Eavor Demobilizes Rigs from Geretsried: What It Really Means for Closed-Loop Geothermal For three years, two drilling rigs on a farm estate near Geretsried, a Bavarian town about 40 km south of Munich, stood as the symbol of the world's most ambitious closed-loop geothermal experiment. Now in October 2026, Eavor Technologies, the Calgary-based developer of the Eavor-Loop, has told the town and its heating utility that both rigs would leave the site . The company said keeping idle rigs and specialist services on site was costly, and that releasing them would help put the project in the strongest position to continue with Loop 2 once its commercial structure is reworked . On the surface, this is a logistics decision. Underneath, it is one of the clearest signals yet about where first-of-a-kind geothermal technology stands, and how hard it is to turn a technical proof into a bankable business. This article explains exactly what happened, what the move means and what it does not mean...
T5 Smackover Partners and Glencore Deal: A Turning Point for Geothermal Lithium in East Texas
By: Robert Buluma
A quiet but powerful shift is unfolding in the global energy landscape. For decades, geothermal energy has been discussed almost exclusively as a clean electricity source. But in 2026, that definition is rapidly expanding.
The latest signal comes from East Texas, where T5 Smackover Partners has signed a binding offtake agreement with global commodities giant Glencore for lithium carbonate production from the Smackover Formation.
On the surface, it looks like another lithium deal in a crowded critical minerals market. But underneath, it represents something far more significant: the merging of geothermal energy systems with large-scale mineral extraction, particularly lithium, at an industrial scale.
This is not just about batteries. It is about energy systems becoming mineral systems—and mineral systems becoming energy systems.
The Core Deal: What Was Actually Signed?
At the center of the announcement is a structured offtake agreement:
- Glencore will purchase and market 100% of Phase 1 lithium production
- Estimated output: ~5,000 metric tons of lithium carbonate per year
- Contract duration: 5 years
- Total volume: ~25,000 metric tons over the contract term
- Deliveries begin at first commercial production
- Lithium will be produced via Direct Lithium Extraction (DLE)
- Production is integrated with geothermal energy operations in East Texas
This is not a speculative memorandum or a soft partnership. It is a binding commercial arrangement that effectively locks in early-stage production for a globally recognized commodities trader.
In the lithium industry, offtake agreements are often the bridge between resource development and financial bankability. Without them, projects struggle to secure financing. With them, projects begin to transition from geological potential to industrial reality.
The Smackover Formation: America’s Hidden Subsurface Giant
To understand why this deal matters, you have to understand the geology behind it.
The Smackover Formation is a deep subsurface geological formation that stretches across parts of the southern United States, including East Texas. Historically, it has been known for oil and brine production. But beneath that legacy lies a modern opportunity: lithium-rich brines.
These brines are not solid rock deposits. Instead, they are underground saltwater reservoirs containing dissolved minerals, including lithium. When extracted and processed, they can produce battery-grade lithium carbonate.
What makes Smackover especially important is its dual-use potential:
- It is geothermally active in certain zones
- It contains lithium-bearing brines
- It supports subsurface fluid circulation systems
This combination creates a rare opportunity: co-production of geothermal energy and lithium from the same reservoir system.
In simpler terms, the same underground system that can generate heat for electricity can also supply critical minerals for batteries.
Direct Lithium Extraction (DLE): The Technology Behind the Deal
The real technological backbone of this project is Direct Lithium Extraction (DLE).
Traditional lithium production relies heavily on:
- Hard rock mining (spodumene)
- Evaporation ponds (brine concentration)
Both methods are land-intensive, slow, and environmentally disruptive.
DLE changes that equation.
Instead of evaporating large surface ponds or mining rock, DLE:
- Extracts lithium directly from brine
- Uses selective adsorption or membrane technologies
- Re-injects processed brine back underground
- Operates in a closed-loop system
This is where geothermal integration becomes critical.
In geothermal systems, brine is already being pumped, processed, and re-injected to extract heat. By layering DLE into that same system, lithium becomes a byproduct of energy production rather than a standalone mining operation.
This is one of the most important conceptual shifts in modern resource development:
Energy wells are becoming mineral wells.
Why the Glencore Offtake Matters
Glencore is not a startup speculator. It is one of the world’s largest diversified commodity trading and mining companies, with deep involvement in metals, energy, and industrial supply chains.
Its participation signals three major things:
1. Market Validation
If a global commodity trader is willing to lock in 5,000 tons per year, it suggests confidence in:
- Resource quality
- Processing capability
- Commercial scalability
2. Supply Chain Integration
Glencore sits at the center of global material flows. That means East Texas lithium is not staying local—it is entering global battery and industrial markets.
3. Bankability Signal
Offtake agreements like this are often used by financiers to de-risk projects. This deal increases the likelihood of future expansion phases being financed.
In essence, Glencore is acting as both a buyer and a credibility amplifier.
The Bigger Picture: Lithium Demand Is Not Slowing Down
The timing of this deal is not accidental. Global lithium demand continues to accelerate due to:
- Electric vehicle expansion
- Grid-scale battery storage
- AI data center energy needs
- Defense and aerospace electrification
- Industrial decarbonization policies
Even with new supply coming online globally, the market remains tight for battery-grade lithium carbonate.
The United States, in particular, faces a strategic challenge: it consumes large volumes of lithium but remains heavily dependent on imports.
That dependency has turned lithium into a national security concern.
This is where the Smackover Formation becomes strategically important.
Geothermal + Lithium: The Emerging Hybrid Industry
What makes this project especially significant is not just lithium production—it is the hybrid model.
Traditionally:
- Geothermal = electricity
- Mining = minerals
Now:
- Geothermal = electricity + minerals
This hybrid approach changes the economics entirely.
A geothermal plant that once relied solely on electricity revenue can now generate multiple income streams:
- Power sales
- Lithium production
- Mineral byproducts (potentially including other critical elements)
This diversification can:
- Improve project viability
- Reduce risk exposure
- Increase capital efficiency
In many ways, geothermal energy is evolving from a single-output system into a multi-output resource platform.
East Texas as a Strategic Energy-Minerals Hub
The announcement also positions East Texas as more than just a regional energy producer. It suggests a broader industrial transformation.
If scaled successfully, the region could become:
- A geothermal energy hub
- A domestic lithium production center
- A critical minerals supply node
- A manufacturing feedstock zone for batteries
This aligns with broader U.S. policy goals around reshoring supply chains for:
- EV batteries
- Grid storage systems
- Defense manufacturing
- Semiconductor-related materials
What makes East Texas particularly attractive is its combination of:
- Existing oil and gas infrastructure
- Skilled subsurface engineering workforce
- Geological formations suitable for brine extraction
- Proximity to industrial Gulf Coast corridors
Economic Implications for Local Communities
One of the most interesting elements of the announcement is the emphasis on landowners and local participation.
The company highlights that:
- Royalty structures will benefit landowners
- Local communities are central to project development
- Value is intended to remain within East Texas
If implemented effectively, this could represent a shift from extractive legacy industries to more distributed benefit models.
Historically, resource development in regions like East Texas has followed a boom-and-bust oil cycle. A geothermal-lithium hybrid model could introduce longer-term stability by diversifying revenue streams and reducing dependence on fossil fuel price cycles.
Challenges Ahead: Not a Guaranteed Success Story
Despite the optimism, several challenges remain:
1. Scaling DLE Technology
DLE is still transitioning from pilot to full industrial scale. Efficiency, cost, and recovery rates will determine long-term viability.
2. Reservoir Management
Co-producing geothermal energy and lithium requires careful management of:
- Fluid chemistry
- Pressure balance
- Reinjection strategies
3. Capital Intensity
Even with offtake agreements, large-scale subsurface projects require significant upfront investment.
4. Regulatory Complexity
Mining, energy production, and water rights regulations overlap, creating a complex permitting environment.
Why This Deal Matters Globally
This is not just a U.S. story. It reflects a global trend:
- Chile is modernizing brine extraction
- Europe is exploring geothermal lithium pilots
- Australia is scaling hard rock production
- China continues to dominate refining capacity
But the Smackover model introduces something different: integration.
Instead of separating energy and mineral systems, it merges them.
If successful, this model could be replicated in other geothermal-rich sedimentary basins worldwide.
Final Thoughts: A New Category of Resource Development
The T5 Smackover–Glencore agreement is more than a commercial contract. It is a signal of where the resource industry is heading.
We are entering a phase where:
- Subsurface systems are multi-purpose
- Energy production and mineral extraction converge
- Geology becomes a platform for industrial ecosystems
East Texas is now part of a global experiment in redefining what “energy infrastructure” actually means.
If geothermal was once about heat beneath the Earth, it is now about everything that heat can unlock.
And in that shift, lithium is just the beginning.
