Dynelectro, Syntholene, and the Geothermal SOEC Breakthrough in Iceland Dynelectro’s role in the Syntholene Iceland project highlights a major shift in how the market should think about SOEC technology. For years, solid oxide electrolysis cells have been seen as highly efficient but too difficult to commercialize because of stack degradation, short operating life, and the complexity of integrating them into real industrial systems. This project helps challenge that view by showing how geothermal integration, advanced power electronics, and system-level design can make SOEC a credible industrial solution.   The most important takeaway is simple: the market has often misunderstood SOEC as a technology limited by chemistry alone, when in fact a large part of the challenge is operational. Dynelectro’s approach shows that if the stack is controlled properly and supported by the right electrical architecture, SOEC can move much closer to commercial viability. The Syntholene Iceland ...

Exclusive interview with Exergy : discover the new Gemini dual-flow radial outflow turbine, the first single-unit ORC solution for 30–60 MW geothermal projects, offering up to 30 % lower costs and 99 % availability. By:  Robert Buluma .   An interview with  Luca Pozzoni -  Deputy CEO | Group CFO - Exergy International and the Exergy Team 1. Can you walk us through the key design innovations in your new Gemini turbine and how it differs from previous models? The major innovation of the Gemini turbine lies in the dual-flow configuration: unlike conventional radial outflow turbines which are equipped with a single bladed overhung rotor disk, the Gemini features a double-side bladed rotor disk mounted in a between-bearing configuration. This enables the efficient processing of significantly larger volumes of fluid, leading to higher power output having basically two radial outflow turbines in a single machine with enhanced operational stability and simplified mainte...

“Inside the Next Wave of Geothermal Innovation: Opportunities, Risks, and Global Impact” By:  Robert Buluma An indepth interview with Cary Lindsey, PhD Research Scientist Great Basin Center for Geothermal Energy, Nevada Bureau of Mines and Geology, University of Nevada Reno  1. Enhanced Geothermal Systems (EGS) are often described as geothermal's "breakout technology." From a geological standpoint, what are the biggest unresolved uncertainties preventing large-scale commercial deployment ? The progress we've seen in EGS over the last few years has been incredible. For a long time, geothermal was largely limited to places where nature had already done the hard work for us by creating hot, permeable reservoirs. EGS opens the door to developing geothermal resources in places that were previously off the table. That said, there are still some big questions we need to answer. Can we maintain those engineered reservoirs for decades? How much liquid (water or brine) will the...

Krafla Magma Testbed (KMT) : Humanity’s Bold Leap Into the Heart of the Earth Interview  from Bjorn Gudmundsson the C.E.O-Krafla Magma Testbed and Team By:  Robert Buluma In 2009, deep beneath Iceland’s iconic Krafla volcano, a drilling team made history. During the IDDP-1 project, their drill bit pierced into magma molten rock at just two kilometers below the surface. What began as an accident became a scientific revelation. For the first time, humans had safely accessed magma. This “Eureka” moment gave birth to an idea so daring it almost sounds like science fiction: the creation of a permanent observatory where magma could be directly studied. That idea became the  Krafla Magma Testbed (KMT) a visionary international project that promises to rewrite the future of geothermal science, volcanic monitoring, and sustainable energy. Why Krafla? The Perfect Laboratory Beneath Our Feet Krafla’s  geology is unique. It offers a known shallow magma body, decades of research...

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...

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...
