The Japanese government has announced the intention to maximize the adoption of renewable energy sources as part of the nation's commitment to achieving carbon neutrality by 2050. Offshore wind power, in particular, is considered a vital part of the initiative to make renewables a primary source of power due to the potential for large-scale installation, lower cost, and economic ripple effects. In Japan, with limited shallow sea areas, there is growing interest in floating offshore wind power because it can be deployed in deep water. To promote the widespread adoption, it is essential to significantly reduce costs through technological development. In addition, increasing the ratio of domestic production (in Japan) is expected to create a strong economic ripple effect.
Against this backdrop, the five partnering companies in this demonstration project will jointly develop a small-scale (20kW) next-generation experimental floating axis wind turbine that is expected to reduce costs and increase the domestic production ratio.
The floating axis wind turbine (FAWT) is a concept under which a vertical-axis wind turbine is supported by a "rotating" cylindrical floating foundation. Its main features are as follows:
Cost Reduction
Increase in Domestic Production Ratio
J-POWER, Osaka University's Graduate School of Engineering and Albatross are jointly conducting initial studies of the FAWT concept. Embarking on the tests signifies the next step under a new framework. For the project, small-scale experimental versions of the FAWT will be installed in Japanese waters. After confirming the validity of the analysis and design method, this will lead to an even larger scale (megawatt class) offshore demonstration project.
The five companies involved in the project will use their individual expertise to jointly develop the FAWT, which is anticipated to be a "game changer" in floating offshore wind power generation. Through this collaboration, we aim to make offshore wind power generation the primary source of electricity and contribute to the realization of a carbon-neutral society.
Goals of participating companies:
J-POWER, TEPCO HD, Chubu Electric |
To develop promising technologies for floating offshore wind power generation and increase the introduction of renewable energy, thereby contributing to the realization of a carbon-neutral society. |
"K" LINE | As Japan's Ship Safety Act applies to floating offshore wind turbines, "K" LINE will cooperate in the practical implementation of new floating offshore wind turbines by providing its expertise, and contribute to a decarbonized society by applying the knowledge gained from this research in activities for offshore wind support vessels in the future. |
Albatross | To practically implement innovative floating offshore wind turbines and widely extend their use both in Japan and internationally. |
Cooperating Organizations
The wind turbine section of the small-scale experimental units will be developed by Fukui Fibertech Co., Ltd. (Aichi Prefecture), and the floating section will be developed by Mirai Ships Inc. (Miyagi Prefecture). The carbon composite material molding technology will be developed in partnership with the Innovative Composite Center (ICC) at the Kanazawa Institute of Technology, and the motion analysis technology will be developed in partnership with Osaka University's Graduate School of Engineering.
