The ground has broken on Vulcan Energy’s Lionheart lithium project in Germany, and the developer has quietly assembled a commercial foundation that would make many of its pre-production peers envious. With a blue-chip customer roster, a freshly signed automation partner, and a regulatory sweetener from the state of Rhineland-Palatinate, the company is navigating the tricky transition from fundraising to execution.
A Customer Line-Up That Speaks Volumes
Vulcan’s offtake agreements now cover nearly three-quarters of its planned output. Stellantis has committed to 128,000 tonnes of lithium hydroxide over ten years, while LG Energy Solution has booked 31,000 tonnes across six years. Umicore takes another 23,000 tonnes over the same period, and Glencore has secured between 36,000 and 44,000 tonnes for eight years. Critically, roughly 72% of these contracted volumes are tied to fixed or floor prices, insulating Vulcan from the worst of a lithium market that has seesawed violently in recent years.
The missing piece of the supply chain puzzle was filled by Siemens. A framework agreement worth €40 million makes the German industrial giant the primary automation partner for all three Lionheart sites: the lithium extraction plant in Landau, the central lithium facility at Industriepark Höchst in Frankfurt, and the production drilling locations. Siemens Financial Services has also taken a minority equity stake, joining Hochtief and Demea Sustainable Investment. A memorandum of understanding locks in Siemens as the preferred automation supplier through 2035.
Cash Burn Takes Centre Stage
With the funding package of €2.2 billion secured since December 2025, investor attention has shifted squarely to how quickly that capital gets consumed. Vulcan’s Q1 report, released on 29 April, put operating expenses at €7.2 million, flowing mainly into staffing and development. But the pace has since accelerated. Parallel drilling campaigns are now underway at the Schleidberg and Trappelberg sites, and the main drilling phase is scheduled for the second half of 2026.
Should investors sell immediately? Or is it worth buying Vulcan Energy?
Phase One targets 24,000 tonnes of lithium hydroxide annually, enough to supply roughly half a million electric-vehicle batteries. The project also generates 275 gigawatt-hours of renewable electricity and 560 gigawatt-hours of heat for local customers as by-products, with a planned operational lifespan of 30 years. Management has already signalled that hitting the 24,000-tonne target by 2028 will require additional capital, keeping dilution firmly on the table.
A Royalty Holiday Eases the Strain
A regulatory decision from Rhineland-Palatinate grants Vulcan an exemption from lithium royalty payments until the end of 2030. The move provides financial breathing room precisely during the most capital-intensive construction phase. The project’s financing rests on multiple pillars: a banking consortium has committed nearly €1.2 billion in loans, state subsidies contribute €204 million, and strategic partners have chipped in additional equity.
The lithium market has offered some tailwinds. Battery-grade lithium carbonate in China climbed to 175,000 yuan per tonne at the end of April, a gain of nearly 50% since the start of the year. In Europe, lithium carbonate settled at $20,500 per tonne CIF, with lithium hydroxide at $19,800. Not a boom, but a clear stabilisation. New demand is emerging from operators of large data centres, whose power storage requirements are lithium-intensive.
What Investors Will Be Watching
On 28 May, Vulcan Energy holds its annual general meeting in Perth. CEO Cris Moreno will face questions on construction progress and the open questions around future capital needs. Investors will be pressing for precise answers on costs and timelines, with the company’s ability to execute now the single most important metric.
