Vulcan Energy's VULSORB Gamble: 95% Extraction Meets a Widening EUR 50.4 Million Hole
Published on 09/22/2026 at 16:21 | Editorial boerse-global.de
Vulcan Energy has handed investors a study in contrasts. On one side sits a genuinely novel industrial proposition — lithium pulled from the thermal brine beneath the Upper Rhine Valley, using a proprietary adsorbent cooked up in-house. On the other sits a balance sheet that keeps bleeding as the clock runs down toward first commercial output.
The market has made its verdict plain. The stock closed Tuesday at EUR 1.39 and has shed roughly 46% since the start of the year, with the shares changing hands around EUR 1.36 at points during the recent stretch. Skepticism, not enthusiasm, is the prevailing mood.
A Homegrown Answer to a Geopolitical Problem
The centerpiece of the company's technological story is VULSORB, an aluminate-based adsorbent designed to selectively pull lithium out of geothermal brine. Commercial manufacturing of the material has now begun, and in prior trials conducted under real-world conditions it delivered extraction rates of up to 95%, according to the company.
That number matters beyond the laboratory. China has long controlled the global market for direct lithium extraction technology and tightened export controls and licensing requirements early last year. By developing its own formulation and producing it through European partners, Vulcan aims to anchor a Western supply chain that does not run through Asia.
Chief executive Cris Moreno framed the production start as a de-risking milestone, saying it reduces the technology, supply chain and execution risks that hang over the project ahead of first regular output. The company also sees a second avenue through VULTEC, a unit set up to license the technology internationally on a selective basis, alongside supplying its own operations including the Ludwig project.
Should investors sell immediately? Or is it worth buying Vulcan Energy?
The first phase of the Lionheart venture, straddling the German-French border, is designed for annual capacity of 24,000 tonnes of lithium hydroxide monohydrate. The adsorbent will be loaded into the project's extraction columns ahead of the targeted start-up in the second half of 2028.
The Bill Comes Due Before the Revenue Does
Building industrial infrastructure of this scale means heavy spending long before a single tonne of battery-grade material is sold. The half-year report for the period ended June 30, 2026, published in September, laid that cost bare: the net loss ballooned to EUR 50.4 million, up sharply from a deficit of EUR 30.688 million in the same six months of 2025.
The full-year picture for 2025 is no gentler. Vulcan booked revenue of roughly EUR 7.35 million against a net loss of about EUR 69.58 million, with the commercialization of Lionheart the main driver of the outflow.
For investors, the arithmetic is straightforward. Until the plant is commissioned, pre-launch costs keep piling up while meaningful income stays out of reach — a capital-intensity problem familiar to anyone who has watched a geothermal and extraction project move from blueprint to steel. Staying inside the budget framework through to first production remains the yardstick by which the market will judge management.
Governance Shifts as the Build Phase Begins
The financial strain has been accompanied by changes at the top of the supervisory board. A mandatory disclosure showed Wedin holding 15,655,785 shares directly along with 40,600 performance rights, while Magni Associates Pty Ltd held 812,500 shares.
A leadership change at the head of a supervisory body often signals the handover from planning to execution. For the capital markets, though, any reshuffling at the top raises immediate questions about continuity and future governance. Whether the reconstituted board can keep tight rein on operational management and hold the schedule to account will go a long way toward determining investor confidence.
Permits in Hand, Patience Still Required
None of this reflects a project short on regulatory or technical progress. Lionheart holds a six-year extraction license from Rhineland-Palatinate's mining authority covering the Landau geothermal field, and the pieces on the technical and permitting side fit together.
What remains is the gap in time. With commissioning not slated until the second half of 2028, nearly two years of cash burn lie ahead, and the widening losses argue for sober expectations rather than optimism. The strategic case — a working technology base free of Asian dependence, a valuable card to play with future offtakers — is real. But until the industrial scale-up proves itself and the funding requirement stays manageable, operational risk is likely to keep the upper hand.
