As the name suggests, ocean thermal energy takes advantage of the fact that temperatures of each layer within a large water body differ. The by-products of this comprehensive process is desalinated freshwater which improves the scope of fish farming in several regions. The ultraviolet radiation from sunlight excites the water molecules at the surface of the ocean, causing a rise in temperature. Thomas, G.P.. "Ocean Thermal Energy: An Untapped Resource". There are several great advantages to ocean thermal energy. Moreover, OTEC includes a few Disadvantages as well which are as follows –. For example, the construction of a large (3-megawatt) OTEC plant was planned off the coast of the Ivory Coast but was abandoned due to the lack of sufficient funds in the 1950s. The larger the difference, the higher is the effectiveness of this method of producing renewable energy. AZoCleantech. The turbine, therefore, generates electricity when it is attached to a generator. Neither text, nor links to other websites, is reviewed or endorsed by The Ohio State University. Therefore, scientists use liquids, such as ammonia, which have a low boiling point to produce thermal energy from the temperature difference. This can lead to a thriving ecosystem around the conversion plant, and farmable fish can also be introduced into areas that they would not have previously survived in. This could decrease carbon emissions by half a million tons.

OTEC is a sustainable source of energy that relies on thermal and solar power. Ans. As the name suggests this combines elements of both systems. Only a small variation in output takes place from season to season. The by-products of this process are also beneficial for fish farming purposes. Though there has been relatively little investment and research into ocean thermal energy compared to other renewable energies, the idea of harnessing this energy source is not a new one. This stands out over many other types of sustainable energy such as solar energy which can only be collected while the sun is out or wind energy that can only be collected on a windy day, Another Synergetic product that is created during ocean thermal energy conversion is cold water. Finally, OTEC used as a closed cycle is very low risk. Geoff Pocock, Managing Director and Founder of the Hazer Group talks to AZoCleantech about how the Hazer Process is producing clean hydrogen with Near-Zero Carbon Emissions. By using all synergetic products to their potential and with the energy produced by OTEC then the energy saving potential can be up to 90%, OTEC is a very immense resource with the availability of this resource being able to produce 4x the world’s electrical needs.

This stands out over many other types of sustainable energy such as solar energy which can only be collected while the sun is out or wind energy that can only be collected on a windy day 1. The sunlight that hits the ocean is stored as though the ocean was a giant solar panel. Generally, the optimum situation for the conversion of ocean thermal energy to electrical power is when the temperature difference between surface and deep water is around 36oF (20oC). C, which is sufficient for ammonia to boil.

The main distinctions between the machines are briefly outlined below. There are several different types of Ocean Thermal Energy Conversion (OTEC) systems that have been implemented at various times. OTEC becomes a part of a continuous process of sustainable energy generation which significantly reduces the impact of global warming. Do you have a review, update or anything you would like to add to this article? Thomas, G.P.. "Ocean Thermal Energy: An Untapped Resource". The process of Ocean Thermal Energy Conversion mainly leverages the gap in the temperature gradient present at several layers of seawater. There are several more advantages to OTEC that make it a very promising source of renewable energy for the near future. Pro, Vedantu This idea is not new but actually dates back to 1881, when a French engineer by the name of Jacques D’Arsonval first thought of OTEC. In 1881, French physicist Jacques-Arsene d’Arsonval proposed this alternative form of energy creation to battle the slow depletion of non-renewable sources of energy.
