No. 80: Power generation that utilizes wind and tidal current together (May 20, 2013)

Technology:
MODEC will start the substantiative experiment of a floating generator that generates electricity with the help of wind and tidal current together this fall. The floating generator is moored at the seabed with the chain. The floating structure is about 30 m in diameter. It has a windmill with the vertical rotation axis on the sea surface and a rotating waterwheel that rotates receiving tidal current under the sea surface. The windmill is 47 m high, while the waterwheel is 16 m downward from the sea surface. The generator has a generation capacity of 500 kW. The power generation technology that utilizes wind and tidal current was developed for the first time in the world.

The company is scheduled to finish installation toward the end of this August and start power generation this fall. In 2014, it plans to sell electricity to the local electric power company. It wishes to lease the generator to local fishers. Although an agreement with fishers on the installation, it strenuously looks for ways of coexistence with them. The project is funded by New Energy and Industrial Technology Organization (NEDO). Please click here for further details of this power generation system.
