Eavor Geretsried Geothermal Breakthrough: Inside the Closed-Loop Energy Revolution, Drilling Challenges, and Path to Scalable Clean Power

The Geothermal “Holy Grail” Just Got a Reality Check: Inside Eavor’s Geretsried Breakthrough By: Robert Buluma   May 22, 2026 It’s not every day a deep-tech energy company publishes a detailed technical report that openly documents what went wrong on its flagship project—and still comes out looking stronger. That’s exactly what Eavor Technologies did with its Geretsried geothermal project in Bavaria, Germany. The result is unusually transparent: part technical post-mortem, part validation of a technology many have doubted for years. And the core message is simple. They built it. It works. But it wasn’t smooth. The short version Eavor is trying to solve one of geothermal energy’s hardest problems: how to produce reliable heat and power anywhere, not just in rare volcanic hotspots. Their claim has always been bold: a closed-loop geothermal system that is scalable, dispatchable, low-carbon, and independent of natural reservoirs. Critics have long argued it wouldn’t survive...

Ecopetrol Explores Geothermal Energy in Caldas, Colombia

Exploring the Potential of Geothermal Energy in Caldas, Colombia



In recent years, the world has been witnessing a shift towards renewable energy sources, and Colombia is no exception. With its rich natural resources and commitment to sustainable development, the country is embarking on an exciting journey to harness geothermal energy, particularly in the region of Caldas.


Geothermal energy, derived from the Earth's internal heat, has long been recognized as a clean and reliable source of power. Unlike fossil fuels, geothermal energy produces minimal greenhouse gas emissions and offers a consistent power supply, making it an attractive option for sustainable energy generation.


Caldas, situated in the heart of Colombia's coffee region, is poised to become a hub for geothermal energy exploration. Recent advancements in technology and partnerships between government agencies and private companies have paved the way for significant investments in geothermal projects in the region.


One such project gaining momentum is led by the Colombian state-owned company Ecopetrol, in collaboration with multinational corporations like Baker Hughes Company and local utility Chec. Together, they are spearheading efforts to explore and develop geothermal resources in Caldas.


The initiative received a significant boost with the recent announcement of plans to invest in drilling activities and advance the development of geothermal energy generation. With an investment of approximately $25 million, Ecopetrol, Baker Hughes, and Chec are gearing up to construct two exploratory wells to assess the potential of geothermal reservoirs in the region.


According to Santiago Villegas Yepes, manager of Chec, these initial explorations will provide crucial insights into the quantity and quality of geothermal resources available in Caldas. The ultimate goal is to establish a geothermal power plant capable of generating around 30 megawatts of electricity, enough to power approximately 200,000 households in the region.


This ambitious endeavor marks a significant milestone in Colombia's renewable energy journey and underscores the country's commitment to reducing its carbon footprint. By tapping into its geothermal potential, Caldas has the opportunity to not only diversify its energy mix but also create new economic opportunities and promote sustainable development.


Moreover, the project holds promise for addressing energy poverty and promoting social equity in the region. With access to clean and affordable 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 ...

GEN Electric Grid Impact Study RFP in Framingham Massachusetts Advances Utility Geothermal Networks

GEN Electric Grid Impact Study RFP Signals a Defining Moment for Geothermal Energy Networks in the United States By: Robert Buluma The United States geothermal sector is entering a new phase, one where geothermal systems are no longer being viewed only as sources of heating and cooling, but increasingly as strategic infrastructure capable of strengthening the electric grid itself. In one of the most important emerging developments in utility-scale thermal network deployment, the Home Energy Efficiency Team (HEET), in partnership with Eversource Gas, has officially launched a Request for Proposals (RFP) for a groundbreaking Electric Grid Impact Study focused on Geothermal Energy Networks (GENs), also referred to as Thermal Energy Networks (TENs). Backed by funding from the U.S. Department of Energy under grant “DE-EE0010662.0002 Home Energy Efficiency Team Utility-Managed Geothermal Pilot in Framingham, Massachusetts,” the initiative represents far more than a local energy pilot. It is...

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...

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...
