Japan has built Asia’s first large-scale osmotic power facility, a breakthrough energy plant that generates electricity simply by mixing freshwater and saltwater. By harnessing natural differences in salinity, this innovative technology opens the door to a new, continuous, and renewable energy source available along coastlines and river mouths. It’s a major step forward in Japan’s push for clean, low-impact power generation. • Osmotic power works by placing freshwater and seawater on opposite si
