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.

Ormat's REG system captures waste heat to heat the Organic working fluid (directly, or through intermediate heat media). The heated working fluid vaporizes and expands in a turbine, which is connected to a generator that produces electricity.

... Toluene is identified as the organic fluid with the maximum thermal efficiency compared to R123 and R245fa [23]. Benzene and Methanol exhibit higher efficiency and lower fluid flow demand than other fluids [24] .

The organic Rankine cycle is is similar to the Rankine steam cycle, but uses an organic fluid such as refrigerants and hydrocarbons instead of water as the working fluid. The ordinary Rankine cycle uses thermal power to convert water to steam, which expands through a turbine in order to generate electricity.
