Blowout at Cape Station: Fervo Energy’s First Major Crisis After Blockbuster IPO

Just weeks after a record-breaking IPO, the flagship project of the "geothermal unicorn" faces its first major operational crisis. By : Robert Buluma   Beaver County, Utah – The morning of May 27, 2026, began like any other at the Cape Station construction site in rural Utah. Workers for Fervo Energy, the newly public darling of the renewable energy world, were engaged in the complex task of drilling deep into the Earth’s crust to unlock what the company promised would be the future of 24/7 clean power. But by the afternoon, the routine had turned into a crisis. The site had experienced a blowout—an uncontrolled release of fluid or pressure from a well. For any energy company, a blowout is a serious matter. For Fervo Energy, which had just raised $1.89 billion in a blockbuster Nasdaq debut two weeks prior, it represents an immediate stress test of its technology, its safety protocols, and its $7.7 billion market valuation. While the well has since been contained and no injur...

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 ...

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...

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...

Steam and Silence: Why Ethiopia's Geothermal Promise Remains Unfulfilled

Steam and Silence: The Uncertain Fate of Ethiopia’s Geothermal Revolution By : Robert Buluma   Despite sitting on a volcanic rift valley with over 10,000 MW of clean energy potential, Ethiopia produces just 7.3 MW of geothermal power—enough to power a small town, but a fraction of what the nation needs. For a country long dependent on hydropower (which fluctuates with drought) and biomass (which degrades forests), geothermal offers the dream of steady, 24/7 baseload energy. However, as investigations into the flagship Aluto Langano and Tulu Moye projects reveal, the road from geological promise to actual megawatts is fraught with technical failure, financial gridlock, and conflicting narratives. The Ghosts of Aluto Langano The story begins and, in some ways, remains stuck at Aluto Langano. Developed by the former EEPCO (now Ethiopian Electric Power/EEP), this site is a textbook case of high potential meeting harsh reality. The resource itself is world-class. Data confirms a high-te...

Ormat’s Ormega100: How the World’s Largest 100 MW Binary Unit Is Industrializing Enhanced Geothermal Systems (EGS)

The Geothermal Tipping Point: Ormat’s 100 MW Bet on an Engineered Earth By: Robert Buluma   An Analysis of the Ormega100 and the Industrialization of Enhanced Geothermal Systems In the quiet corridors of the Calgary TELUS Convention Centre, amid the hum of the World Geothermal Congress 2026, a threshold was crossed. It wasn’t marked by a flashy prototype or a speculative white paper. Instead, it came in the form of a press release from Reno, Nevada-based Ormat Technologies —a company that has spent six decades drilling, building, and operating quietly in the background of the renewable energy boom. The announcement was deceptively simple: Ormat unveiled the Ormega100, a 100 MW binary power generation unit designed specifically for Enhanced Geothermal Systems (EGS). Buried beneath the technical jargon of heat exchangers and working fluids lies a seismic shift in energy economics. For the last twenty years, the renewable energy narrative has been dominated by the intermittency pro...

Data-Driven Site Selection in Nevada Pushes SLB and Ormat's EGS Development Forward

Breaking Ground Below: How Data-Driven Site Selection in Nevada Is Unlocking the Next Generation of Geothermal Energy Published: June 9, 2026 | By Robert Buluma   In the high desert of northern Nevada, where the sagebrush gives way to volcanic rock and the heat beneath the surface has long been a whispered secret, a quiet but profound shift is underway. It is not marked by the dramatic collapse of a coal plant or the sudden rise of a solar farm, but by something far more subtle: the deliberate, data-driven selection of a patch of earth known as Desert Peak. On June 9, 2026, SLB and Ormat Technologies announced that Desert Peak has been selected as the preferred location for a planned enhanced geothermal system (EGS) pilot. This decision, the culmination of a rigorous multi-site evaluation across several of Ormat’s existing geothermal fields, marks a critical inflection point. It is the moment when enhanced geothermal—long a theoretical promise of limitless clean energy—begins it...
