Tidal energy how does it work

With limited energy resources, South Korea is looking to transition to tidal power, to provide an alternative to fossil fuels and develop emission-free clean energy.

Tidal energy has the potential to offer all the power we need, eliminating the need for fossil fuels. However, as tidal technology has only been available for a few decades, many challenges remain. Almost 10 years ago, the South West Regional Development Agency installed the Wavehub , the most technologically sophisticated open-access site for testing offshore renewable technologies, 16km off the Cornwall coast.

There are definite opportunities associated with tidal and wave stream technologies, which could offer potential solutions in combatting against the world's climate crisis, whilst achieving the UK's net-zero target in Why not read more about harnessing water to generate energy in our Hydropower blog , or learn about the challenges involved in installing micro-hydropower in water networks in our REDAWN EU project blog.

Predictable energy output — tides are predictable and constant, thanks to gravitational forces. Only needing to assess the low or high tide, makes it easier for engineers to design efficient systems.

As technology advances for tidal, it will get increasingly cheaper and efficient. Protects coastal flooding due to the stability of the rock armour under different design conditions. Though accurate at the time of publication, it is no longer being updated.

And, like the wind, the ocean has energy of motion in the form of waves and currents. The Moon's gravitational pull on the side of Earth nearest the Moon pulls the oceans toward the Moon. The oceans bulge on the other side as well.

Find out why. Another form of energy in the ocean is tidal energy. The part of the ocean facing the Moon bulges out. The part of the ocean on exactly the opposite side of Earth bulges out too. So as Earth turns, the ocean surface seems to rise and fall.

Usually, there are two high tides and two low tides each day. Learn more about tides. With all that water moving up and down, we ought to be able to capture some of that tidal energy.
