Transcript of History of Wave Energy


1799: First patent of a device designed to use ocean waves to generate power

1910: First oscillating water column was built by Bochaux-Praceique to power his house

1940s: Yoshio Masuda experimented with many concepts of wave power

2004: Wave power was delivered to an electrical grid for the first time

How are Waves Caused?
Waves contain a massive amount of energy
Wave power devices extract energy directly from the surface motion of ocean waves or from pressure fluctuations below the surface.

Wave Power Areas
The western coasts of
Scotland
Northern Canada
Southern Africa
Australia
and the northwestern coasts of the United States.

Wave Energy Technologies
Area to be installed
Nearshore
Offshore (40 m)
Far offshore

Installation
All wave energy technologies are intended to be installed at or near the water's surface

They convert the energy of the waves into other energy forms, usually electricity
Devices
Terminator devices
Limited by Betz effect
59.3% kinetic energy conversion limit
Tidal Stream Generators
Captures or reflects the power of the wave to spin a turbine
Typically onshore or nearshore
Offshore turbine



How it works
1)
Waves arrive at power station
2)
Waves cause water to rise and fall in chamber
3)
Air is forced in and out of the hole at the top of the chamber
4)
Air turns turbine, which powers generator
Con:
Possibly very noisy without a silencer
Noise of device usually drowned out by waves

Wave Energy
History of Wave Energy
In Logistics View
Maritime logistics helps the transportation of awkward vehicles used for wave energy
Pros
The energy is free
no fuel is needed and no
waste is produced
Inexpensive to operate and maintain
Can produce a significant amount of energy.
Green

Cons
Depends on the waves – variable energy supply
•  Some designs generate noise
•  Must be able to withstand very rough weather
•  Costly to develop
•  Threat to navigation
•  May obstruct mooring and fishing
•  May degrade scenic ocean front views
Can disturb or disrupt marine life (toxic spills)

For instance, there is tidal
turbine handler for loading,
unloading and maintenance.
Conclusion
Good idea, but not yet developed enough
Will be a major player in the natural energy supply in the future
At the moment, too many cons
