-brine","17":"tag-natural-resources","18":"tag-sustainability","19":"tag-technology"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/115272407616558203","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/453578","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=453578"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/453578\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/453579"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=453578"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=453578"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=453578"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"\"](\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/A11_cf345f.jpg\" "\\"43")
The company received a third exploration license for lithium in Saxony-Anhalt.
