Alphaxioms Geothermal News and Related Research Globally

Alphaxioms, we talked to Chris Sladen about his involvement in geothermal both in the UK, and globally By:  Robert Buluma Chris, please begin by explaining a little about yourself, and why you have a passion for geothermal? I have spent over 45 years involved in energy. Following undergraduate studies in geology at Southampton University, and a PhD in sedimentology at Reading University, I joined the energy sector in Aberdeen in 1980. It was a fascinating era when it seemed like at least one giant oil & gas field was discovered offshore every month; the wealth creation for the UK was gigantic. I got to see so much geology and rocks - my true passion. I moved to China in late 1983; not today’s China, this was over 40 years ago, a country closed for decades and embarking on an open-door policy, in part to bring both investment and technology. I became very interested in energy trends, energy politics, and new geography created by changing politics leading to opportunities for ene...

XGS Energy  Achieves 3,000-Hour Milestone for Water-Independent Geothermal System By : Robert Buluma HOUSTON, Sept 30, 2025 – In a groundbreaking achievement for the geothermal sector, XGS Energy has announced the successful 3,000-hour operation of its water-independent geothermal system at commercial scale. This milestone not only validates the system’s commercial economics but also positions XGS as the first company to demonstrate such technology under real-world, commercial conditions. A New Era in Geothermal Innovation The operations took place at the Coso Geothermal Field in California’s Western Mojave Desert, a site owned by Atlantica Sustainable Infrastructure and operated by Coso Operating Company. XGS Energy  revitalized a well that had been idle for over two decades, installing its proprietary closed-loop geothermal system enhanced by Thermal Reach Enhancement (TRE) technology. Flow testing delivered a record performance, maintaining a sustained temperature differenc...

Medco Power  Kicks Off Geothermal Drilling in Bonjol, Targeting 60 MW Clean Energy By:  Robert Buluma Pasaman, West Sumatra – Indonesia’s transition to clean energy has reached another milestone as PT Medco Power Indonesia , through its subsidiary PT Medco Geothermal Sumatra,  officially began drilling its first geothermal exploration well in Bonjol, Pasaman Regency. The inaugural well, BNJ-1 , was spudded on 11 September 2025 in a ceremony attended by the Governor of West Sumatra, Mahyeldi Ansharullah ,  Medco Power President Director Eka Satria , local government leaders, traditional community representatives, and local stakeholders. A Step Toward 60 MW of Renewable Power This drilling marks the first of two planned wells, with a total estimated potential of 60 MW of clean electricity. The project, categorized as part of Indonesia’s National Strategic Projects under the Electricity Supply Business Plan (RUPTL 2025–2034), is expected to be completed by the ...

Zanskar  Strikes Geothermal Steam Again: A New Era in Clean Energy By:  Robert  Zanskar's Geothermal and Minerals , a trailblazer in AI-native geothermal exploration, has achieved another significant milestone by uncovering a substantial geothermal reservoir in northern Nevada. This discovery marks a pivotal moment in the company's mission to revolutionize the geothermal energy sector. Innovative Approach to Geothermal Exploration Founded in 2019, Zanskar has been at the forefront of integrating artificial intelligence with geothermal exploration. By leveraging advanced machine learning algorithms and subsurface data, the company has been able to identify geothermal resources that were previously overlooked or deemed too risky. This approach has not only accelerated the discovery process but also significantly reduced the costs associated with geothermal development. The Northern Nevada Discovery The recent discovery in northern Nevada is particularly noteworthy. Utilizin...

Robert Buluma :  Alphaxioms Responses were provided by Jeanine Vany, Executive Vice-President of Corporate Affairs, Eavor . Can you explain the key technological advancements in the latest iteration of the Eavor-Loop™ system? We have made a number of technological advancements at our project in Geretsried Germany . This includes innovation and learning resulting in dramatic improvements in our drilling performance and we’re proud to talk about our technology. For example, Eavor recently announced successful implementation of our in-house AMR (active magnetic ranging) tool which makes drilling more accurate and efficient. Eavor-Link™ AMR uses magnetic ranging while drilling to maintain constant alignment as it drills two wells at approximately 100 metres apart before they are intersected to create a continuous geothermal loop, which is then sealed with Eavor’s proprietary Rock-Pipe™ formula. With real-time data transmission between downhole sensors, the technology ensures tighter bo...
