Exergy’s  Gemini Turbine: Redefining the Future of Large-Scale Geothermal Power By:  Robert Buluma In a bold leap forward for geothermal innovation, Exergy International has once again raised the bar with the unveiling of its groundbreaking Gemini Turbine — a next-generation powerhouse that delivers up to 60 MWe on a single shaft . Announced in Olgiate Olona, Italy , the Gemini marks a monumental evolution in Exergy’s proprietary Radial Outflow Turbine (ROT) technology, setting a new benchmark for efficiency, scalability, and cost-effectiveness in large-scale geothermal power generation . The Dual-Engine Revolution At the core of Gemini’s innovation is a reimagined turbine architecture that merges two turbines into one high-capacity unit . Its dual-inlet design allows working fluid to enter symmetrically from both sides, expanding radially outward through a central rotor disk equipped with mirrored rotor stages. This unique configuration achieves unmatched mechanical b...

🌍 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...
