The organic Rankine cycle (ORC) has been widely used to convert low-grade (300°C) thermal energy to electricity. Use of zeotropic mixtures as the working fluids improves the thermodynamic performance of ORC systems due to better matches of the temperature profiles of the working fluid and the...

Electric energy security is essential, yet the high cost and limited sources of fossil fuels, in addition to the need to reduce greenhouse gasses emission, have made renewable resources attractive in world energy-based economies. The potential for renewable energy resources is enormous because...

In order to overcome the electricity demand in the country and in its effort to reduce the greenhouse gas emission and climate change, South African (SA) government is encouraging research in the field of renewable energy (RE). Higher educational institutions in each province are involve in...
