Vulcan Energy has locked down €2.2bn in financing for its Lionheart lithium hydroxide project in the Upper Rhine Valley, yet the market response has been anything but celebratory. Shares slipped to €1.99 on Tuesday, a few cents above the €50-million market cap company’s year-to-date low, and roughly 50% below the October peak of €3.98. The disconnect between the scale of the ambition and the stock’s trajectory underscores the lingering pressure on the lithium sector.
The Lionheart project, which stretches across the German-French border, aims to produce 24,000 tonnes of lithium hydroxide per annum — enough to supply roughly 500,000 electric vehicles. That would make it one of Europe’s biggest geothermal-lithium plays, well ahead of Finland’s Keliber project (15,000 tonnes/year, cold commissioning slated for Q1 2026) and trailing only France’s EMILI project (34,000 tonnes/year, which recently secured €50m in state aid). Vulcan’s financing milestone, however, has done little to lift the stock from its technical trough.
Technically, the picture remains strained. The shares are trading around 24% below the 200-day moving average of €2.61, with the relative strength index at a neutral 40.8. Since the start of the year, the equity has shed nearly a quarter of its value. The broader commodity backdrop offers no relief: lithium carbonate in China touched a ten-week low of 157,000 yuan per tonne, and rival developers such as Liontown Resources are also feeling the heat.
Should investors sell immediately? Or is it worth buying Vulcan Energy?
In a parallel move, Vulcan has sold its earlier-stage PP4 pilot plant to EAU Lithium, a subsidiary of Australia’s Cosmos Exploration, for €1m. The deal provides an immediate€125,000 up front, with the remaining€875,000 due later. The hardware will remain in Germany for now, where engineers are testing it with Bolivian brines; the buyer plans to eventually deploy Vulcan’s proprietary VULSORB direct extraction technology in South America, in partnership with state-owned YLB. For Vulcan, the sale monetises older infrastructure while expanding the geographic footprint of its extraction know-how — both goals it can pursue without distracting from the Lionheart build-out.
That build-out faces a credibility gap. AMG Lithium has already started commercial production of battery-grade lithium hydroxide at its Bitterfeld-Wolfen facility in Germany, the first of its kind in the EU. Vulcan, by contrast, is still in the construction phase. The€2.2bn financing is secured, but the company must now prove it can scale geothermal lithium extraction to 24,000 tonnes annually. The market’s scepticism, reflected in the stock’s persistent slide, will only lift once tangible production milestones are reached — and that wait may stretch into the Lionheart start-up itself.
