Japan's first osmotic power plant started operations in early August in a southwestern prefecture.
The plant uses the difference in salt concentration between seawater and fresh water to generate electricity.
The technology is described as a next-generation renewable energy source unaffected by weather or time, emitting no CO2.
Electricity is produced via osmotic process using a permeable membrane separating concentrated seawater and treated water.
A turbine is rotated by water movement from fresh to saltwater, generating electricity.
The plant in Fukuoka is expected to produce 880,000 kWh annually, powering a desalination facility.
The project is praised as a significant step for renewable energy, with hopes for global adoption.
