Several Japanese firms, including Electric Power Development, Tokyo Electric Power, Chubu Electric, Kawasaki Kisen Kaisha, and Albatross Technology, have agreed to collaborate on the development of a next-generation floating axis offshore wind turbine demonstration project. To meet its pledge to attain carbon neutrality by 2050, the Japanese government is aiming for the widespread deployment of renewable energy. One of the most significant renewable energy sources has been discovered as offshore wind, but Japan’s restricted shallow water areas have impeded its development.
Offshore wind turbines that float and can be installed in deep waters are gaining popularity. However, cutting costs is essential to enabling its wide acceptance, and research and development are currently in progress. The local production of the facilities will also help the economy. Therefore, the companies intend to work together to create a small 20 kW experimental floating axis turbine. This is expected to reduce costs and increase domestic production. The concept uses a vertical-axis turbine supported by a rotating cylindrical floating foundation. At its maximum output, the turbine can be tilted 20 degrees, and it will still function well.
This is anticipated to enable downsizing and lower equipment costs. Continuous pultrusion, a molding technique that forms composite materials into long shapes, can produce the turbine component at a lower cost. Operational and upkeep costs can be greatly decreased by placing the vertical axis wind turbine close to sea level. There is no need for massive manufacturing facilities because the turbine blades can be produced in sections with the same cross-sectional form. Their layout makes them beneficial for domestic manufacture and promotes simple transit.
