Germany’s Urban Geothermal Gamble: Inside the Massive 3D Seismic Campaign Beneath Erfurt’s Streets by Geofizyka Torun By : Robert Buluma In the heart of Germany, something extraordinary is happening beneath the sidewalks, apartment blocks, cafés, and busy streets of Erfurt. While most residents move through their daily routines unaware, fleets of heavy vibrotrucks and thousands of seismic receivers have been quietly scanning the Earth below the city in one of Europe’s most ambitious urban geothermal exploration campaigns. The recent completion of a demanding 3D seismic survey campaign by Geofizyka Torun S.A. marks far more than a technical milestone. It represents a glimpse into the future of European energy — a future where cities no longer rely heavily on imported fossil fuels, but instead tap into the immense heat hidden beneath their own foundations. Germany’s geothermal race is accelerating, and Erfurt has suddenly become one of the most fascinating battlegrounds in Europe’...
PGEO's Geothermal Ambition Ignites: Lumut Balai Unit 2 Nears Full Power by June 2025 By Alphaxioms | June 18, 2025 In the heart of Sumatra’s steamy rainforest, a silent revolution is unfolding one that doesn't spew smoke or roar with turbines, but hums with the promise of a greener tomorrow. PT Pertamina Geothermal Energy Tbk (PGEO) is racing against time to power up its PLTP Lumut Balai Unit 2 , and with the first successful synchronization to PLN’s grid, the countdown to full commercial operation by June 2025 has officially begun. ⚡ The Beginning of a Brighter, Cleaner Era On June 16, 2025, PGEO achieved a crucial milestone: initial synchronization of Lumut Balai Unit 2 at 10% capacity (around 5.5 MW) of its total 55 MW output. What may sound like a small step was, in fact, the spark igniting a larger geothermal ambition. This step not only marks the start of transmitting electricity into the national grid, but it is also a powerful symbol of Indonesia’s forward march t...
