Geothermal Binary Plant

Binary Geothermal Power Plant

Ormat plant configurations are designed to take maximum advantage of the available geothermal energy resources at each site, and provide various binary plants implementations for:
  • Low-temperature geothermal fluid or steam,
  • Separated brine after first or second flash

How it works

  • The fluid is extracted from an underground reservoir and flows from the wellhead through pipelines to heat exchangers in the ORMAT® ENERGY CONVERTER (OEC). 
  • Inside the heat exchangers, the geothermal fluid heats and vaporizes a secondary working fluid, an organic fluid with a low boiling point. 
  • The organic vapors drive the turbine and then are condensed in a condenser, which is cooled by air or water. 
  • The turbine rotates the generator.
  • The condensed fluid is recycled back into the heat exchangers by a pump, completing the cycle within the closed system. 
  • The cooled geothermal fluid is re-injected into the reservoir.
