osmotic power plant

2. Power consumption has been increased enormously across the world so the power generation should be increased. There are many ways of power generation. Some of them leads to environmental pollution. So, non conventional power plants must be encouraged.

5. Sidney Loeb Thor Thorsen Torleif Holt The late US professor Sidney Loeb had the idea to use membranes for desalination in the Early 1970s when he discovered that a similar process could be used to generate power. Back then,power prices were low that no one was interested in investing to develop this technology. Later on, the researchers Dr. Thor Thorsen and Dr. Torleif Holt at SINTEF began to research osmotic power in 1996. Inventor & Researchers Of Osmotic Power Plant

6. Osmosis means passage of water from a region of high water concentration (often freshwater) through a semi permeable membrane to a region of low water concentration (often NaCl). The membrane only lets water molecules pass. Salt molecules, sand, silt and other contaminants are prevented to do so. OSMOSIS:

7. When placing a semi -permeable membrane (i.e. a membrane that retains the salt ions but allows water through) between reservoirs containing fresh water and sea water respectively, a net flow of water towards the salt water side will be observed because of osmosis. If the saltwater compartment has a fixed volume the pressure will increase towards a theoretical maximum of 26 bars. This pressure is equivalent to 270 meters high water column.

8. FIRST OSMOTIC POWER PLANT PROTOTYPE BUILT IN NORWAY This is built by the company Statkraft , opened in November 2009.

9. SEA LEVEL OSMOTIC POWER PLANT SYSTEM ANALYSIS: The flexibility and adaptability of the power plant has been of major interest. There is a variety of different designs of a plant, and a selection of these has been modeled to compare the efficiency and energy production. Below three alternatives are discussed and the results from the simulations are given. SUB SEA PRO PLANT PRO PLANT BELOW THE SEA LEVEL
