Wave Energy

Minesto Ltd. [website] states the oceans represent a major source of renewable energy. Different technologies employ different strategies for harvesting that energy. The main sources of ocean energy are:

Tidal streams

Ocean currents

Tidal range (rise and fall)

Waves

Ocean thermal energy

Salinity gradients

Minesto's Deep Green technology is developed to efficiently harvests the energy in tidal streams and ocean currents.

Tidal streams and ocean currents offer safe, reliable and locally produced renewable energy. They have several significant advantages over other renewable energy sources:

Predictable and reliable. Unlike wind, solar and other ocean energy sources such as wave power, tides and ocean currents are almost 100 percent predictable. The endless flows create reliability of the future energy availability.

Global: Tidal streams and ocean currents are available on all continents.

Energy-rich: Moving water is 832 times denser than moving air, creating conditions for efficient energy conversion.

Minimal use of land and no visual impact: In many regions, land is a scarce resource. Therefore, on-shore solutions such as wind and solar compete with other users. Subsea ocean energy technologies such as Minesto's Deep Green are hidden in the depth of the ocean, out of sight and does not compete for land space.

The large resource of tidal streams and ocean currents can be also exploited with relatively small environmental interaction, thereby offering one of the most lenient methods for large-scale electricity generation.

Tidal streams: closing in on commercialisation

Tides are generated by the gravitational forces between the earth, the moon and the sun. This relative motion creates tidal currents that contain a tremendous amount of energy. Since the positions of the sun and moon can be predicted with complete accuracy, so is the tide's movement and stream speed.

Together with the fact that tides are not affected by weather or climate makes tidal energy a reliable, predictable source of clean energy, with all prerequisites to become a significant part of the future renewable energy mix.
