Vulcan Energy: Drilling Depth and Electrolysis Deployment Set the Stage for Lionheart's Make-or-Break Financing

Vulcan Energy completes Lionheart well LSC-2 and installs electrolysis, but share price slides 12% as €2.2B financing closure remains key for 2028 lithium output.

The Lionheart project in Germany’s Upper Rhine Graben has reached another operational milestone: the sixth well, LSC-2, has touched its target depth of 3,000 metres. That follows LSC-1, which delivered flow rates of 105 to 125 litres per second — precisely the kind of data required to underpin the twin revenue model of geothermal energy and lithium extraction from brine. Completion work and flow tests are slated for the second quarter of 2026.

On the surface, a separate but equally critical piece of the puzzle is falling into place. Vulcan has begun installing proprietary electrolysis systems from NORAM Electrolysis Systems at the Industriepark Höchst in Frankfurt. This marks the first large-scale commercial deployment of NORAM’s technology in the global battery supply chain. The unit will convert lithium chloride into battery-grade lithium hydroxide monohydrate, forming the second stage of the production chain after the lithium-rich brine is extracted from deep geothermal reservoirs. The initial phase of Lionheart targets 24,000 tonnes of lithium hydroxide per year, with commercial production pencilled in for 2028.

Yet none of that progress is being reflected in the share price, which closed recently at €2.30, down nearly 12% year-to-date and more than 40% below its 52-week high. The market’s caution stems from one overarching uncertainty: the formal closing of Lionheart’s €2.2 billion financing package.

That package, assembled in December 2025, comprises a €1.2 billion senior debt facility and roughly €204 million in government grants, backed by 13 institutions including the European Investment Bank and several European export credit agencies. The formal close is expected in the second quarter of 2026 and would unlock the bulk of the funding. Without it, the construction timetable remains tight.

In the meantime, expenditure is already ramping up. Vulcan burned €76 million in operating cash during the first quarter and spent nearly €140 million on specialty equipment and new drilling, largely at the Schleidberg site and Frankfurt. End-of-quarter liquidity stood at €364.3 million, of which €117 million was held in short-term deposits — a meaningful buffer, but one that replaces neither the scale nor the certainty of the stalled financing.

Support from the commodity market is strengthening. Battery-grade lithium carbonate has jumped around 50% since the start of the year to roughly $25,600 per tonne, with European battery-quality grades hovering near $20,500. BMI, a subsidiary of Fitch Solutions, recently raised its 2026 price forecast, citing surging demand from electric vehicles and the rapid expansion of energy storage for data centres.

That tailwind matters for Vulcan because 72% of its contracted volumes carry fixed prices or price floors. The largest single offtake agreement is with Stellantis for 128,000 tonnes of lithium hydroxide over ten years. Further contracts with LG Energy Solution (31,000 tonnes) and Glencore (up to 44,000 tonnes) also include downside protection, as does an agreement with Umicore.

With the offtake side largely secured and drilling progressing, the investment case hinges on the closing of the financing. The disconnect between operational momentum and equity valuation is stark: the price-to-book ratio sits at just 1.2, against an industry average of 5.8. Canaccord Genuity has reiterated a buy recommendation, setting a price target of €4.45 for the Frankfurt-listed shares — implying roughly 91% upside — and for the London-listed paper lifted its target from 287p to 323p. The Australian-listed equivalent carries a target of A$10.75.

The next catalyst arrives on 28 May, when Vulcan holds its annual general meeting in Perth. Chief executive Cris Moreno will have the floor to clarify the financing timeline and the upcoming drilling campaign. Shareholders will also vote on board changes, including the election of Roberto Gallardo, a strategist from Hochtief who led a €169 million investment in Vulcan last December for a 15.4% stake.

In a sign that internal targets have been missed, two tranches of performance rights have lapsed — 79,297 in May, following 413,811 in March — reducing potential dilution but underscoring the pressure on management to deliver the next step.

Operationally, Vulcan is moving from exploration into construction. The drilling campaign continues with 24 production and reinjection wells planned in phase one, and a second rig is expected to join in the second half of 2026. At Schleidberg, subsidiary VERCANA is preparing the site, with Expro Group Holdings contracted to provide testing services for the first well. Meanwhile the Frankfurt plant is taking shape.

What remains is the signature that turns a series of milestones into a funded, de-risked project. That signature is now the single most important factor for the stock.
