    Ocean Thermal Energy Conversion Introduction. Ocean thermal energy conversion, or OTEC, uses seawater to turn solar energy into electricity. It relies on the ocean’s thermal gradient - the temperature decline from the sun-warmed waters on the surface to the cold waters found at great depths.

Ocean Thermal Energy Conversion Karen Anne Finney University of Guelph, Guelph, Ontario, N1G 2W1, Canada Ocean Thermal Energy Conversion (OTEC) is a process that employs the natural temperature difference between the surface and the depths of the ocean.

First introduced inOTEC has been described as an effective and renewable energy Size: KB. Ocean Thermal Energy Conversion is a process using the heat energy that is stored in the ocean. The oceans collect a huge amount of the world’s heat energy.

OTEC uses the heat differences between deep and shallow ocean waters to evaporate a fluid to run a steam turbine and generate. Ocean Thermal Energy Conversion Companies Ocean Thermal Energy Corporation (OTEC) Ocean Thermal Energy Corporation (OTE) traces its roots to when our predecessor company began researching and developing the technologies known as Ocean Thermal Energy Conversion (OTEC)and Seawater Air Conditioning (SWAC).

Ocean thermal energy conversion or simply OTEC is the process of using the ocean itself as a solar technology is still highly theoretical, and utilizes the slight temperature gradient between the warm surface of the ocean and the cooler water deeper down.

This technology operates in a similar way that solar ponds do but on a much larger scale. View Ocean Thermal Energy Conversion Research Papers on for free.

While environmental impacts studies of OTEC concluded the benefits of the technology outweighed its impacts, further research is needed in the following areas (“NOAA”): Withdrawal and Discharge Water: Given a MW facility, billion gallons of warm surface water and cold water from depths around meters would be used each impacts of large water volume discharge need.

Vishwakarma Institute of Technology, Pune, B Tech Mechanical Engineering 14 CONCLUSION Ocean thermal energy conversion is a potential source of renewable energy that creates no emissions i.e.

it is fuel free. It has a low environmental impact, can supply pure water for both drinking and agriculture purposes. Can supply refrigeration and cooling.

OTEC is not like wind power or solar power (which are intermittent), because the technology can operate on a basis. Oceans act as incredibly large solar energy collectors, absorbing about 80% of the sun’s energy.

This means that every day, the oceans on our planet absorb solar energy equivalent to billion barrels of oil, and if we could convert % of this energy into electricity. Closed Cycle: Closed cycle Ocean Thermal Energy Conversion systems use a working fluid with a low boiling point, Ammonia for example, and use it to power a turbine to generate seawater is taken in from the surface of the oceans and cold water from the deep at 5 warm seawater vaporizes the fluid in the heat exchanger which then turns the turbines of the generator.

OTEC, ocean thermal energy conversion is an energy technology that converts solar radiation to electric power.

Ocean thermal energy conversion (OTEC), form of energy conversion that makes use of the temperature differential between the warm surface waters of the oceans, heated by solar radiation, and the deeper cold waters to generate power in a conventional heat engine.

The difference in temperature between the surface and the lower water layer can be as large as 50 °C (90 °F) over vertical. OCEAN THERMAL ENERGY CONVERSION • Ocean Thermal Energy Conversion (OTEC) is an electricity generation system. • In equatorial areas the temperature between the warm surface water and the deep cold ocean water differs by about 20°C.

• Bigger the temperature difference, the higher will be the efficiency. change have become major issues. The growth of environmental awareness and the rising demand for energy has urged researchers to identify other sources of renewable energy.

The heat stored in the ocean can be converted into electricity by means of a process called Ocean Thermal Energy Conversion (OTEC), which uses the ocean’s natural temperatureFile Size: KB.

Ocean thermal energy conversion For many years, scientists have been aware of one enormous reservoir of energy on the earth's surface: the oceans. As sunlight falls on the oceans, its energy is absorbed by seawater. The oceans are in one sense, therefore, a huge "storage tank" for solar energy.

The practical problem is finding a way to extract that energy and make it available for human use. Ocean thermal energy conversion (OTEC) makes use of the temperature differences between the deep cold and relatively warmer surface waters of the ocean to generate a constant, clean source of electricity.

This constancy differs from the output of renewable resources such as wind and wave energy that sometimes produce intermittent electricity. Ocean thermal energy conversion (OTEC) is a way of getting useful energy from the world's sun shines on the oceans of the world and in the hot parts near]] the water at the sea's surface can be quite warm, sometimes as high as 30°C.

Many oceans are very deep and the water at depths of 1, meters can be around 5 °C. If a pipe is put down into the ocean we can bring the cold. Most of our energy waste in North America results from Answer A.
