Vulcan Energy’s Frankfurt Groundbreaking Marks the Start of a Costly Countdown

Vulcan Energy's €2.2B financing fuels lithium project construction, but investors eye accelerating cash burn ahead of Q1 results on April 29.

The champagne has barely dried on Vulcan Energy’s €2.2 billion financing package, but investors are already bracing for the hangover. When the lithium developer publishes its first-quarter results on April 29, the spotlight will fall squarely on one metric: how fast the cash is draining.

The ceremonial spade hit the ground in Frankfurt this month, with Hesse’s premier minister Boris Rhein and Frankfurt’s mayor Mike Josef looking on. The scene at Industriepark Höchst was part celebration, part political statement — Germany is betting heavily on domestic lithium production, and the European Union has now designated the Lionheart project as strategic under the Critical Raw Materials Act.

But the real work has already begun. Drilling is running simultaneously at the Schleidberg and Trappelberg sites, and the central lithium chemical plant in Frankfurt is now under construction. That plant will process lithium chloride solution extracted in Landau into battery-grade lithium hydroxide monohydrate, using Vulcan’s proprietary VULSORB® technology, which the company claims extracts lithium from geothermal brines with over 90% efficiency.

Phase one targets an annual capacity of 24,000 tonnes, with commercial production slated for 2028 — two and a half years from now. Alongside lithium, the facility will generate 275 gigawatt-hours of renewable electricity and 560 gigawatt-hours of heat each year for local users.

The Cash Question

Vulcan ended December with €523 million in the bank. In the previous quarter, operating costs ran at €7.2 million. That figure is about to surge. With the main drilling program ramping up in the second half of 2026 and construction now underway at multiple sites, the burn rate is accelerating.

A small relief came from the state of Rhineland-Palatinate, which exempted Vulcan from extraction levies through the end of 2030. But that will only go so far. The company’s financing backbone is solid — a banking consortium has committed nearly €1.2 billion in senior loans, supplemented by €204 million in government grants and Hesse’s €13.9 million subsidy — yet the market is watching execution closely.

The share price has rallied roughly 38% over the past 30 days to $2.70, but that still leaves it about 32% below the 52-week high of $3.98. The recovery reflects optimism around the financing package, but the real test begins now.

Supply Chain Takes Shape

On the supplier side, Vulcan has been locking in partners. Siemens signed a €40 million deal for automation and building technology, with preferred-partner status extending to 2035. French materials specialist Mersen inked a multi-million-euro contract to supply an Eco&FLEX® unit that supports the conversion of lithium chloride and enables chlorine recovery from the process.

Offtake agreements with Umicore, LG Energy Solution, Stellantis and Glencore already cover roughly 72% of planned production for the first decade.

Boardroom Changes and Missed Targets

To strengthen oversight during the construction phase, Vulcan added Roberto Gallardo to its board in early April. Gallardo is the strategy chief at Hochtief, the construction giant that took a major stake in Vulcan last December, and brings deep infrastructure expertise.

But internal discipline appears to be tightening. In March, more than 400,000 performance rights for management — including shares held by CEO Cris Moreno — lapsed after certain operational milestones were missed. The message is clear: the company is holding itself to a strict standard.

The annual general meeting on May 28 will require management to defend the Lionheart project’s cost framework in detail. The first-quarter report arriving next week will provide the first hard data to judge whether the build phase is on track — or whether the cash is burning faster than planned.
