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’...
In a landmark move for clean energy in the Azores, Exergy ORC has secured a contract to revamp the Ribeira Grande geothermal power plant on São Miguel Island. By : Robert Buluma This pivotal project is being undertaken in collaboration with EDA Renováveis, and it marks Exergy's second geothermal venture in the region—reinforcing its commitment to advancing the energy transition during what is now widely regarded as the "Geothermal Decade." A Tailor-Made Solution for a Sustainable Future As part of the modernization, two outdated geothermal units will be replaced with a state-of-the-art, 5 MW Organic Rankine Cycle (ORC) system. This advanced solution has been specifically designed to enhance the performance and efficiency of the Ribeira Grande plant, utilizing geothermal resources more effectively and sustainably. The goal is not just to boost energy output, but to support São Miguel’s broader ambition: to run entirely on renewable energy. With the integration of Exergy...
