Neptune Energy Discovers Massive Lithium Deposit in Germany, Enough for Millions of EV Batteries
Neptune Energy has discovered a significant lithium deposit in Germany's Altmark region, potentially yielding eight million metric tons of pure lithium. This find could power batteries for millions of electric vehicles. The company aims to establish a second pillar in critical raw materials, having previously focused on gas and oil production.
Neptune Energy, led by Andreas Scheck in Germany, has been exploring the Altmark region since 2024. Their exploration licenses have revealed approximately 43 million metric tons of lithium carbonate equivalents. The company uses direct lithium extraction from deep water, bypassing traditional open-pit mining or evaporation ponds. This method is also being pursued by competitor Vulcan Energy.
In August 2025, Neptune Energy conducted a pilot test with technology partner Lilac. They successfully extracted battery-grade lithium using an ion exchange process. The next phase involves a demonstration to test a fully integrated extraction plant on a commercial scale. If confirmed, this deposit would rank among the largest project-related lithium reserves worldwide.
Neptune Energy's discovery in the Altmark region could significantly boost Germany's lithium supply. With the potential to extract eight million metric tons of pure lithium, it could power batteries for millions of electric vehicles. The company's innovative extraction method and successful pilot test pave the way for a commercial-scale demonstration. This discovery underscores the region's potential for lithium supply, as noted by Andreas Scheck, Neptune Energy's CEO.
