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...

Harnessing Geothermal Energy Alongside Oil: A Global Case Study   By:  Robert Buluma Geothermal energy, the heat derived from the Earth’s core, has long been recognized as a sustainable and reliable energy source. However, its integration with the oil and gas industry is a relatively new and exciting development. This case study explores how geothermal energy is being harnessed alongside oil globally, highlighting innovative projects, technological breakthroughs, and the synergies between these two industries.   The Synergy Between Geothermal and Oil Industries This Geothermal Decade saw a rise in Oil and Gas companies vouching for Geothermal Energy The oil and gas industry brings decades of expertise in subsurface exploration, drilling, and reservoir management—skills that are directly transferable to geothermal energy development. Both industries rely on similar technologies, such as directional drilling, hydraulic fracturing, and high-temperature equipment, m...
