Ocean Thermal Energy Conversion
The more we use renewable energy, the more we benefit the environment, strengthen our energy security, create jobs locally, and help improve our economy
Types of energy resources
• Non-renewabe
– Cannot be replenished or renewable
• Fossil fuels
• Nuclear energy
• Renewable
– Can be replenished or renewed
• Geothermal
• Hydropower
• Ocean energy
• Solar energy
• Wind energy
• Biomass energy
Renewable: ocean energy
• Still in experimental stage, not common
• Three types:
– Waves energy
– Tidal energy
– Ocean thermal energy
Ocean energy: waves
When the air flows, turbine is turned and it would drive the generator.
Electricity is produced.
Ocean energy: tidal and thermal
• Tidal energy
– similar to hydropower plant
• dam traps the sea water when high tide
• when tide drops, water flow turns the turbine and drives the production of electricity of generator
• Ocean thermal energy
– application of the temperature difference of sea water
OTEC Description
• Oceanic Thermal Energy Conversion
• OTEC utilizes the ocean’s 20ºC natural thermal gradient between the warm surface water and the cold deep sea water to drive a Rankine Cycle
• OTEC utilizes the world’s largest solar radiation collector - the ocean. The ocean contains enough energy power all of the world’s electrical needs.
