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 ...

"Rising from the Heat: Europe Embraces the Power of Geothermal Energy"

Forget about relying on finite sources of energy. Europe is turning towards a renewable and unlimited energy source - geothermal. With France, Iceland and Hungary leading the way, several countries are investing billions of euros in this energy source to meet their energy demands.

A Rich European Tradition

Europe has a rich history in geothermal energy, with Iceland, France, and Hungary dominating the sector. However, in recent years, more and more countries have shown an increased interest in exploring the potential of this renewable energy source. Geothermal energy is 100% renewable, unlimited, and reliable - making it a valuable resource in the race towards decarbonization. The ongoing conflict in Ukraine has highlighted the continent's vulnerability in the energy sector and has only reinforced the trend towards investing in geothermal energy.

Decarbonizing 25% of Energy Demand

Geothermal power plants are estimated to provide up to 10% of the electricity demand in Europe. The substitution of fossil fuels with geothermal energy could decarbonize up to 25% of the entire population's energy demand, according to EU data. This means that this renewable energy source is finally getting the attention it deserves and is helping to increase the continent's energy independence and achieve ambitious climate goals.

Driven by GermanyCurrently, Germany is leading the way in the transition to geothermal energy. At the end of 2022, the German government released a plan to increase geothermal production ten-fold, reaching 10 TWh by 2030. Monaco, with its perfect geological location, has planned an investment of one billion euros in geothermal energy by 2035 with the goal of reducing CO2 emissions and gaining energy independence.

France's PlanThe French government has also recently announced a new action plan for the development of geothermal energy. The goal is to produce enough geothermal heat in 15-20 years to save 100 TWh of gas each year and achieve carbon neutrality by 2050. In 2021, geothermal energy represented only 1% of the country's final heat consumption, equivalent to about 6 TWh.

Italy and Other Countries

While Italy is still debating how to support the expansion of geothermal energy, Hungary is already looking to boost production, replacing about 1-1,5 billion cubic meters of natural gas per year. The largest geothermal heating plant in Europe is expected to be completed by 2030 in the city of Aarhus, Denmark. This facility should be able to cover about 30% of the area's energy demand.

Energy transition refers to the shift from traditional, fossil fuel-based energy systems to more sustainable, clean and renewable energy sources. There are several ways to achieve an energy transition, including:

Increased Renewable Energy Generation: One of the most effective ways to achieve energy transition is by increasing the generation of renewable energy sources, such as wind, solar, hydro and geothermal power. This can be done through government policies, subsidies and investment in new technologies.

Energy Efficiency Measures: Improving energy efficiency across all sectors is another key way to achieve energy transition. This can be done through better building insulation, use of efficient appliances, and better urban planning and transportation.

Electrification of Transportation: The transportation sector is a significant contributor to greenhouse gas emissions. The transition to electric vehicles (EVs) and other low-emission modes of transportation, such as public transportation and cycling, can help reduce emissions from the sector.

Decentralized Energy Systems: Decentralized energy systems, such as microgrids, can help communities become more self-sufficient and reduce their reliance on centralized energy systems.

Carbon Capture and Storage (CCS): CCS is a technology that captures carbon dioxide emissions from industrial processes and stores them underground, preventing them from entering the atmosphere. This technology can help mitigate emissions from sectors that are difficult to decarbonize, such as cement and steel production.

Nuclear Energy: While nuclear energy is a controversial energy source, it does have the potential to play a role in achieving energy transition, especially in countries with a large existing nuclear power infrastructure.

It's important to note that an energy transition is a complex and multi-faceted process, and no single solution will work for every country. A successful energy transition will likely require a combination of these strategies, tailored to the specific needs and resources of each country.

Embrace the heat and join Europe's journey towards a sustainable future powered by geothermal energy.

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...
