Exergy Launches Gemini Turbine for Enhanced Large-Scale Geothermal Power Generation
Exergy International has launched the Gemini Turbine, a new Radial Outflow Turbine (ROT) capable of generating up to 60 MWe from a single shaft, designed to enhance efficiency in large-scale geothermal power generation. With a dual-inlet design and isentropic efficiency exceeding 90%, the turbine offers a compact alternative to multi-turbine setups, promising a 30% reduction in power plant costs. As investments in advanced geothermal technologies approach US$2 billion in 2024, global geothermal capacity is expected to surpass 800 GW by 2050, contributing approximately 8% of the world's electricity.

Exergy International has introduced the Gemini Turbine, a significant advancement in its Radial Outflow Turbine (ROT) technology, capable of delivering up to 60 MWe from a single shaft. Developed entirely in Italy, the Gemini Turbine features a dual-inlet design, improving efficiency and scalability for next-generation Enhanced and Advanced Geothermal Systems (EGS and AGS).
The turbine can handle volumetric flows exceeding 50 m³/s with isentropic efficiency above 90%, offering a compact alternative to multi-turbine setups. It promises a 30% reduction in power plant costs and improved project economics. As investment in next-generation geothermal technologies has surged to nearly US$2 billion in 2024, global geothermal capacity is projected to exceed 800 GW by 2050, accounting for around 8% of the world's electricity.
