Japan will join the race to develop floating wind turbines to use in deepwater off its tsunami-stricken northern Pacific coast as it rethinks energy sources after the Fukushima nuclear disaster.
It aims to outpace the leaders in the sector in Europe, trade ministry official Masanori Sato said on Tuesday.
“In order to take lead in offshore wind power, we want domestic studies and developments to take place and manufacturers to boost capabilities,” said Sato.
“From the viewpoint of supporting reconstruction and promoting wind power, we believe it is good to pursue research and development for offshore wind farms,” he said.
In the next five years, Japan plans to spend 10 to 20 billion yen ($130 to $260 million) to install six or more floating turbines off the northeast coast. It will work with firms including Mitsubishi Heavy Industries and Fuji Heavy Industries, Sato said.
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 ($130 billion) 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.
Last month its parliament enacted a bill to promote investment in renewables.
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, said Hiroyuki Iijima, another official at the trade ministry.
But its success depends on the profitability of floating turbines as well as winning over local fishermen, Iijima added.
Wind power accounts for less than 1 percent 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.
Atomic power helped meet some 30 percent of Japan’s power prior to the quake. Only 11 out of 54 nuclear reactors are operating now as reactors halted for maintenance checks have been kept shut.

About This Story
Perhaps you noticed: This story, like all the news we publish, is free to read. That’s because Inside Climate News is a 501c3 nonprofit organization. We do not charge a subscription fee, lock our news behind a paywall, or clutter our website with ads. We make our news on climate and the environment freely available to you and anyone who wants it.
That’s not all. We also share our news for free with scores of other media organizations around the country. Many of them can’t afford to do environmental journalism of their own. We’ve built bureaus from coast to coast to report local stories, collaborate with local newsrooms and co-publish articles so that this vital work is shared as widely as possible.
Two of us launched ICN in 2007. Six years later we earned a Pulitzer Prize for National Reporting, and now we run the oldest and largest dedicated climate newsroom in the nation. We tell the story in all its complexity. We hold polluters accountable. We expose environmental injustice. We debunk misinformation. We scrutinize solutions and inspire action.
