What Is Ocean Thermal Energy Conversion?

Ocean thermal energy conversion is a method that uses the ocean temperature difference, that is, the temperature difference between the surface of the ocean heated by the sun and the colder and deeper waters. As heat flows from one layer to the other, the heat engines in both layers take some heat and convert it into usable energy. ^[1]

Difficulties in Ocean Thermal Energy Conversion

Ocean temperature difference power generation is still a high-tech project, which involves many problems with pressure resistance, heat insulation, anticorrosive materials, and the use of thermal energy. The investment is huge, and the country cannot support it. Due to the late start of research and development of renewable energy technology, its economic benefits are still currently lower than non-renewable energy sources such as coal and petroleum. When a large water pipe is placed at a depth of 500 meters, the operation is very difficult due to the influence of the ocean current, and shellfish and algae are also attached to it, which reduces the efficiency.

Impact of Ocean Thermal Energy Conversion

When generating electricity, it will cause changes in the temperature of the surrounding seawater and affect marine ecology.

Because the power plant was built in the sea, it caused some pollution to the seawater during construction.

The huge volume of temperature difference power plants will have certain impacts on the surrounding marine life.
