Vulcan Energy's Lionheart Blueprint: Two Licences, a New Chairman, and a EUR 1.26 Billion Second Act
Published on 09/23/2026 at 20:00 | Editorial boerse-global.de
Technical breakthroughs in the raw materials sector offer no guarantee of a warm reception on capital markets, and Vulcan Energy is proving the point. The Frankfurt-listed developer is pressing ahead with plans to extract lithium and geothermal heat in the Upper Rhine Valley, yet its share price tells a far less optimistic story.
Since the start of the year, the stock has shed 47 percent and now trades at EUR 1.36. Even a steady drumbeat of operational milestones — fresh permits, in-house material production, a completed feasibility study — has done little to shift the mood.
VULSORB and the Push for a China-Free Supply Chain
At the heart of Lionheart, the company's first development phase, sits a proprietary extraction technology. Vulcan has begun commercial production of its own adsorbent, VULSORB, a move designed to sever reliance on suppliers outside Europe. The material is covered by Western intellectual property rights and sourced through a European supply chain. According to the company, the process achieves lithium extraction efficiency of up to 95 percent.
The end product is battery-grade lithium hydroxide monohydrate. While the technology forms an essential building block for Lionheart's timeline, the wait for commercial operation remains long: commissioning is pencilled in for the second half of 2028.
Regulatory groundwork has advanced in parallel. Vulcan holds the Ilka lithium extraction licence for the project, valid for six years, following the earlier award of the LiThermEx permit. Ilka was granted roughly two weeks ago — a period in which the shares have slipped 8.8 percent.
Should investors sell immediately? Or is it worth buying Vulcan Energy?
Ludwig: A Cheaper Second Phase, but a Hefty Price Tag
Management is already preparing the next step. A feasibility study released about two weeks ago for the follow-up Ludwig project near Ludwigshafen puts the scale of phase two into numbers. Development capital is estimated at EUR 1.26 billion, based on real 2026 costs and including a 15 percent contingency buffer. Measured against comparable lithium carbonate equivalent capacity, that figure sits roughly 15 percent below the projected cost of Lionheart.
The study also sketches out the economics over a 30-year operating life: a pre-tax net present value of EUR 2.6 billion and an internal rate of return of 25 percent. Since the preliminary study was announced, the stock has given up 17.4 percent.
Those lower unit costs hint at economies of scale down the road, but the sheer size of the capital requirement looms large against a market capitalisation of EUR 659.28 million. How the company intends to fund the build-out is now a central question for investors.
A New Chair, and a Founder Steps Back
Leadership has been reshuffled as well. Just over a week ago, Angus Barker took over as Non-Executive Chair, having previously served as Lead Independent Director and deputy chair. Company founder Dr. Francis Wedin simultaneously moved from Executive Chair into an advisory role. The stock has lost 4.7 percent since that reorganisation.
Scepticism on the exchange continues to reflect the enormous capital needed to bring the deep geothermal and extraction facilities to life. Trading 34 percent below its 200-day moving average of EUR 2.07, the broader trend on the German market remains firmly downward.
For management, the coming months will hinge on one thing: proving in practice that the projected cost advantages and the schedule running to a 2028 production start can actually be delivered. Until the Upper Rhine sites begin commercially supplying lithium and geothermal energy, investors will need staying power — and the decisive test of whether the large-scale plants can be operated economically and financed in full is still some years away.
