🚀 Margün Energy Enters the Lithium Game

Margün Energy, a Turkish renewables company, has announced plans to explore lithium extraction from geothermal brine at its newly acquired 12 MW geothermal facility in Kavakdere, Seferihisar. The site lies within a vast 3,125-hectare exploration concession in İzmir that the company intends to analyze for lithium mineral content and other valuable elements.

While Margün Energy clarified that it is not a mining company and has not applied for mining licenses, it emphasized that direct extraction from geothermal fluid is fundamentally different from conventional mining. If sufficient lithium concentrations are confirmed, Margün plans to build an on-site extraction plant integrated with its geothermal operations.

🌞 Hybrid Power Boost

In tandem with its geothermal initiative, Margün is pursuing a hybrid model. A 5.4 MW photovoltaic (solar) unit has been proposed to be added to the existing geothermal plant. This is expected to produce around 10 GWh annually, potentially increasing annual revenues by over a million dollars. Once complete, Margün’s total installed capacity will reach 135.4 MW, spanning hydropower, wind, solar, and geothermal energy through its affiliate, Enda Energy Holding.

🔋 Turkey’s Geothermal Mineral Vision

Turkey already ranks among the global leaders in geothermal energy, with 65 operational plants contributing around 1.74 GW to the national grid. Yet, the country is only utilizing an estimated 10% of its full geothermal potential. Over 1,000 wells across the nation generate approximately 100,000 tons of brine per hour, containing lithium in concentrations of about 20 parts per million.

With these figures, it's estimated that lithium extraction from geothermal brine could yield up to 35,000 tons annually—more than enough to cover Turkey’s domestic demand and position the country as a significant global player in lithium production.

⚙️ Tech Innovation & Strategic Synergy

Extracting lithium alongside geothermal energy production offers a dual-revenue model—electricity and battery-grade materials—with minimal additional environmental impact. Compared to conventional mining, direct lithium extraction bypasses the need for evaporation ponds and reduces land and water disruption.

This strategy aligns with broader energy and industrial transitions happening in countries pursuing net-zero goals, where geothermal resources are being reimagined as not only a source of clean power but also a reservoir for critical minerals.

🌱 Economic & Environmental Upside

Integrating lithium recovery into geothermal operations can dramatically improve the economics of such projects, reducing payback periods and unlocking additional value from existing infrastructure. The extracted lithium comes from brine already being pumped for energy, which means no new environmental disturbance is necessary.

This approach also supports Turkey’s ambitions for building domestic EV battery supply chains, complementing its robust auto manufacturing industry. Experts estimate that Turkey’s geothermal lithium reserves could supply domestic lithium needs for decades while generating billions in export revenue.

⚠️ Challenges & Local Sentiment

Despite the promise, local residents in Seferihisar have raised environmental concerns. While the project differs fundamentally from traditional mining operations, public awareness and community engagement will be key to maintaining support.

One technical challenge is the relatively low concentration of lithium in geothermal brine. Effective and sustainable extraction will depend on the development and deployment of advanced, low-impact technologies for direct lithium extraction.

🧭 What’s Next?

Margün Energy plans to proceed with field testing and sampling to determine the economic viability of lithium extraction. If the results are favorable, a pilot extraction plant may be constructed as part of the existing geothermal infrastructure.

At the national level, Turkey is working toward increasing its geothermal capacity to 3 GW by 2030, backed by a combination of international financing and domestic investment. Lithium extraction from geothermal brine may become a powerful catalyst for reaching that goal while contributing to the global clean energy supply chain.

✅ Conclusion

Margün Energy’s bold move signals a new frontier in clean energy. By transforming geothermal sites into dual-purpose assets—delivering both renewable power and strategic minerals—the company is helping redefine what’s possible in the energy transition.

This is more than geothermal. It’s geothermal with purpose, powering the future from the deep earth below.

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. While the well has since been contained and no injur...

Enhanced Geothermal Systems Financing Hurdles

The Heat Beneath: Why Enhanced Geothermal Systems Can't Get Financing—And What It Will Take to Change That By : Robert Buluma Introduction: The Paradox of Boundless Energy Beneath our feet lies an energy source so vast that capturing just a fraction of it could power civilization for millennia. More than five terawatts of heat resources exist beneath the United States alone—enough to meet the electricity needs of the entire world. Enhanced Geothermal Systems (EGS), which circulate water through engineered fractures in deep hot rock, promise to unlock this resource nearly anywhere on the planet, not just in volcanic hotspots. The technology is improving faster than almost anyone expected. Costs are falling. The fossil fuel industry's drilling expertise is being repurposed. And yet, for all its promise, EGS remains stuck in a financial no-man's-land—too big for venture capital, too risky for traditional lenders, and too unfamiliar for the infrastructure investors who could tr...

Rodatherm Energy: The Refrigerant Gambit

By: Robert Buluma Rodatherm Energy has done something no other geothermal startup has attempted at commercial scale: swapped water for refrigerant in a closed-loop system. The claim is 50% higher thermal efficiency than water-based binary cycles, achieved by circulating a proprietary phase-change fluid through a fully cased, pressurized wellbore. The company emerged from stealth in September 2025 with a $38 million Series A—the largest first venture raise in geothermal history. Lead investor Evok Innovations was joined by Toyota Ventures, TDK Ventures, and the Grantham Foundation. The engineering thesis is elegant. The execution risks are significant. This is an Alphaxioms examination of both. II. The Thermodynamic Distinction Every geothermal company you've covered moves heat using water or steam. Rodatherm moves heat using a fluid that boils and condenses inside the wellbore. In a conventional closed-loop water system (Eavor's model), water circulates as a single-phase liq...
