Researchers at Kyushu University in Japan are developing a large-scale at-sea power plant combining photovoltaics and windmills designed to match the output of a nuclear power reactor.
The planned plant will measure two kilometers by 800 meters and will be equipped with light-emitting diodes that shine light into the sea to promote seaweed growth, which in turn will absorb carbon dioxide and attract fish. The plant will comprise hexagonal floating units that support a length of netting on which wind-power generators and photovoltaic generators measuring six square meters will be placed.
About 200,000 photovoltaic generator units are to be placed about a meter apart on the netting, with the hexagonal units positioned at both ends. The units have a channel running through them to allow seawater to pass through. Each group of units will generate about 300,000 kilowatts of electricity, which means the generating capacity of the three planned sets will be equal to that of a nuclear power reactor.
The researchers project that the cost-to-power generation rate of the plant is between ¥70,000 to ¥140,000 per kW (US$643-US$1,287), compared to the ¥200,000 per kW (US$1,838) for constructing a nuclear power plant.
