“IHI has developed a micro-binary power cycle of 20kW output to generate power with water heated at 70 to 90℃ and is preparing to sell it from 2013.

Binary power generation is a method to generate electricity by repetition of vaporization and liquefying cycle so called “Organic Rankine Cycle” in use of a heat medium having a low boiling point. It is now drawing attention as a method to generate electricity with a low-temperature heat like warm water which has so far been thought to be difficult for use.

This power generation method is also closely related to the industrial gas technology because it uses a gas having a lower boiling point like fluorocarbon for heating medium, instead of water.

Developing a small type of generator for an output of 20kW class, IHI successfully made the binary power generation implemented by any plant where there is just a little warm water available. Although the heat medium has not been disclosed in detail as yet, they say they will use a fluorocarbon heating medium of which ozone depletion potential is zero with less global warming potential.”
