Košice Ignites Its Geothermal Future: A 30-Year Dream Becomes Reality”

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...

Driving the UK Toward Net Zero: Chris Sladen on Geothermal’s Untapped Potential

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...
