From Brine to Batteries: Vulcan’s Landau Breakthrough in Geothermal Lithium

Vulcan Energy secures land in Landau for its geothermal + lithium plant a major leap toward Europe’s carbon-neutral lithium for EVs ⚡

By:Robert Buluma

Vulcan Energy just cleared a big hurdle in its plan to create a homegrown, low-carbon battery supply chain for Europe. The company has secured approval to purchase the plot in Landau (Rhineland-Palatinate) for a combined Geothermal and Lithium Extraction Plant (G-LEP) — the physical site where geothermal heat and lithium will be produced side-by-side.

What happened (short version)

On 11 September 2025 Vulcan announced it has secured approval from the City of Landau council to purchase the D12 industrial plot where it will build its G-LEP.

This follows an earlier option agreement between the company and the city that had already reserved the site for Vulcan.

Why this matters — more than just land

Vulcan's model is unique: it uses geothermal brine (hot, lithium-bearing fluid underground) to produce both renewable heat/electricity and to extract lithium via water-based chemical processing. That allows lithium chemicals to be made with very low lifecycle CO₂ compared with conventional mined and processed lithium — a critical selling point for automakers chasing truly low-carbon EV supply chains.

The Landau G-LEP will be one of the physical anchors of that vision: local heat and electricity generation (reported building permits include a 30 MW geothermal plant and associated electrical substation) plus lithium extraction infrastructure. That tight integration is what enables the company to claim a path to carbon-neutral or near-zero carbon lithium.

Financing & policy tailwinds

Vulcan has also attracted substantial public support: the company secured €104 million in German government grants for its “Clean Lithium for Battery Cell Production” program earlier in 2025, part of a coordinated push by Berlin to strengthen Europe’s raw-materials sovereignty for batteries. That funding — paired with EU strategic project recognition — gives the Landau plan stronger chances of timely build-out.

What this means for Europe’s EV supply chain

Reduced import dependence — Producing lithium inside the EU reduces exposure to long overseas supply chains and the emissions associated with them.

Cleaner batteries — Lithium produced with geothermal energy can materially cut the carbon footprint of battery cells and therefore of EVs made with those cells.

Industrial clustering — A Landau G-LEP creates local jobs, downstream chemical conversion activity (e.g., to lithium hydroxide), and strengthens links with European automakers that are already signing offtake/partnership agreements with Vulcan.

Risks & open questions

No project is risk-free. Key items to watch:

Permitting & community acceptance: geothermal and DLE projects still require robust community engagement and environmental permitting (noise, traffic, subsurface risks). The Landau council approval to sell the land is a big step, but further permits and construction approvals remain.

Scale-up & processing: piloting and small-scale production are different from industrial throughput — Vulcan must demonstrate consistent product quality at commercial volumes.

Financing execution: public grants help, but large industrial plants need more capital (debt/equity/partners). Vulcan has been pursuing a multi-source financing package.

Bottom line

The Landau land approval is a concrete, high-visibility step from concept to construction for Vulcan's vision of Europe’s first integrated, low-carbon lithium supply sourced from local geothermal brines. If the company can navigate permitting, scale-up, and financing, Landau could become a blueprint for how regions produce battery materials with a dramatically smaller carbon footprint — an important piece in the puzzle of genuinely green electric mobility.

Green Therma Selects H&P to Drill Denmark’s Longest Geothermal Well

Green Therma Selects H&P to Drill Denmark’s Longest Geothermal Well for Aalborg Heat4Ever Demonstration Denmark is moving from geothermal ambition to execution. Green Therma has selected Helmerich & Payne to drill the Heat4Ever demonstration well near Aalborg, a project that could become one of the country’s most technically ambitious geothermal developments and a meaningful test of closed-loop district heating. A milestone for Danish geothermal The Aalborg Heat4Ever project matters because it is designed to prove that geothermal heat can be delivered without relying on a natural hot-water reservoir. Instead of producing groundwater from a conventional geothermal field, the system uses a closed-loop pipe-in-pipe design that circulates the same fluid downhole, heats it in contact with hot rock, and returns it to the surface for district heating use. That distinction is important for Denmark, where district heating is already a major part of the energy system ...

Blowout at Cape Station: Fervo Energy’s First Major Crisis After Blockbuster IPO

Just weeks after a record-breaking IPO, the flagship project of the "geothermal unicorn" faces its first major operational crisis. By : Robert Buluma Beaver County, Utah – The morning of May 27, 2026, began like any other at the Cape Station construction site in rural Utah. Workers for Fervo Energy, the newly public darling of the renewable energy world, were engaged in the complex task of drilling deep into the Earth’s crust to unlock what the company promised would be the future of 24/7 clean power. But by the afternoon, the routine had turned into a crisis. The site had experienced a blowout—an uncontrolled release of fluid or pressure from a well. For any energy company, a blowout is a serious matter. For Fervo Energy, which had just raised $1.89 billion in a blockbuster Nasdaq debut two weeks prior, it represents an immediate stress test of its technology, its safety protocols, and its $7.7 billion market valuation.
