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

By Robert Buluma Alphaxioms
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...

Best Geothermal Drilling Companies in the World: Top Global Leaders, Deepest Wells, Major Projects, and Future Market Outlook

By Robert Buluma Alphaxioms
Best Geothermal Drilling Companies in the World Image: a drilling rig and a geothermal manifestation  Geothermal drilling sits at the center of one of the most important but least understood parts of the clean energy transition. While solar and wind often dominate public discussion, geothermal energy offers something that many power systems still struggle to achieve: firm, dispatchable, low-carbon energy that can run around the clock. The challenge is that geothermal resources are hidden below the surface, which means the industry depends on highly specialized drilling companies capable of working in extreme heat, fractured rock, remote terrain, and high-pressure environments. The best geothermal drilling companies in the world are not all pure geothermal contractors. Some are large oilfield service companies that have adapted their drilling technology to geothermal applications. Others are specialist geothermal drillers with decades of hard-rock and high-temperature experience. A ...

Idle GDC Drilling Machines Put Sh15bn Investment Into Question

By Robert Buluma Alphaxioms
Idle GDC drilling machines put Sh15bn investment into question Image: A GDC Owned Geothermal Rig Kenya’s geothermal ambitions have long been presented as one of the country’s strongest energy success stories. Yet a fresh audit report has exposed a costly weakness inside the Geothermal Development Company , where drilling rigs worth Sh15.93 billion have raised hard questions about value for money, asset management, and the future pace of geothermal expansion. The issue is not simply that machines are sitting idle. It is that these machines were bought for a strategic purpose: to drill wells, unlock steam, and help Kenya expand one of its cleanest and most reliable sources of power. When such expensive equipment remains unused for years, the problem goes far beyond maintenance. It points to a breakdown in planning, operations, oversight, and financial discipline. For a country that relies heavily on geothermal energy to stabilise electricity supply, the implications are serious. Every id...

Geothermal Funding Rounds in June–July 2026: Quaise, Endurance, Hephae, Alberta & the Rise of Next-Gen Energy Investment

By Robert Buluma Alphaxioms
June and July 2026 marked a clear acceleration in geothermal and next-generation energy investing. Capital flowed into companies building the tools, systems, and project models needed to unlock deeper heat, faster deployment, and more reliable clean power.  Image : a thematic view of a geothermal equipment  The strongest signal from these months is that geothermal is no longer being viewed only as a climate technology. It is increasingly being treated as a power infrastructure category with relevance to data centers, heavy industry, utilities, and long-duration energy security. This shift matters because geothermal has always had strong fundamentals, but it has often struggled to attract the scale of capital needed to move from technical promise to commercial deployment. What changed in 2026 is the combination of improved drilling capabilities , stronger investor familiarity with enhanced geothermal systems , and rising demand for firm clean electricity. That mix has made the ...

Reliability-First Geothermal Plant Design: How PGE’s Lumut Balai Unit 3 Turns Fleet Data into High-Availability Baseload Power

By Robert Buluma Alphaxioms
Designing a baseload geothermal plant is not about hitting a single commercial operation date; it is about building a machine that can run hard, almost all the time, for decades.  Pertamina Geothermal Energy’s (PGE) Lumut Balai Unit 3 project shows what it looks like when an operator bakes reliability, data, and predictive maintenance into the plant from day one instead of trying to bolt them on later. Building Reliability In From Day One: Inside PGE’s Lumut Balai Unit 3 Pertamina Geothermal Energy is developing a 55 MW geothermal plant at Lumut Balai in Indonesia that is scheduled to start operations in 2030, but the critical work is happening now, long before first steam. Rather than treating Unit 3 as a standalone asset, PGE is designing it as part of a living fleet,using detailed data from existing units to guide every major decision. Operations director Andi Joko Nugroho captures the mindset in a single line: “A baseload geothermal plant cannot be designed only to achieve comm...

Colorado Geothermal RFP: 6,597 Acres Open for Clean Energy Development

By Robert Buluma Alphaxioms
Colorado Opens 6,597 Acres for Geothermal Development: Why the State’s New RFP Could Reshape America’s Clean Energy Map Image: A map which depicts the land area Colorado has taken a notable step toward becoming a serious geothermal market. In July 2026, the Colorado State Board of Land Commissioners issued a Request for Proposals inviting qualified developers to explore, finance, permit, construct, and operate geothermal energy projects on state trust land across five counties. This is more than a routine land notice. By asking for complete development teams rather than simple speculative leaseholders, Colorado is signaling that it wants real projects, real timelines, and real electricity generation from its geothermal acreage. A different kind of geothermal RFP Most land offerings in the energy sector focus on access rights first and development later. Colorado’s geothermal RFP is broader, requiring bidders to show they can move a project from resource exploration through financing, ...

Eavor steps back from operator role in the Geretsried geothermal project

By Robert Buluma Alphaxioms
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 ...
