Introduction
⚫Theocean cover 75% of theworld surface.
⚫It is the largest renewable energy source of
earth thatcan reduce greenhouseemissions.
⚫ Theocean havepower in different form i.e.
-waveenergy
-tidal energy
-ocean temp. differenceenergy

OBJECTIVE
To reduce the useof fossil fuel.
Obtain theeconomical load scheduling.
Foreconomical production costchooseas the base
load plant with diesel orgas powerplant.
Reducing otherauxiliary equipment i.e.-cooling
towerash handling coal handling oil etc.
Avoid from variousenvironmental issue i.e.
-greenhouseeffect
-solid wastes
-acid rain etc

Broadly form of ocean energy
Waveenergy
Tidalenergy
[Ocean energydue to] temp. difference
of oceanwater.
Note- we focused onlyabove twotopic

Wave energy

Tidal energy
Tidal energy is the potential difference
b/w tidal cycle head and tail. which is
carried by the action of sun and the
moonof theoceanwater

Different techniques to make
useable of ocean energy
TIDAL BARRAGE

Utilization of wave energy
*It consist a

Wave capture device

How much energy and what types?
-250 Billion barrelsof oil worth of energy coming into
ocean everyday
-80 million barrels of oil perday produced
Theoretical global resourceof ocean energy:
8,000-80,000 TWh/yr for wave energy 800 TWh/yr for
tidal current energy 2,000 TWh/yr for salinity gradient
energy 10,000 TWh/yr forocean thermal energy
World’selectricityconsumption 17,000 TWh/yr

Application
Powersupplied light towerthose navigatesship.
Powersupplied cities those localized at shoreof ocean.
Used forelectrification of ship (f loaterpower) .
Powersupplied togrid.
Individual powersupplied for locally industriesat the
shoreof ocean (Tidal energy used)
Powersupplied tocommunication towerthat is used
forreceiver, transmitterorrepeater.

Advantages
Onceyou’ve built it then ocean power is free .
Nogreenhouseeffectcreated.
No fuel requirement.
Noany solid waste managementproblem.
Reduces auxiliary equipment i.e. cooling tower
pre heater boileretc.
Economical production cost.
Useas base powerplant.

Disadvantage
Effect on marine ecosystem- as clean as
wave energy is it still creates hazards for
someof theanimal near it.
Suitable to certain locations-the biggest
disadvantage togetting yourenergy from
thewave location. only powerplants and
towns near the ocean will benifit directly
from it.

Conclusion
Ocean resources are immenseyetdiffuse
and expensive toexploit.
Itsan energy that have big potential to be
moredeveloped
In future this could represent another
solution in renewable source of energy so
that the management in this areacould be a
more sustainable business.
