The earth quarke caused nuclear disaster in Fukushima early this year, Japanese start to rethink energy source, now they come out with brand new solution for it, developing floating wind turbine in the deepwater.
It aims to outpace the leaders in the sector in Europe, trade ministry official Masanori Sato said on Tuesday.
In the next five years, Japan plans to spend 10 to 20 billion yen to install six or more floating turbines off the northeast coast. It will work with firms including Mitsubishi Heavy Industries and Fuji Heavy Industries for the relative machinery.
Globally, Norway leads the way on floating turbines with a 2009 pilot project while other countries including Britain and Portugal have studied the technology.
Japan is compiling a third emergency budget likely to be more than 10 trillion yen to rebuild its northeastern coast after the earthquake and tsunami hit in March; Leaving 20,000 dead or missing and triggering the world's worst nuclear crisis in 25 years at Fukushima Daiichi nuclear power plant.
Japan, one of the world's biggest greenhouse gas emitters, has been studying whether it can install conventional offshore wind turbines in an effort to cut its carbon emissions but thinks floated turbines could suit its waters better.
After the initial five-year programme, the trade ministry hopes to develop as early as 2020 an offshore wind farm off the northeastern coast with the capacity of about 1,000 Megawatts; But its success depends on the profitability of floating turbines as well as winning over local fishermen.
Wind power accounts for less than 1%of Japan's power demand. A government panel is set to start reviewing as early as this month Japan's energy targets, it had aimed to boost nuclear capacity to meet over half of power demand by 2030 by building 13 new reactors.
