Spades in the Ground: Vulcan Energy Activates Lionheart Construction After €2.2 Billion Financing

Vulcan Energy shares shot up 6.5% to €2.39 on Friday, capping a week that saw the stock gain more than nine percent. Behind the move: a technical catalyst that traders rarely ignore. The relative strength index had plunged to 4.4 points, deep in oversold territory. With around five million shares changing hands in Frankfurt — well above the daily average — the buying pressure was unmistakable. The company’s annualised 30-day volatility of 67% explains why the rebound was so abrupt.

The trigger was the final closing of a €2.2 billion financing package for the Lionheart project in the Upper Rhine Valley. The deal, supported by a consortium of 13 lenders including European and German promotional banks as well as commercial banks, had been announced back in late 2025. This week’s news confirms that all conditions have been satisfied, unlocking the funds needed to build the first phase of the integrated lithium and renewable energy plant. The capital is structured across project, subsidiary and parent company levels, with disbursements tied to construction milestones.

Lionheart is designed to produce 24,000 tonnes of lithium hydroxide monohydrate annually — enough battery-grade material for roughly 500,000 electric vehicles. But the project is more than a lithium mine. Vulcan’s geothermal operations will generate 275 gigawatt-hours of electricity and 560 gigawatt-hours of heat each year, feeding local grids and district heating networks. The plant carries a 30-year design life, and the company’s proprietary VULSORB technology extracts lithium from geothermal brines, sidestepping the energy-intensive hard-rock mining typical of many competitors.

Should investors sell immediately? Or is it worth buying Vulcan Energy?

Construction is already under way on multiple fronts. Upstream, drilling work for production wells is proceeding near Landau. Downstream, the chemical processing plant that converts the lithium-rich brine into battery-grade lithium hydroxide is taking shape at the Industriepark Höchst in Frankfurt. First production remains on track for 2028. Chief financial officer Felicity Gooding called the financial close a “major milestone” during the annual general meeting on May 28 and stressed that the focus has now shifted squarely to meeting nameplate capacity and sticking to the budget throughout the build-out.

Analysts have greeted the financing news positively, pointing to the fully contracted offtake agreements and the strategic importance of domesticating Europe’s lithium supply chain. With the funding hurdle cleared, the project’s risk profile has changed fundamentally — from planning and permitting to delivery and execution.

Technically, however, the stock still faces headwinds. At €2.39, the shares are roughly 40% below the 52-week high of €3.98 and about 9% under the 200-day moving average of €2.60. The move off the lows at €1.80 — a 33% recovery so far — is for now driven by the oversold reading and the fundamental validation of the financing breakthrough. Whether the stock can sustain its momentum will depend on the next set of engineering milestones, including the expansion of the pipeline and grid connections that tie the upstream and downstream facilities together.

Vulcan’s management has laid out clear targets for the second half of this year. The planning phase is over. Now the task is to turn drawings and finance into concrete production capacity — and to prove that Europe’s largest lithium project can deliver on its promises.
