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...

Košice Turns Up the Heat: Geothermal Energy to Warm the City After 30 Years in Waiting By: Robert Buluma After three decades of anticipation, the city of Košice, Slovakia, is finally set to tap into one of the Earth’s cleanest and most sustainable energy sources geothermal heat. On Wednesday, drilling begins on the long-awaited project “Utilization of Geothermal Energy in the Košice Basin”, marking a major leap toward energy independence and carbon neutrality for Slovakia’s eastern metropolis. From the site of Svinica–Ďurkov, a new deep geothermal well will be drilled, expected to reach a temperature of 135°C and a flow rate of 55 liters per second. Two reinjection wells each plunging roughly 3,700 meters deep  will accompany the main production well, ensuring a closed-loop system that reuses and reheats the geothermal water beneath the Earth’s surface. The third and final well is expected to be completed by mid-2026. Turning Vision into Reality The geothermal heating project is be...

🌍 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...
