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 ...

This project is part of the larger PUSH-IT initiative, which is funded by the European Union.


2. Data Collection through Exploratory Wells:


The exploratory wells play a pivotal role in understanding the geological characteristics of the area. Measurements taken from these wells will determine the groundwater abundance and flow direction. Additionally, data on system parameters, such as well depth and number, will be crucial for optimizing the efficiency of the geothermal energy storage and collection system.


3. Core Sampling for Thermal Capacity:


Approximately 500 meters of core will be extracted from the deeper well, providing insights into the total thermal capacity available for storage within the system. This information is vital for assessing the potential of Litomerice's geothermal reservoirs to serve as a sustainable heat source.


4. Monitoring Network Expansion:


To ensure the safe and efficient operation of the geothermal facility, a robust monitoring network will be established. This network will extend beyond the exploratory wells to include additional wells positioned around the well field. Combined with the existing seismic network, this comprehensive monitoring system will serve as both a safety measure and a valuable source of scientific data.


5. Long-term Implications and Collaborative Efforts:


The long-term monitoring of marginal conditions in the drilled wells will contribute to the safe operation of the facility. Moreover, the gathered data will be instrumental in amending legislation related to geothermal energy projects. Collaborative efforts among scientific institutions involved in the project ensure that the knowledge gained will benefit not only Litomerice but the entire Czech Republic and potentially other countries with a growing interest in geothermal energy.


6. Challenges and Progress:


The implementation of the geothermal project in Litomerice has faced challenges such as legislative changes, financing options, and evolving societal needs. Delays in finding a suitable drilling contractor posed obstacles, but thanks to the PUSH-IT project, the first stage, including the exploratory wells, is now underway. This financing has not only facilitated the project but also allowed for the incorporation of innovative approaches in drilling and well construction

Litomerice's geothermal energy storage project represents a commendable effort towards sustainable heating and cooling solutions. As drilling commences under the PUSH-IT initiative, the data gathered and lessons learned from this project will undoubtedly contribute to the advancement of geothermal technology not only in Litomerice but on a broader scale, emphasizing the collaborative and innovative spirit of the SYNERGYS project.

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...
