Innargi Geothermal, Decarbonising Europe's Heat, One City at a Time In an era defined by the urgent need to decarbonise Europe’s energy systems, one critical sector often remains overlooked, heating. Accounting for a substantial portion of the continent’s energy consumption, the heating sector has long been dominated by fossil fuels and biomass. Enter Innargi Geothermal, a Danish company on a mission to change that, one community at a time. Founded in 2017 by A.P. Møller Holding, Innargi has rapidly evolved from a single-project venture in Aarhus into an international geothermal energy company with a growing portfolio across Northern and Eastern Europe. By applying decades of subsurface expertise from the oil and gas industry to the untapped potential of geothermal energy, Innargi is industrialising geothermal district heating at a scale never before seen in the European Union. This article takes a deep dive into Innargi’s operations, exploring its revolutionary business model and ...
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...
