Fukushima Floating Offshore Wind Turbine Starts Generating Power

mdsolar writes in with news about a new wind-energy project off the coast of Fukushima. "A project to harness the power of the wind about 20 kilometers (12 miles) off the coast of Fukushima, site of the March 2011 nuclear disaster, began generating power on an operational basis today. The project, funded by the government and led by Marubeni Corp. (8002), is a symbol of Japan's ambition to commercialize the unproven technology of floating offshore wind power and its plan to turn quake-ravaged Fukushima into a clean energy hub. 'Fukushima is making a stride toward the future step by step,' Yuhei Sato, governor of Fukushima, said today at a ceremony in Fukushima marking the project's initiation. 'Floating offshore wind is a symbol of such a future.'"

You have a "dead zone" where there is little wind and above you have a much higher flow of wind, which can only lead to the wind above pushing down over some distance from the wind farm to fill the void and dumping down inland (because if you put the things too far out you would need really long cables).

The efficiency trade off is between getting good use from the turbines (say 0.8 capacity factor) and taking a hit on the charge cycle efficiency which looks pretty good for a battery. For producing liquid fuels, it is more a matter of economics. Liquid fuels are not used efficiently but they are convenient. The Navy claims a $3-$6 cost per gallon using their rather expensive nuclear reactors. High capacity factor wind, even offshore, should be less expensive.

The idea of churning these puppies out is extremely optimistic Let's say they can make and install one of these monsters a month. To match the nuclear plants output would only take 48 years. Even if it takes 10 years for a reactor you could have 5 plants in operation in that time. Now think about world wide production. Factories that can make something like this will be limited in number. Just shipping the blades will be a huge task. Then the infrastructure of floating wind farms and the under sea power cables and maintaing the wind turbines in a marine environment. This is not as easy you may think and it is not because it is "new" but because of well known problems that intrinsic to the system.

    Both the disadvantage and advantage of wind turbines is the small unit size. If one goes down it's no big deal. If you need another 2MW as the peak ramps up you just bring another one online instead of having it as spinning reserve. Maintanance schedules for wind turbines are short, but once again, since they are so small having a few down doesn't matter.
    There's no point comparing them to thermal power since they are a "flexible" peak load power source that is really competing with quite expensive per watt stuff that is effectively jet engines running on natural gas - little stuff that can be brought on line in under a minute. The other is relatively remote areas off the main grid where the local power may well be diesel - once fuel shipping costs go beyond a certain point it hardly matters how expensive the wind turbines are.
