Ormat's binary cycle technology

Ormat's binary cycle technology captures geothermal heat by circulating it through a heat exchanger to transfer thermal energy to a secondary fluid with a low boiling point. This secondary fluid vaporizes and drives a turbine connected to a generator, producing electricity. The primary geothermal fluid remains underground, allowing continuous use without depletion. This method enables the efficient harnessing of moderate-temperature geothermal resources, making it a reliable and environmentally friendly way to generate electricity from geothermal heat sources that are not hot enough for traditional steam turbines.
