Just to understand what is meant by Osmotic.

From Google search AI:

Osmotic energy is a renewable power source generated from the salinity difference between fresh and saltwater at the confluence of rivers and the sea. It works by using a semipermeable membrane to allow fresh water to pass into the saltwater, creating pressure that drives a turbine to produce electricity. This form of energy is available 24/7, carbon-free, and has significant global potential, though it is still an emerging technology with ongoing advancements in membrane technology for commercial viability.

How it Works

1. Salinity Gradient:
   The fundamental principle is the difference in salt concentration between fresh river water and saltwater.
   
   
2. • Osmosis:
     This natural phenomenon causes water to move from the area of lower salt concentration (freshwater) to the area of higher salt concentration (saltwater).
     
   • Membrane Separation:
     A semipermeable membrane is used to separate the fresh and saltwater.
     
   • Pressure Generation:
     Freshwater passes through the membrane into the saltwater chamber, increasing the pressure on the saltwater side.
     
   • Electricity Generation:
     This high-pressure water is then used to spin a turbine, which generates electricity.
     

Key Advantages

• • Continuous Power:
    Unlike solar or wind power, osmotic power is a stable, 24/7 energy source, providing consistent electricity day and night.
    
  • Carbon-Free:
    The process is entirely renewable and does not produce carbon dioxide, contributing to a low environmental footprint.
    
  • Abundant Resource:
    The mixing of fresh and saltwater occurs naturally at river mouths worldwide, offering vast global potential for this energy source.
    

Current Status

• • Emerging Technology:
    Osmotic energy is still considered an emerging technology, but recent breakthroughs in nanofluidics and membrane design have made commercialization increasingly viable.
    
  • Pilot Projects:
    Pilot projects are underway globally, such as the OPUS-1 facility in the Rhône estuary (France) and a recently opened plant in Fukuoka, Japan, to advance and scale the technology.

I have no problem with this as long as it doesn't receive any government subsidies.

Japan has launched Asia’s first osmotic power plant, which generates electricity by mixing fresh water with salt water.

The plant will generate about 880,000 kilowatt hours of electricity per year—enough to help run a nearby desalination facility

Something's fishy.
