Efficient large-scale power generation from geothermal and other low-grade heat sources may now be viable, thanks to a revolutionary new technology. A team led by Behdad Moghtaderi, professor at the University of Newcastle Centre for Energy, worked with Granite Power Ltd (GPL) to develop the technology platform called Granex. It delivers higher efficiencies than conventional power plants and increases the quantum of power that can be generated from low-grade natural heat and industrial waste sources. A 100-kilowatt pilot plant set up at the varsity will enable a comprehensive power generation programme over a wide range of operating conditions.
