Salinity gradient energy potential at the hyper saline Urmia Lake - ZarrinehRud River system in Iran

摘要

Salinity gradient has globally high potential for electric energy production, especially where low salinity rivers discharge into hyper-saline lakes. Lake Urmia is world's second hyper-saline lake, with a number of low salinity rivers discharging into the lake, the most significant of which is ZarrinehRud River. Based on thermodynamic calculations and on field data, the theoretical potential of energy production at the above system has been calculated between 400 and 1000 MW, while the technical potential is expected between 40 and 50% of that.
