Saltwater Revolution: How Osmotic Power Could Be the Next Big Clean Energy Source
The world’s first commercial osmotic power plants opened in Denmark (2023) and Japan (2025), using salt and fresh water to generate electricity around the clock. Advances in nanomaterial membranes have boosted output to 20–25 W/m² and cut costs sharply. Osmotic power now supplies steady, zero-emission energy for industrial sites and homes. Studies suggest global potential could reach 10–20% of electricity demand.
