TAQA and SGI Begin Drilling Tenerife’s First Deep Geothermal Exploration Well: A Major Step for Spain’s Clean Energy Future Image: TAQA equipments in the field  Tenerife crossed an important threshold in its energy transition. The island’s first deep geothermal exploration well, TSA-1, officially entered the drilling phase, marking a historic moment not only for the Canary Islands but for Spain’s wider renewable energy ambitions. For a region long seen as a strong candidate for geothermal development, this is the point where possibility turns into action. The campaign is being carried out by  Soluciones Geotérmicas Integradas , better known as SGI, a wholly owned subsidiary of TAQA , after the project received its critical “Ready-to-Spud” notification from Geotermia de Tenerife, the project owner. That signal may sound technical, but its meaning is simple: all planning, engineering, logistics, and permitting steps are complete, and the drill can finally go into the ground. In...

Sanborn Expands Geothermal Surveying to Accelerate Clean Energy Exploration in the United States By: Robert Buluma Introduction: A New Push Toward Subsurface Clarity The global energy transition is increasingly being shaped not just by how we generate electricity, but by how deeply we understand what lies beneath the Earth’s surface. In this context, geothermal energy has emerged as one of the most promising yet underutilized renewable resources. Unlike solar or wind, geothermal power offers constant baseload energy, independent of weather conditions or time of day. However, its development hinges on one critical factor: accurate subsurface data. In early May 2026, a significant development in this space was announced. Sanborn , through its subsidiary EDCON-PRJ, Inc., revealed an expansion of its geothermal surveying operations across the western United States. This move is not just a routine business expansion; it reflects a growing recognition that advanced geophysical mapping is ...

The IADC Geothermal Drilling 2026 Conference & Exhibition is gearing up to be a pivotal event for the geothermal energy sector, scheduled for November 17-18, 2026, in Copenhagen, Denmark.  By: Robert Buluma This marks the second edition of this specialized conference by the International Association of Drilling Contractors (IADC), building on the success of the inaugural event held in Vienna in March 2025, which attracted over 250 attendees. Unlike traditional conferences that rely on abstract submissions, the IADC has innovated with a Call for Challenges approach. This unique format invites the geothermal drilling community—operators, service companies, engineers, and experts—to submit their most pressing, unresolved challenges. These submissions will directly influence the conference agenda, with the Program Committee selecting the toughest issues for expert-led discussions, case studies, and solution-oriented presentations. The goal? To deliver maximum practical value and ...

Revolutionizing Geothermal Drilling: How Advanced Fluids Conquered Croatia's Deep, Hot Wells By: Robert Buluma Welcome back to Alphaxioms Geothermal News, your go-to source for the latest in renewable energy innovations from around the globe. Today, we're diving deep—literally—into a groundbreaking case study from Croatia that's pushing the boundaries of geothermal exploration. In a region where renewable energy is gaining serious momentum, Newpark Drilling Fluids has just wrapped up a project that's not only a technical triumph but also a beacon for sustainable drilling practices. Leveraging their TerraTherm ™ geothermal drilling fluid technology, they enabled safe and efficient drilling in a high-temperature well exceeding 4,000 meters. This isn't just another drill job; it's a story of innovation overcoming extreme challenges in Eastern Europe's budding geothermal sector. Let's break it down step by step, from the hurdles to the heroic solutions and t...

Breakthrough in Polish Geothermal Energy: Hot Waters Over 100°C Discovered in Podhale By:  Robert Buluma Image:  Polish Geothermal Energy: Hot Waters Over 100°C Discovered in Podhale In late December 2025, Poland's Chief National Geologist, Professor Krzysztof Galos, announced a significant discovery in the Podhale region: access to geothermal waters exceeding 100°C. This revelation came from the Bańska PGP-4 borehole in Szaflary, marking a potential turning point for renewable energy in the country. The drilling rig at the Bańska PGP-4 site in Szaflary, Podhale , a symbol of Poland's ambitious push into deeper geothermal resources. The Unique Geology of Podhale The Podhale basin, nestled between the Tatra Mountains and the Pieniny Klippen Belt, has long been recognized as Poland's premier geothermal hotspot. Its geological structure is unparalleled in the country: a reservoir formed by Paleogene sandstone-shale formations up to 3 km thick, overlying Mesozoic carbonate rock...

Zanskar Secures $115 Million to Redefine Geothermal Discovery with AI By: Robert Buluma Image: Zanskar Secures $115 Million to Redefine Geothermal Discovery with AI The geothermal sector just crossed another psychological milestone. Zanskar , a U.S.-based geothermal developer blending hard geoscience with artificial intelligence, has raised $115 million in Series C financing, marking one of the most significant capital injections yet into AI-driven geothermal exploration. The raise propels the company into a new phase,moving decisively from discovery to grid-scale power generation across the Western United States. This latest round pushes Zanskar’s total equity funding to $180 million, a clear signal that investors now see geothermal not as a niche renewable, but as critical baseload infrastructure for the decades ahead. Big Capital Bets on AI-Native Geothermal The funding round was led by Spring Lane Capital , with continued backing from Obvious Ventures, Union Square Ventures , and...

Versailles Embraces Deep Geothermal Energy to Decarbonize Its District Heating Network By Robert Buluma The historic city of Versailles in France's Yvelines department is taking a bold step toward sustainability. On December 18, 2025, Mayor François de Mazières and Franck Lacroix, Deputy Managing Director of Engie , signed a 32-year concession agreement. This partnership entrusts Engie with transforming, modernizing, and greening the city's district heating network, aiming to slash carbon emissions while providing reliable, renewable heat to residents. At the project's core is deep geothermal energy, harnessing the natural heat from underground aquifers. The site targets the Dogger aquifer, a limestone formation from the Middle Jurassic period, located about 1,500 meters below the Paris Basin. Water in this layer reaches temperatures of around 60°C, making it ideal for heating. The plan involves drilling a geothermal doublet two wells: one to extract hot water and another t...

Włocławek Goes Deep: Poland's Latest Leap into Geothermal Energy – A Game-Changer for Clean Heating? By: Robert Buluma Deep beneath the historic streets of Włocławek, a quiet revolution is about to begin. On January 7, 2026, the city signed a landmark contract to drill the exploratory geothermal well Włocławek GT-1, plunging approximately 2700 meters into the earth right next to the local heating company, Miejskie Przedsiębiorstwo Energetyki Cieplnej (MPEC). This isn't just another construction project—it's a bold step toward ditching coal, slashing emissions, and tapping into the Earth's endless heat to warm homes in an eco-friendly way. In the coming days, massive drilling rigs will start humming to life, boring through layers of rock and sediment in search of hot, mineral-rich waters that could completely transform how Włocławek heats its apartments, schools, factories, and public buildings. If the results are positive, this single borehole could open the door to a ...
