The offshore energy resource could ultimately provide power
for much of the coastal population in the USA and northern Europe. The wind and
wave energy resource is immense and continues off the shore. There is
room, and energy resource, for literally thousands of turbines and wave
converters, all of which be largely invisible from shore depending on their
"Sway" floating turbines under development in
Floating wind turbines are now on the drawing board that can
be moored in 300 feet of water or more.
The potential for ocean renewable energy is really enormous
when transmission cables are not needed. Floating wind turbines far offshore
could generate power for hydrogen power generation on commercial ships anchored
nearby. Hydrogen tankers could be steadily steaming into port bringing clean
renewable fuel. There is no practical limit to the renewable energy that
can be generated from the ocean this way.
The picture below illustrates the opportunity. Offshore
wind turbines and wave converters (shown are the
Pelamis devices) can be
installed off the coast in suitable depths that cover hundreds of square miles,
where the seasonal wind and wave energy is among the highest in the world.
They can make hydrogen at sea on floating platforms, and the hydrogen can be
shipped into the nearest port. Such activity would be licensed by the
Minerals Management Service and is not proposed as part of the Company's
However the feasibility studies will consider this opportunity.
A northeast Pacific Ocean renewable energy
field exists off the coast of Washington state. There are at least 4 million square km of ocean space that could generate as much as 5 MW/km2. Capturing even
a small fraction of this energy would be the world's largest energy project -
and it's renewable forever.
