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 ...

On July 29, 2024, a significant milestone was reached in China's quest for clean energy. The China National Petroleum Corporation (CNPC) announced the approval of two pilot geothermal heating projects in Xianghe County and Dachang Hui Autonomous County. These projects, part of the largest geothermal heating cluster in the Jing-Jin-Ji (Beijing-Tianjin-Hebei) region, mark a significant step forward in China's clean energy transition.

Geothermal energy, with its abundant reserves, stable output, high utilization efficiency, and economic feasibility, stands out as a key player in China’s renewable energy strategy. Unlike fossil fuels, geothermal energy does not emit greenhouse gases, making it an ideal candidate for the country’s ambitious carbon reduction goals under the "Dual Carbon" strategy. 

Recognizing the potential of geothermal energy, local governments in Xianghe and Dachang have been proactive in accelerating its development. Earlier this year, in January and March, CNPC's Dagang Oilfield inked agreements with these counties to collaborate on geothermal heating projects. The goal is clear: replace traditional coal and gas heating with clean, sustainable geothermal energy.

The scale of these projects is impressive. Together, they will provide heating for a staggering 2.4 million square meters of space. Following the agreement, CNPC swiftly mobilized its resources. Leading the charge was the Dagang Oilfield Exploration and Development Research Institute, which partnered with the Oilfield Production Technology Research Institute and the Oriental Geophysical Company. This powerhouse team delved deep into the geothermal geology of the two counties, tackling complex challenges such as the region's intricate structural features, rapid thermal reservoir changes, and unclear resource scales.

Their efforts have laid a solid foundation for the projects. Through meticulous research and analysis, they have pinpointed favorable geothermal well targets and refined the pilot project plans. This meticulous groundwork will pave the way for the next stages of feasibility studies and construction.

These geothermal projects are not just another step in Dagang Oilfield's geothermal industrialization journey—they are a landmark achievement. As these pilot projects progress, Dagang Oilfield is committed to ensuring they meet high-quality standards, are feasible, and ultimately, profitable. The aim is to create a demonstrative clean heating project that will set a precedent for the entire North China region.

With this development, China is once again proving its commitment to a sustainable future, showcasing the potential of geothermal energy as a cornerstone in the global fight against climate change. The success of these projects could very well serve as a model for other regions, both within China and beyond, looking to harness the power of the Earth for a cleaner tomorrow.

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...
