What Exergy does
Exergy International Srl is an Italian private limited company founded in 2000 and headquartered in the Milan area, operating as a specialist designer and manufacturer of Organic Rankine Cycle (ORC) power systems and Industrial Heat Pumps. The company's core technology centers on its proprietary Radial Outflow Turbine (ROT) architecture — most recently embodied in the Gemini Turbine with up to 60 MWe per shaft and over 90% efficiency — which converts low-to-medium temperature heat into clean electricity. Exergy's portfolio spans tailor-made large-scale ORC systems plus modular products (ORC-lite, PureCycle, Gas Expander, Industrial Heat Pumps) addressing geothermal, industrial heat recovery, biomass, concentrated solar power, and cold energy recovery applications.
The company generates revenue primarily through one-time sales of custom-engineered ORC plants to enterprise customers (geothermal utilities, cement, steel, glass, LNG, and biomass operators), supplemented by recurring after-sales service and maintenance contracts across its installed base of 581 MW across 63 plants worldwide. Sales are conducted via direct enterprise field sales with regional managers and global trade-show presence at Cemtech Europe, GRC, World Geothermal Congress, and European Geothermal Summit, among others. The company is owned and coordinated by tica-exergy srl and has a stated headcount of 101–250 employees. Recent strategic activity includes the Gemini Turbine launch (Oct 2025), contract wins in Turkey (46 MWe) and the Azores (5 MW revamp), and an R&D partnership with TU/e on AI-enhanced plastic recycling (Jan 2026).

Three partnerships are on record, tiered core.
- TU/e (Eindhoven University of Technology) - Polymer Performance Materials groupcoreExergy partnered with TU/e's Polymer Performance Materials group on the RVO-funded AI-STRAP project to develop an AI-enhanced solvent-based recycling process for complex plastic waste streams such as multilayer packaging and e-waste. The collaboration combines polymer science with machine learning to create an adaptive recycling system that dynamically optimizes solvent selection and process parameters based on variable feedstock compositions. Funded through the EKOO Circular Plastics 2025 program.
- EDA RenováveiscoreExergy was awarded a contract by EDA Renováveis for the revamping of the Ribeira Grande geothermal power plant on São Miguel Island, Azores. The project includes the replacement of two existing units with a new 5 MW tailor-made ORC system, representing a significant revamping and upgrade engagement with the Azores utility.
- Maren Maraş Elektrik Üretim A.Ş.coreExergy signed a deal with Maren Maraş Elektrik Üretim A.Ş. for the supply of two geothermal power plants in Turkey (Emir and Nezihe Beren 2 projects). The projects will add 46 MWe of clean power capacity to Turkey's geothermal market, raising Exergy's geothermal portfolio to approximately 540 MWe.
