Principle of Osmotic Power

SaltPower is based on the technology of Pressure Retarded Osmosis (PRO). Two water sources with different salinity are mixed via a membrane to produce electricity. Water flows across the membrane and builds up pressure, and by passing the pressurized water through a turbine electricity is generated.

The power of osmosis explained from hydropower

How tall should a hydropower dam be before it will produce the same power as an osmotic power plant operating on water with high concentration of salt? Several thousand meters.
