Main forms of ocean energy

Ocean energy is renewable energy generated during the movement of sea water, which mainly includes temperature difference energy, tidal energy, wave energy, energy tidal energy, ocean current energy, salinity difference energy, etc. Among them, tidal energy and tidal current energy come from the gravity of the moon, sun and other planets, and other ocean energies come from solar radiation.

Ocean energy refers to tidal energy, wave energy, current energy generated during the movement of water from sea, as well as the temperature difference, energy and salt content caused by temperature. difference and difference in salinity of sea water. I can't wait.

Ocean dynamics is a subject that studies ocean force fields and the various mechanical movements caused by thisux these. The ocean force field includes the force field of the atmospheric interface layer, the force field of ocean water masses, and the force field of underwater rock formations.

In the atmospheric interface layer, it is mainly caused by ocean meteorology and material migration caused by the interaction of air and sea; The force field of seafloor rock layers is mainly caused by seafloor expansion, volcanic eruptions, collapse or fracture of hulls, etc. Dynamic effects; Various motion processes caused by the force field of ocean water masses constitute the basic content of ocean dynamics.

Characteristics of marine energy

1. Large reserves and renewable. It is estimated that the available power of global seawater temperature difference energy reaches 10 billion kilowatts, and thatRenewable energy such as tidal energy, wave energy, ocean current energy and sea water salinity difference energy are all about 1 billion kilowatts.

2. The energy flow is unevenly distributed and the density is low. The largest temperature difference between the surface layer of the ocean and the depth of 500 to 1,000 meters is only about 20°C, the largest tidal range along the coast is approximately 7 to 10 meters and the maximum speed of offshore tidal currents is only 4 to 7 knots per hour.

3. Energy is changeable and unstable. Among them, sea water temperature difference energy, ocean current energy and salinity difference energy change slowly, tide and tidal current energy changes in a periodic pattern at short term, and wave energy has significant randomness. The developmentIndustrial-scale tidal power began in the 1960s.
