Tidal Power
The tide is created by gravitational tugs from the moon and the
sun. They are a powerful force along the shore.
Tidal power is a form of hydropower that converts the energy
of tides into electricity. This is one of the technology used as a
natural energy resources like solar and wind power.
<Tidal power plant has been made in many countries.>
Korea
France
Generation of tidal energy
Tidal power uses difference of tidal range.
Occur that tidal range changes
Open a dam and water flow
Turbine rotates
Get electricity
Characteristic
Advantage
Disadvantage
Fuel is not required,
Project the output exactly.
Cost performance is bad.
Difficult to establish.
In Japan, there is a large tidal range as the Tsugaru,Kanmon
and Naruto Strait. But there is no better place to establish a
large scale tidal power plant.
Tidal power is not expanded in Japan yet.
NOVA ENERGY Co.LtD.
It is a venture company established in MAY 2007 and located
in Hyogo. This company has been conducting research and
development of new energy.

NOVA ENERGY Co.LtD.
Experiment
Research in Kanmon Strait
Kitakyusyu started to develop tidal power plant with a
company or university in this year.
The speed of the tide is fast : Max 4.8m/s
This research has not commercialized yet. And it is
difficult to use widely in Japan.
If tidal power is available widely in Japan. We can
reduce the emission of CO2.
