Vulcan Energy Secures Key Lithium License as Construction Accelerates and Financing Nears Final Sign-Off

Vulcan Energy secures LiThermEx license, removing regulatory risk for Lionheart. €2.2B financing and Siemens backing accelerate construction toward 2028 production.

Vulcan Energy Resources has crossed a critical regulatory threshold, receiving the LiThermEx license — the first commercial permit for lithium production from geothermal brines in the Rhine Valley. The approval transforms what was once a permitting exercise into a full-blown construction and delivery project, sharply reducing the regulatory risk that had long hung over the Lionheart development.

With all major building and production permits now in hand, the company is shifting from developer to operator-in-the-making. That transition is being underpinned by a €2.2 billion financing package (A$3.9 billion) assembled from 13 lenders, including the European Investment Bank, which is contributing around €250 million. The sheer size and composition of the syndicate signals strong institutional confidence in the project’s bankability — a rare feat for a new European raw-materials venture.

Siemens has also stepped in as a minority investor, signing a framework agreement that sees Siemens Financial Services join a dedicated consortium. In parallel, the German industrial giant has been named Vulcan’s preferred supplier for automation and digitalisation technology through 2035, adding both capital and technical credibility.

The pace of physical construction is picking up. In April, ground was broken on the central lithium chemicals plant at the Industriepark Höchst in Frankfurt, with Hesse’s premier and Frankfurt’s mayor attending the ceremony. Meanwhile, work is under way on a combined geothermal and lithium extraction facility in Landau, and preparations for a fourth production site are already under way. Drilling has advanced to the sixth production well; the fifth, LSC-1, yielded flow rates of 105–125 litres per second, consistent with the field development plan. A V10 drill rig is scheduled to be mobilised in the second half of 2026.

All this activity comes at a cost. Vulcan burned through €76 million in the first quarter of 2026, spending on land acquisitions, milestone payments to contractors, and the construction of an organic Rankine cycle power plant. Cash reserves shrank from €523 million at the start of the year to €364 million, with a further €63 million tied up in security deposits. The first phase of Lionheart targets annual output of 24,000 tonnes of lithium hydroxide, with commercial production slated for 2028.

On the commercial side, the offtake portfolio is effectively fully placed. Contracts are in place with Umicore, LG Energy Solution, Stellantis and Glencore. The largest single agreement is with Stellantis, which will take 128,000 tonnes of lithium hydroxide over ten years. LG Energy Solution has signed up for 31,000 tonnes over six years, and Glencore for up to 44,000 tonnes over eight years, partly at a floor price.

Despite the operational progress, the stock remains under pressure. Shares are trading at around €2.33, some 41% below the 52-week high set last October, and have fallen roughly 11% year to date. Analysts at Canaccord Genuity reiterated a buy recommendation in late April, and the consensus target price of €4.45 implies potential upside of about 91%. Still, the share price continues to trade below its long-term moving average, reflecting investor wariness until the final financing for Lionheart is formally closed — a milestone Vulcan aims to reach in the second quarter of 2026.

The next major event on the calendar is the annual general meeting on 28 May in Perth, where CEO Cris Moreno will update shareholders. For now, the focus is on maintaining construction momentum, securing the final financing sign-off, and proving that the company can execute on its plan to become Europe’s first commercial lithium producer from geothermal sources.
