Vulcan Lithium Hydroxide Project Advances as German Construction Begins

Vulcan Lithium

Vulcan lithium hydroxide project development has moved into major construction in Germany, marking a key step for Europe’s domestic battery materials supply chain. Australian-listed Vulcan Energy has started building its 24,000 t/yr Lionheart lithium hydroxide project in the German state of Hesse.

The Vulcan lithium hydroxide project is scheduled to produce first output in 2028. The construction start follows Vulcan’s receipt of a six-year commercial production licence for the facility in March.

The Vulcan lithium hydroxide project is strategically important because Europe remains heavily dependent on imported lithium chemicals for battery manufacturing. Local lithium hydroxide production could support electric vehicle, battery cell and cathode supply chains across the region.

Vulcan plans to produce battery-quality lithium from low-impurity geothermal subsurface brines. The company will use direct lithium extraction technology, linking lithium production with geothermal resource development in the Upper Rhine Valley.

Geothermal Brines Support Europe’s Local Lithium Strategy

The Lionheart project is part of Europe’s broader effort to build domestic critical minerals capacity. Lithium hydroxide is a key input for high-nickel cathode chemistries used in electric vehicle batteries.

Vulcan’s route is different from conventional hard-rock lithium mining or evaporation pond production. The company plans to extract lithium from geothermal brines, then process it into battery-quality lithium hydroxide.

This matters because direct lithium extraction can reduce land use and accelerate processing compared with traditional evaporation routes. However, DLE projects still face technical and commercial execution risk because each brine system has different chemistry and operating requirements.

Construction of the surface extraction plant at Landau in the Upper Rhine Valley began in February. This upstream extraction work is critical because the lithium hydroxide plant depends on reliable brine supply and stable lithium recovery.

The project’s low-impurity geothermal brine base could give Vulcan a useful advantage if it can scale the process reliably. Battery customers require consistent quality, traceability and long-term supply security.

Public Funding Highlights Strategic Battery Materials Push

The Lionheart project received around €104mn in funding from Germany’s federal government and the states of Rhineland-Palatinate and Hesse last year. This public support shows how lithium processing has become an industrial policy priority in Europe.

Germany has a major automotive industry and is expanding battery manufacturing capacity. Domestic lithium hydroxide production could reduce exposure to overseas conversion hubs and strengthen regional supply resilience.

The project also fits Europe’s push to localise more of the battery value chain. Mining or extraction alone is not enough. Europe needs lithium chemicals, cathode materials, battery cells, recycling and downstream qualification with automakers.

Vulcan’s 24,000 t/yr planned capacity would not satisfy Europe’s full lithium demand. However, it could become a meaningful regional source if production starts as planned in 2028.

The next challenge is execution. Vulcan must complete construction, prove DLE performance, operate the geothermal brine system and qualify lithium hydroxide with battery customers.

The Metalnomist Commentary

Vulcan’s construction start shows that Europe’s battery supply-chain strategy is moving from policy ambition to industrial buildout. The project’s success will depend on whether geothermal brine extraction and lithium hydroxide conversion can scale reliably enough to meet automotive-grade standards.
