Saltwater Revolution: How Osmotic Power Could Be the Next Big Clean Energy Source
What Is Osmotic Power and How Does It Work? Osmotic power (or salinity gradient energy) is electricity generated from the natural process of osmosis – the movement of water across a membrane from a dilute solution to a salty solution theguardian.com. At river deltas where freshwater meets the ocean, immense chemical energy is continuously released as the two mix. Osmotic power plants capture a portion of this energy by separating fresh and salt water with special membranes in a controlled setting theguardian.com. The concept has been studied since at least the 1970s, but only in recent years have technological advances
