The WINDHUNTER SYSTEM concept
is an offshore, floating system that uses several wind turbines for
power output to produce hydrogen by electrolyzing water. This
continuously manned, safe and stable system will be easily maintained
on-board while relocating to the best wind conditions for the wind
turbines. The produced hydrogen gas may be compressed and stored as gas
or liquefied and placed in insulated tanks. The compressed gas or tanks
of liquefied gas may be transferred by helicopter or surface ships with
insulated containers. |
ADVANTAGES OF THIS SYSTEM
1. This is a simple, manned, movable system. No under-water piping or
wiring is used to connect to the sea surface, sea bottom or shore.
2. A multiple of wind turbines can be mounted high above the water's
surface on a vessel to generate electricity that will be used to
electrolyze water and produce hydrogen.
3. Because this system can be relocated easily for better wind energy,
the production rate should be much greater than the usual 30% from a
wind turbine whose location is fixed.
4. This vessel can be anchored or free floating.
5. If the wind speed is too high, the downwind drift speed can be
increased to reduce the wind speed over the rotors so that hydrogen
production can continue.
6. These tall systems can be out of sight from the shore.
7. The ship will be positioned to face the wind and incoming waves by
the action of stern and bow thrusters and or the main propulsion
propellers and rudders.
8. No yaw motion is required for each individual wind turbine because
the ship is always facing the wind and therefore the wind turbine
nacelles will be simpler and lighter.
9. Several wind turbines are rigidly and perpendicularly connected to
the surface of a large framework by the back end of the nacelle and
angle braces.
10. When the framework is in the horizontal position, the vessel is more stable.
11. When the tall framework with the attached turbines is vertical, their height produces the largest power output possible.
12. Each turbine can be inspected and receive minor internal
maintenance during operation while the frame is vertical with access
through the rear of the nacelle from the hollow frame member that may
contain a ladder or an elevator.
13. While at sea, any repair could be completed when the frame is lying
on the deck. That includes removing the blades and nacelle and
installing new parts.
14. This system is the fastest method to generate large quantities of hydrogen with the least public opposition.
15. The hulls can be reworked, old, single-wall oil tankers. Thousands
are available, since they are now illegal to be used for oil transport.
Decommissioned military ships could be retrofitted for the multiple or
single hull arrangements.
16. This system can be used anywhere in the world and can bring hydrogen power to energy poor areas.
17. In the future, clean burning hydrogen can replace the nuclear, oil,
coal and natural gas for electrical power generation. It can also
replace the gasoline and diesel now used for transportation.
18. The wind energy will be available forever and will always be available for harvesting.
19. The US Department of Energy report Feb. 2004 said that wind
turbines and electrolyzing of water is the best way to produce hydrogen.
20. Each turbine will be able to change its rotor speed and blade pitch to deliver maximum power to its own electrolyzer.
21. Each turbine would power one electrolyzer and its hydrogen output
would blend with others before going into the common liquefier or
compressor for tank storage.
22. Damage to birds and bats would be negligible compared to those
caused by land-based turbines. It can be moved away from bird flyways
depending upon the season of the year.
23. Except for the initial construction material and startup fossil
fuel on board, this system is pollution free and would do no
environmental damage to the sea surface or bottom.
24. An environmental impact study may not be necessary.
25. A malfunctioning turbine could be shut down while the others continue to operate.
26. Liquid cooling of the equipment in the nacelles is possible because
the nacelles are rigidly mounted to the hollow vertical columns that
would contain the plumbing lines.
27. The hollow columns will contain the electrical output cables and control wiring.
28. The generated power can be 45 Megawatts or greater for a large
system with nine of the worlds largest turbines and two of the largest
oil tanker hulls.
29. When the framework is horizontal, a shore crane can quickly replace
all the wind turbines resulting in a fast turnaround on shore.
30. The turbine rotors can turn faster than land based units because
there would be no noise or vibration restrictions that are disagreeable
to persons living nearby.
31. While at sea, the hydrogen would be transferred to the shore by helicopters or surface ships.
32. This concept can be applied to all sizes of vessels.
33. The potential for storm damage will be less than for a fixed location wind turbine.
34. These vessels could be fossil fuel free by using the electricity
from the turbines and the hydrogen energy to power all of the on-board
systems.
