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

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

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
  1. Reduced import dependence — Producing lithium inside the EU reduces exposure to long overseas supply chains and the emissions associated with them.
  1. Cleaner batteries — Lithium produced with geothermal energy can materially cut the carbon footprint of battery cells and therefore of EVs made with those cells.
  1. 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.

Exergy Gemini Turbine vs Ormat Ormega100: Geothermal Binary Power Comparison

By Robert Buluma Alphaxioms
Exergy Gemini Turbine vs Ormat Ormega100: Two Different Paths to Geothermal Scale image : a thematic view of a geothermal turbine "blade" Geothermal power is entering a new phase. Two of the most important announcements in the sector point to larger, more standardized, and more commercially viable binary geothermal systems: Exergy’s Gemini Turbine and Ormat’s Ormega100 . At first glance, both machines promise major gains in scale, but they are not trying to solve the same problem in exactly the same way. Gemini is built around a high-capacity radial outflow turbine architecture that can deliver up to 60 MWe per shaft, while Ormega100 is designed as a 100 MW binary surface power unit intended to accelerate enhanced geothermal system commercialization. For project developers, utilities, and data-center buyers looking for firm clean power, the comparison matters because it reveals two competing ideas about how geothermal should grow. Exergy is emphasizing turbine architectur...

GA Drilling: Advanced Geothermal Drilling Technology, Deep Rock Innovation, and Clean Energy Financing

By Robert Buluma Alphaxioms
GA Drilling : Deep Drilling Technology, Financing, and Geothermal Scale-Up Image: A GA Drilling Bit GA Drilling is one of the more important technology companies in the geothermal sector because it is trying to solve a problem that has limited geothermal growth for decades: the cost, complexity, and risk of drilling deep wells in hard rock. Rather than operating a geothermal power plant itself, the company focuses on the drilling side of the value chain, developing technologies that can make deep geothermal wells faster, cheaper, and more reliable to build. That positioning gives it a different role from most geothermal developers, and it also makes it strategically significant for the future of clean baseload energy. The geothermal industry has always been constrained by subsurface uncertainty. Developers know where the heat is in a general sense, but they still must drill through high-temperature, abrasive, fractured, and often unpredictable rock to get there. In many projects, dril...

EGS Market Size and Investment Outlook

By Robert Buluma Alphaxioms
Enhanced Geothermal Systems (EGS) Market Size and Investment Outlook to 2034 Enhanced Geothermal Systems are at an inflection point. For years, EGS sat in the “promising but pre‑commercial” category of clean technologies, constrained by drilling cost, subsurface risk, and limited policy attention. That picture is now changing as next‑generation geothermal developers raise larger rounds, sign serious offtake agreements, and move projects from concept to execution.   At the same time, global demand for firm, low‑carbon power is rising faster than conventional geothermal can supply. Thermal plants are retiring, grids need 24/7 clean electricity, and policymakers are discovering that weather‑dependent renewables cannot carry the entire load alone. EGS is emerging as one of the few technologies capable of delivering baseload clean power using a resource available almost everywhere: deep, hot rock. Current EGS Market Size – Small but Strategic In absolute terms, the EGS market is s...

Tarragona Geothermal Energy Project: Renewable Heating Potential in Six Municipalities

By Robert Buluma Alphaxioms
Hidden geothermal energy under six Tarragona municipalities could power a new phase of the energy transition Image : A Geothermal Power Plant gushing steam to power a grid   A renewable resource beneath the ground A new study in Tarragona has revealed that geothermal energy could become a major local source of heat and cooling for six municipalities: Ascó, Mont-roig del Camp, Montbrió del Camp, Flix, Ulldemolins, and El Perelló . The research suggests that shallow geothermal systems could supply hundreds of buildings and public facilities with a steady, renewable, and locally available energy source . The idea is compelling because it combines climate action with territorial resilience. Instead of depending entirely on imported energy or weather-dependent renewables, these towns could tap into the stable temperature of the subsoil to produce heating, cooling, and domestic hot water . For a region that is already managing the transition away from nuclear dependence, this could ...

California Invests in Geothermal Exploratory Wells, Unlocking Next‑Generation Geothermal Growth, Clean Firm Power, and Investment Opportunities in California Geothermal Funding

By Robert Buluma Alphaxioms
California’s Big Bet on Next,Generation Geothermal, Why New State Funding Could Unlock Clean, Firm Power California just took an important step toward scaling next,generation geothermal energy. In the 2026 budget, Governor Gavin Newsom and the state legislature included targeted funds for geothermal exploratory wells and early,stage in,field programs, a move Clean Air Task Force (CATF) says is essential to overcoming the subsurface uncertainty that has slowed project deployment. This funding mirrors recommendations from CATF’s recent report, “Build Here: How Targeted State Investment in Geothermal Can Fill California’s Clean Firm Gap,” and could accelerate geothermal’s role as a reliable complement to wind, solar, and storage. Below I unpack why the new funding matters, how it addresses the industry’s biggest barriers, what the potential economic and grid benefits are, and where private capital, developers, and policymakers should focus next to turn this promise into projects.

Colombia Grants El Barranquero Geothermal Exploration Permit, Advancing Policy, Investment, and Renewable Energy Growth

By Robert Buluma Alphaxioms
Colombia Grants Geothermal Exploration Permit to El Barranquero Project A New Signal for Colombia’s Geothermal Future Colombia has taken another decisive step in geothermal energy by granting an exploration permit for the El Barranquero project, a move that strengthens the country’s push to diversify its clean energy mix. The permit is more than a routine approval; it shows that geothermal is moving from policy ambition to practical development in a market that has long talked about its potential but struggled to unlock it.  The project sits between Samaná in Caldas and Nariño in Antioquia, placing it in one of the areas identified for geothermal development by Colombia’s geological authorities. That geographic detail matters because geothermal projects depend heavily on site quality, underground heat, and long-term regulatory certainty.  What the Permit Covers The Ministry of Mines and Energy granted the permit for five years, giving the developers time to carry out a full ex...

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

By Robert Buluma Alphaxioms
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. While the well has since been contained and no injur...
