1. Osmotic Power Plant
(still in Research and Development
stages)

2. Osmotic Power plant how
it work.
• * Osmotic is what we call when we
transport water through a
semipermeable membrane.
• How it works. We start with
transporting seawater and
freshwater in two different
containers with a semipermeable
membrane between them.
• Then the seawater molecule gets
pulled to the freshwater and when
that happens the pressure in the
freshwater tank gets higher and
will lead the water in the second
pipe to a turbine.
• That will produce power.

3. PROS
OSMOTIC IS A RENEWABLE SOURCE OF ENERGY.
AND IT’S ENVIRONMENTALLY FRIENDLY.
IN THEORY IT CAN BE BUILT EVERYWHERE
FRESHWATER IS FLOWING OUT TO THE SEA.
AND YOU CAN PRODUCE POWER WHENEVER
REGARDLESS OF WEATHER.
Pros with Osmotic
Power Plants

4. BUT OF COURSE THERE ARE SOME CONS IN THIS. LIKE I HAVE
TOLD YOU, THIS IS NOT SOMETHING WE ARE USING IN
NORWAY RIGHT NOW.
WE ARE ONLY RESEARCHING IT. BECAUSE WITH TODAY’S
TECHNOLOGY, WE WILL ONLY GAIN ENOUGH POWER FROM
THIS METHOD BY BUILDING CONTAINERS AS BIG AS A
FOOTBALL STADIUM.

5. An Example of what we can do with an
Osmotic Power Plant
• If we have an Osmotic Power Plant with a
semipermeable membrane of 5 million square
meters, and that will produce 25 MW that
again will produce 166 GWh power in the
year. That’s enough for 30000 EU houses.
