Vinkovci Uncovers Massive Geothermal Potential: Studies and Documentation Underway By:  Robert Buluma Vinkovci, Croatia – November 3, 2025 Recent research at the Vinkovci GT-1 well has confirmed significant geothermal potential in the area, positioning Vinkovci as the third Croatian city—after Velika Gorica and Osijek—to record reservoir temperatures above 100°C. These findings continue a successful series of exploratory activities led by the  Croatian  Hydrocarbons Agency (Agencija za ugljikovodike) as part of the project “Preparation and Exploration of Geothermal Potential in the Context of Centralized Heating.” Energy of the Future Beneath Vinkovci Mayor Josip Romić expressed his excitement on social media, stating: "Research has confirmed what we believed from the start—Vinkovci and our region hold enormous geothermal potential. Beneath our feet lies the energy of the future, enabling us to reduce dependency on external factors and fluctuating energy prices. This is ...

🌍 From Vision to Reality: Aarhus Powers Its Future with Geothermal Heat By:  Robert Buluma Aarhus, Denmark has officially turned a bold vision into a living reality. The city has become the latest symbol of Europe’s clean energy transition — as geothermal heat now flows directly into Aarhus’ district heating grid for the very first time. This milestone didn’t happen overnight. It’s the result of three years of visionary planning, engineering excellence, and environmental determination by Innargi , in close partnership with Kredsløb and the City of Aarhus. Together, they’ve taken the silent power beneath our feet and transformed it into a renewable energy solution that is set to redefine how cities heat their homes and power their future. 🔬 The Science Behind the Heat At the heart of this transformation lies the Skejby geothermal plant, a marvel of modern engineering. From sandstone reservoirs located 2.5 kilometers beneath the earth’s surface, naturally warm water — reaching temp...

INNARGI  and  H. Anger’s Söhne Seal a Groundbreaking Geothermal Drilling Deal for Denmark and Germany By:  Robert Buluma In a major stride toward Europe’s clean energy ambitions, Innargi A/S, a leading Danish geothermal developer, has entered into a three-year framework agreement with H. Anger’s Söhne Bohr- und Brunnenbaugesellschaft mbH, one of the continent’s most experienced drilling companies. The deal covers the provision of drilling rig services for geothermal projects across Denmark and Germany, marking a significant advancement in the region’s pursuit of sustainable, low-carbon district heating. Under the agreement, approximately 20 deep geothermal wells will be drilled over the next three years, each designed to supply renewable and stable heat to communities. These wells will utilize the City Rig 500, one of Europe’s quietest and most technologically advanced rigs — developed jointly by Anger and Herrenknecht Vertical. The City Rig 500’s design is tailored spec...

🌍 Seismic Surveys Kick Off Geothermal Exploration in Łódź Why Łódź is Going Underground for Clean Heat By:  Robert Buluma In an exciting development for climate-focused energy innovation, the Danish company Innargi has teamed up with Veolia Energia Łódź to explore the geothermal potential beneath the city of Łódź, Poland. A letter of intent signed in late 2024 formalized their long-term partnership to decarbonize the city's district heating system by tapping into renewable geothermal resources. Mapping the Earth: What’s Happening & When Starting around August 11, 2025 , seismic surveys are scheduled to begin across four routes covering approximately 160–186 km throughout the city. Specialized vibro‑trucks will send controlled vibrations—lasting roughly 20 seconds—into the ground. These signals are captured by geophones placed in advance along the planned routes. The data will be used to build a detailed subsurface map in just 4 weeks . Survey operations are prima...
