Does Hokkaido have a wind farm?

There’s enough wind energy here for Japan’s northernmost island to power itself and export clean electricity to the rest of the country. But Hokkaido can’t harness all of that power unless it has a way to store energy when breezes are blowing and use it later when the gusts die down. A wind farm in the town of Setana on Japan's Hokkaido island.

Why do Hokkaido power plants use flow batteries?

Power lines running from the flow battery plant on Hokkaido. These batteries help Hokkaido keep a steady balance between the amount of energy its power plants generate and the amount of electricity its homes and businesses use.

Are wind turbines making a dent in energy production?

After decades of development, the world has figured out how to make wind turbines and solar panels cheaply and at massive scale. They’re starting to make a dent in energy production, accounting for 15 percent of electricity globally, according to the International Energy Agency.

Could new quinones and ferrocyanide power a flow battery?

A flow battery using the new quinones and ferrocyanide would likely only have to be the size of a couple of hot water tanks to store the energy produced by a conventional home rooftop solar array. "The chemistry sounds great," says David Keith, an energy expert at Harvard, who was not part of the current study.

How many wind turbines are there in Hokkaido?

The 14 turbines — each about 20 stories tall — face across the water from a natural gas plant that would shut down if Hokkaido’s clean energy plans succeed. Japan’s biggest offshore wind farm sits just off the coast of Ishikari, a seaside town on Hokkaido.

How do wind turbines work?

The towers would store electricity generated by renewables when their output is high in windy, sunny conditions and release energy back to the grid when production falls as winds die down and clouds move in.
