Antigua and Barbuda Invests in Nevis Geothermal Energy Project

Caribbean Geothermal Awakening: Why Antigua & Barbuda’s Interest in Nevis Could Redefine Energy in the Eastern Caribbean By Robert Buluma | Alphaxioms Geothermal Insights | May 2026 For decades, the Caribbean has lived under the shadow of imported fossil fuels. Island nations blessed with sunshine, volcanic systems, ocean resources, and powerful geothermal reservoirs have nevertheless remained trapped in one of the world’s most expensive electricity markets. Imported diesel and heavy fuel oil have dictated national budgets, strained public finances, inflated electricity bills, and exposed small island economies to global geopolitical shocks far beyond their control. Now, however, something transformative is beginning to emerge beneath the volcanic islands of the Eastern Caribbean. Antigua and Barbuda’s recent declaration that it is willing to acquire an equity stake in the geothermal project under development in Nevis may appear, at first glance, like a routine regional investmen...

XGS Energy Thermal Reach Energy Geothermal Revolution

Revolutionizing Geothermal Energy: XGS Energy's TRE Technology



Geothermal energy, often overshadowed by its more prominent counterparts like solar and wind power, is poised to undergo a significant transformation thanks to groundbreaking technology developed by XGS Energy. In a recent announcement, XGS unveiled its innovative Thermal Reach Enhancement (TRE) concept, signaling a new era for the geothermal sector.

Traditionally, geothermal power generation involves tapping into natural heat reservoirs beneath the Earth's surface by drilling wells and extracting hot water or steam to drive turbines. However, XGS's approach introduces a novel twist by integrating oil and gas techniques with cutting-edge material science.


At the heart of XGS's TRE technology lies a proprietary material that boasts an impressive thermal conductivity, surpassing that of conventional rock by a staggering 50 times. This material acts as a conduit, facilitating the rapid and efficient transfer of heat from the surrounding rocks to the working fluid circulating within the wellbore.


The key to XGS's innovation lies in its closed-loop process, which eliminates the need for large-scale hydraulic fracturing and mitigates concerns over induced seismicity. Unlike enhanced geothermal systems (EGS) that rely on extensive fracturing to connect injector and producer wells, XGS's approach offers greater geographic applicability and a lower carbon footprint.


Moreover, XGS's technology promises to revolutionize the economics of geothermal power generation. By maximizing heat absorption and minimizing drilling complexities, XGS aims to deliver cost-competitive electricity with levelized costs projected to be as low as $35/MWh.


The journey towards commercialization is well underway, with XGS securing substantial investments and gearing up for field tests. The company's ambitious timeline targets the drilling of commercial geothermal wells producing up to 10 megawatts thermal by 2026, paving the way for widespread adoption and integration into the energy grid.


In summary, XGS Energy's TRE technology represents a game-changer for the geothermal industry, offering a scalable, sustainable, and economically viable solution to meet the world's growing energy demands. As the transition towards cleaner energy sources accelerates, XGS's innovation holds the promise of unlocking the vast potential of geothermal power and reshaping the global energy landscape for generations to come.

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 ...

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...

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...

LCOE Benchmarking: Eavor Technologies vs. Fervo Energy

LCOE Compared: Eavor Technologies vs.  Fervo Energy   Two Bets on Next-Generation Geothermal An Alphaxioms Geothermal Insights Analysis | May 2026 Image:  Eavor and Fervo Drilling Rigs well poised in their respective well pads , drill baby , baby what a time to be a live Introduction: Why the Cost Question Matters Now The global geothermal sector is in the middle of a pivotal moment. After decades of stagnation largely confined to volcanic hotspots, two fundamentally different technological approaches are racing to prove that geothermal energy can be deployed broadly, cheaply, and at scale. Eavor Technologies , the Calgary-based advanced geothermal systems (AGS) company, and Fervo Energy , the Houston-based enhanced geothermal systems (EGS) pioneer, represent the sharpest divergence in next-generation geothermal strategy today. Each company is backed by hundreds of millions of dollars in private capital, each has reached key commercial milestones, and each is advancing ...

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...
