The Retrofit Revolution: How GreenFire Energy Is Turning Abandoned Oil & Geothermal Wells Into Continuous Clean Power Without New Drilling

The Retrofit Revolution: How GreenFire Energy Is Unlocking Geothermal Power Without Drilling a Single New Well By: Robert Buluma   While much of the geothermal energy sector has been focused on breakthrough drilling techniques—deeper wells, hotter reservoirs, and complex engineered systems—a quieter revolution has been unfolding in the background. Instead of chasing entirely new subsurface frontiers, one company has chosen a radically simpler question: What if the answer was already in the ground? GreenFire Energy is advancing a retrofit-first geothermal strategy that targets one of the most overlooked opportunities in the global energy transition: existing wells that are underperforming, depleted, or completely abandoned. Rather than drilling new holes into the Earth, the company is reusing the infrastructure that already exists—turning stranded assets into continuous sources of clean, baseload electricity. This approach is not just technically elegant. It may also be one of ...

Vulcan Energy Powers Ahead: Geox GmbH Acquisition Supercharges Lithium and Renewable Ambitions in Germany

In a move that promises to redefine the renewable energy and lithium landscape in Europe, Vulcan Energy has officially completed its acquisition of Geox GmbH  a bold stride toward streamlining operations and accelerating the energy transition. 



The deal, which includes geothermal wells, renewable energy generation assets, and a valuable geothermal and lithium licence around the City of Landau, Germany, positions Vulcan as a powerhouse in clean energy innovation.
Announced back in September 2024, the agreement aimed to consolidate Vulcan’s upstream Phase One lithium and renewable energy assets. By acquiring 100% of Geox’s holdings — and replacing a prior joint venture and brine offtake agreement — Vulcan has now secured total control of a strategic asset base that will serve as the cornerstone of its ambitious Lionheart Project.
Geothermal, Lithium, and Leadership
The assets at the heart of this acquisition are no ordinary infrastructure. Located in the Landau region — also home to Vulcan’s Lithium Extraction Optimisation Plant (LEOP) and the future Geothermal and Lithium Extraction Plant (G-LEP) — these wells will contribute to both lithium extraction and renewable heating solutions. Vulcan is set to dismantle the current Geox geothermal plant, enhance brine production from the licence area, and initiate local renewable energy supply through the upcoming G-LEP facility.
This move isn’t just about energy — it’s about scale. An estimated 20% of Phase One’s brine production will come from the newly acquired licence area, underlining its importance in the production of lithium battery chemicals for European partners and sustainable heating for German households.
€100 Million Confidence Boost
Vulcan’s visionary approach has not gone unnoticed. The German Federal Government has thrown its weight behind the renewable heating aspect of the project with a substantial €100 million grant — a vote of confidence in the project’s potential to provide green, baseload heating and reduce dependence on fossil fuels.
As initial supply to the City of Landau approaches, Vulcan is gearing up for construction and full-scale production — signaling a monumental shift not just for the company, but for the broader clean tech landscape in Europe.
CEO Cris Moreno’s Vision
Vulcan’s Managing Director and CEO, Cris Moreno, emphasized the significance of the acquisition, calling it “the final step in consolidating our upstream renewable energy assets for Phase One.” He noted that it streamlines operations and acts as a critical precursor to finalizing the project’s financing.
“We are at an important juncture in the history of Vulcan,” Moreno stated. “And we look forward to sharing more developments as we transition to the construction and production phase of the project.”
A New Energy Frontier
With the Geox GmbH acquisition complete, Vulcan Energy is not just expanding — it’s electrifying the path to a sustainable future. This strategic move reinforces its position as a leader in geothermal innovation and lithium production, making it a company to watch as Europe charges toward energy independence and climate goals.


Stay tuned. The geothermal revolution in Landau is just getting started.

Eavor steps back from operator role in the Geretsried geothermal project

Eavor at the Crossroads: What Geretsried Really Tells Us About the Future of Closed-Loop Geothermal By Alphaxioms Geothermal Insights | May 13, 2026 For years, Eavor Technologies was the geothermal sector's most talked-about enigma. The company raised hundreds of millions of dollars, attracted backing from heavyweights including BP , Chevron , Helmerich & Payne , and Temasek , and made bold promises about a proprietary closed-loop technology that would quietly revolutionise how humanity extracts heat from the earth. But it rarely said much in public. The secrecy was, to many observers in the geothermal community, a feature rather than a bug — protecting intellectual property, managing competitive intelligence, buying time. Now, Eavor is talking. And what it is saying is worth listening to very carefully. In an exclusive interview published on May 13, 2026, by GeoExpro editor Henk Kombrink, Eavor's new president and CEO Mark Fitzgerald — who took the role in October 2025 ...

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...

The XGS Energy Heat Sponge Solves Geothermal's Biggest Problem

The XGS Energy Heat Sponge Solves Geothermal's Biggest Problem I mage: A californian XGS well pad Imagine drilling a hole into the Earth’s hot crust  but instead of simply dropping in a pipe and hoping for the best, you paint the inside of that hole with a magic material that soaks up heat like a sponge soaks up water. Then you seal it, circulate a fluid, and generate clean, firm electricity  24/7, no fracking, no water consumption, no earthquakes. That’s not science fiction. That’s XGS Energy . While most of the geothermal world has been chasing fracked reservoirs or massive drilling rigs, XGS quietly built a prototype, ran it for over 3,000 hours in one of the harshest geothermal environments on Earth, and landed a 150 MW deal with Meta – enough to power tens of thousands of homes or a massive data center campus. This is the story of a technology that might be the most elegant, low-risk, and capital-efficient path to scalable geothermal power. Let’s dig in. Part 1: The Pro...

Fervo Energy Is Sitting on a Lithium Goldmine: Why DLE + IPO Is the Billion-Dollar Move They Haven't Made Yet

Fervo Energy has raised $1.5B, slashed drilling costs, and is eyeing an IPO. But ignoring DLE lithium co-production leaves billions on the table. Here's why By Alphaxioms | Energy & Critical Minerals Analysis Image: Fervo Energy’s Nasdaq debut marks a defining moment for geothermal energy. ⚡🌍 Fervo Energy has become the undisputed poster child of next-generation geothermal. With over $1.5 billion raised, drilling times slashed, and high-profile power deals with Google and California utilities, they've proven that enhanced geothermal systems (EGS) can work at scale  But Fervo is leaving money in the ground. Literally. Every day, Fervo pumps millions of gallons of hot, pressurized brine through deep underground fractures at Cape Station (Utah) and Project Red (Nevada). They extract the heat, generate clean electricity, and then reinject the fluid. Job done. Except that brine isn't just water. Across the Great Basin — where Fervo operates — geothermal brines carry d...
