A. Solar energy
B. Thermal energy
C. >D .Wind energy
The source of energy for ocean temperature difference is solar energy. Among all types of ocean energy, ocean temperature difference energy belongs to ocean thermal energy, and its main energy source is solar axial radiation energy contained in the ocean.
Expand knowledge:
The ocean is illuminated by the sun and converts energy from solar radiation into ocean thermal energy. In tropical and subtropical areas, surface sea water is maintained between 25 and 28 degrees Celsius and the temperature of deep sea water a few hundred meters away is stabilized between 4 and 7 degrees Celsius through the conversion of the thermal energy of the oceans. and the lower layers ofsea water with different temperatures as sources of heat and cold, they can use their temperature differences to produce electricity.
With the exception of a small part of the solar energy received by the ocean which is directly reflected into the air, most of it will be absorbed by seawater. Water As the sea absorbs solar energy, water molecules move faster and the water temperature increases.
In this way, the radiant energy of sunlight is converted into the kinetic energy of the thermal movement of seawater molecules and stored. Solar energy stored in seawater is what is often called ocean thermal energy.
When it comes to ocean depth, although it is “measurable” in terms of data, the mysteries contained in seawater thousands of meters or even tens of thousands of meters deep, can still be described coeven “not measurable” describe.
Sunlight can only shine on the surface of seawater. As the depth of seawater increases, the amount of sunlight passing through it decreases. The deep sea area where sunlight cannot reach is a dark ocean world. This creates a large difference between the surface seawater temperature and the deep seawater temperature.
For example, the surface water temperature of the Persian Gulf and the Red Sea can reach 35°C, but at a depth of 500 to 1,000 meters underwater, the temperature of sea water is only 3 to 6°C. This vertical temperature difference causes the "uneven hot and cold" of sea water. It is this temperature difference that contains huge energy, which is the energy of the ocean temperature difference.
Develop knowledge - Solar energy:
Solar energy is ae source of renewable energy. It refers to the energy of thermal radiation from the sun and its main manifestation is often called solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters.
Since the birth of life on earth, it has mainly relied on the energy of thermal radiation provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method. to prepare food, such as making salt and drying salted fish.
As fossil fuels decline, solar energy has become a significant part of human energy consumption and continues to grow. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy sourceyou. Solar energy in a broad sense also includes wind energy, chemical energy, hydropower, etc. on earth.
The source of energy for ocean temperature difference is solar energy. ocean temperature difference energyIt belongs to ocean thermal energy, and its main energy source is solar radiation energy contained in the ocean. The ocean temperature difference energy has the characteristics of huge reserves and relatively stable changes over time. Using ocean temperature difference energy to generate electricity is expected to provide stable, large-scale energy in some regions.
What is the source of ocean temperature difference energy?
Seawater temperature difference power generation technology uses ocean water surface sea (25℃ - 28℃) heated by solar energy cosame source of energy at high temperature. A heat source, with sea water 500 to 1,000 meters deep (4℃ to 7℃), is used as a low temperature heat source, and a thermodynamic cycle system composed of a heat engine is used to produce electricity.
The main use of ocean temperature difference energy is temperature difference energy production. From high temperature heat source to low temperature heat source, efficient energy can be obtained with a total temperature difference of about 15℃. -20℃.
