Ocean thermal power generation
Ocean thermal energy conversion The biggest advantage of the device is that it can work continuously without being affected by tide changes and ocean waves. In addition, it does not produce air pollutants or radioactive waste, and its by-product is high-quality desalinated seawater. The water temperature of tropical sea surface is usually about 27 ℃, and the water temperature of deep sea is kept several degrees above freezing point. Such temperature gradient makes the energy conversion of ocean thermal energy conversion device only reach 3%~4%.
Therefore, the ocean heat energy conversion device must use a lot of water to make up for its low efficiency. In fact, 20%~40% of the electricity is used to pump water into the device and around the heat energy conversion device through the water inlet pipe. Although OTEC device still has many problems in engineering technology and cost, it has great potential after all. Futurists believe that it is an important part of the world's transition from oil to future pollution-free hydrogen fuel. Some scientists even believe that OTEC is harmless to the environment and may provide all the energy needed by human beings.
