Prenzlau’s Geothermal Breakthrough: A Decisive Step Toward a Fully Renewable Heat Future By: Robert Buluma The city of Prenzlau, located in northeastern Germany, has reached a major milestone in its transition toward sustainable energy. In December 2025, Stadtwerke Prenzlau announced a decisive breakthrough in its geothermal project after successfully encountering geothermal water at a depth of 983 meters. This discovery represents a critical step forward for the city’s ambition to fully decarbonize its heat supply and positions Prenzlau as a leading example of how medium-sized towns can harness geothermal energy for district heating. The geothermal water discovered during drilling operations is estimated to be around 200 million years old and is contained within a saline sandstone formation deep underground. With a temperature of approximately 44°C and a planned production rate of 130 cubic meters per hour, the resource offers a reliable and continuous source of renewable heat. A test...

Strataphy and Baker Hughes Forge Strategic Alliance to Accelerate Geothermal Cooling and Saudi Arabia’s Energy Transition By: Robert Buluma Saudi Arabia’s journey toward a low-carbon, diversified energy future has taken a decisive step forward with the signing of a strategic Memorandum of Understanding (MoU) between Strataphy and global energy technology leader Baker Hughes. Announced in Khobar in December 2025, the partnership signals a powerful convergence of deep-tech innovation and industrial-scale execution,aimed squarely at accelerating geothermal cooling and advancing the Kingdom’s broader energy transition agenda. At a time when cooling demand is surging across the Middle East,driven by rapid urbanization, giga-projects, data centers, and industrial expansion,this collaboration positions geothermal energy not merely as an alternative, but as a cornerstone technology for sustainable infrastructure in Saudi Arabia. A Landmark Agreement with Strategic Implications Under the MoU,...

An Eight-Billion-Forint Geothermal Bet: Drilling the Future Beneath Kiskunhalas By Robert Buluma | Alphaxioms Insights |  Beneath the vast plains of Hungary’s Great Alföld, immense heat has been quietly stored for millions of years. Now, that hidden energy is poised to reshape the country’s energy future. The region around Kiskunhalas is set to become a focal point of Hungary’s geothermal ambitions, following the signing of a HUF 7.86 billion (approximately EUR 20 million) contract for geothermal drilling and well-testing works. The agreement was signed by a subsidiary of MVM Group , Hungary’s state-owned energy company, and covers geothermal exploration activities to be carried out over the next three years across several areas of the Great Plain. This marks one of the most significant state-backed geothermal initiatives in Hungary in recent years. Unlocking Earth’s Heat to Cut Energy Dependence The project’s strategic objective is clear: to pave the way for geothermal power pla...

Constellation–Calpine Merger: Why Geothermal and Firm Clean Power Now Matter More Than Ever By: Robert Buluma The U.S. electricity sector is entering a defining moment, one where scale, regulatory scrutiny, and the search for firm clean power, are converging. The approval of Constellation’s $26.6 billion acquisition of Calpine is not just a headline-grabbing merger; it is a powerful signal about the future structure of power markets and the growing strategic value of geothermal energy and other always-on renewables. As federal regulators force divestments, allow unprecedented scale, and reassert antitrust authority, one question becomes unavoidable: **where does geothermal fit in a power system increasingly dominated by mega-utilities? The Deal,and Why It Matters for Clean Baseload To close the acquisition, Constellation agreed to divest six power plants and a minority stake in a seventh across Texas, Pennsylvania, and Delaware. These concessions were demanded by federal regulators c...

PGEO’s Big Leap: Powering Indonesia’s Green Data Centers with Geothermal Energy By: Robert Buluma Indonesia’s digital economy is expanding at breakneck speed. With more than 212 million internet users, rapid cloud adoption, AI deployment, fintech growth, and government-led digitalization, the country is witnessing an unprecedented surge in demand for data centers. But behind the glowing screens and humming servers lies a critical question: how will Indonesia power this digital future sustainably? PT Pertamina Geothermal Energy Tbk (PGEO ) believes it has the answer,green data centers powered by geothermal energy. In a landmark move that could redefine the intersection between energy and digital infrastructure in Southeast Asia, PGEO has unveiled plans to expand its business into geothermal-powered green data centers, a first-of-its-kind initiative in Indonesia. This strategy places geothermal energy not just as a baseload power source, but as a cornerstone of the country’s low-carbon d...

Connecticut’s Groundbreaking Geothermal Network: Heating the Future in New Haven By Robert Buluma   In the heart of New Haven, Connecticut, a quiet but revolutionary clean-energy transformation is unfolding beneath city streets. What lies underground could redefine how American cities heat and cool their buildings. New Haven has officially begun construction of Connecticut’s first networked geothermal energy system, a project designed to provide ultra-efficient, low-emission heating and cooling to the city’s historic Union Station and a major new public housing development nearby. More than a local infrastructure upgrade, this initiative marks a decisive step toward New Haven’s ambitious climate goal: fully decarbonizing municipal buildings and transportation by 2030. Even more significantly, it positions the city as a blueprint for how thermal energy networks could be scaled across Connecticut and eventually, the United States. Union Station: A Historic Landmark Meets Clean Energy...

El Salvador's Volcanic Awakening: How the Berlin 2 Plant is Powering a Nation's Bold Leap into the Future By: Robert Buluma Imagine a land where ancient volcanoes rumble beneath the surface, not as harbingers of destruction, but as silent guardians of boundless energy. In El Salvador, the smallest nation in Central America, this isn't just poetic fancy,it's reality. On December 13, 2025, amid the lush hills of Usulután, the inauguration of the Berlin 2 Binary Cycle Plant marked a seismic shift in the country's energy landscape. With a thunderous applause from engineers, officials, and locals alike, President Nayib Bukele's vision for a modern, self-sufficient El Salvador ignited into life. This isn't just another power plant; it's a beacon of innovation, harnessing the Earth's fiery core to light up millions of homes. Buckle up as we dive into this captivating story of renewal, resilience, and raw power. El Salvador has long been a geothermal powerho...
