Definition
Salinity gradient power is the power available from the difference in the salt concentration between sea water and river fresh water and it is often called osmotic power or blue energy. This form of power is available when two solutions with different salinity levels are mixed together. Salinity Gradient Power Conversion (SGPC) is a technology that uses the osmotic pressure, i.e., the chemical potential of concentrated and dilute solutions of salt, to drive a turbine to generate electricity.
Salinity Gradient Power Resource
In order to utilize the salinity gradient power, a large amount of both sea water and fresh water are needed. River mouths, where fresh river water discharges to the sea, are naturally potential areas for SGPC development and are widely distributed around the world (Lewis et al. 2011...
