Organic Rankine Cycle in Geothermal energy power plant Air-cooled condenser technology enables us to re-inject almost 100% of all extracted geothermal fluids, thereby avoiding the use of geothermal steam condensate or external water resources for cooling and preventing the need for chemical additives.

Inside the heat exchangers, the geothermal fluid heats and vaporizes a secondary working fluid which is organic, with a low boiling point. The organic vapors drive the turbine and then are condensed in a condenser, which is cooled by either air or water.

Ormat offers unique renewable power solutions based on the ORMAT^® Energy Converter (OEC), a power generation unit which converts low, medium and high temperature heat into electrical energy.

Organic Rankine Cycle is a technology that convert low-temperature heat sources into a mechanical energy, and it can be used to produce electrical energy in a closed system. The heat sources can be received from renewable energy such as geothermal, solar, and biomass.
