The system developed by Enertime is set to help generate up to 5,000 megawatts per year from the waste heat of a foundry in western France.
"The factory will use the electricity produced by the machine," David said.
"That will replace electricity bought on the grid, and this electricity will be cheaper than the grid, so there will be a major saving for the industry," he added.
Enertime's technology can also be used in biomass plants, diesel power plants, in marine vessels and the geothermal energy sector.
A key advantage of the system is that it is essentially self-sufficient and can be left to its own devices.
"It is completely… (automatic), and remote controlled from our offices here, while the factory is around 200km away," David said.
"In some operations organic rankine cycles have been running for months without anybody checking," he added.
