3. Blue Energy
Energy available from the difference in
the salt concentration between sea
water and river water.
It is also known as “Reverse Electro-
Dialysis” (RED).
12. Parameters
Energy Produced = 250kW
(It can go up to 4.5 GW)
Size Of The Plant = 90 meter square
Working Pressure = 11 – 15 bar
Water quantity required per second on average = 3300
cubic meter
THE DATA IS DERIVED FROM THE RUNNING PLANT IN THE NETHERLANDS
13. River Delta
The River Delta is a place where a river and an
ocean or a sea meets.
Example of such ‘River Deltas’ are
(i) Rhine River Delta in the Netherlands
(ii) Sundarban in India
16. Comparison With
Other Renewable Sources
Parameters Solar Energy Wind Energy Blue Energy
Continuity of

Discontinuous Discontinuous Continuous
Cost High High Low
Energy Generation Low Low High
17. Advantages
Renewable source of energy
Efficiency found to be 85 to 90%
Energy can be got 24 hours continuously
Almost Pollution free technique
Large availability of ‘river-deltas’ in the world
19. Future Prospects
The project is under research and efforts are
being put to reduce the cost of the
membrane.
Researchers have estimated that it can render
to 40% of the world wide demand.

Editor's Notes
From thermodynamic calculations, it can be derived that each mtr cube of river water can yield 1.4 MJ when mixed with the same amount of sea water.
80 lacs approx. for full capacity(4.5 GW) . 20 pounds per mt sq. membrane.
For 66 MW, 4.5 rs per Kwh. 0.4 KV to 170KV.
