Project overview

Project period: FY2008 to FY2022, FY2019 budget: JPY 5.41 billion
Research and development item (1) PL: ISHIHARA Takeshi (Professor, Graduate School of Engineering, University of Tokyo)
Research and development item (2) PL: SUGURO Yukio (Representative Member, Japan Wind Energy Association)

 Compared to other types of renewable energy, wind power generation has lower power generation costs, and large-scale introduction of wind power is expected in the medium to long term. However—given Japan's harsh weather conditions—in order to implement long-term, stable wind power generation projects, it is necessary to further reduce power generation costs by improving the reliability of wind turbines as well as developing technology to improve power generation efficiency and enhance maintenance. In addition, given the expansion of the offshore wind power generation market both within and outside Japan, enhancing industrial competitiveness is becoming an important issue.

 Regarding wind power generation costs, although differences in facility utilization rates are an issue, Japan's capital costs as well as its operating and maintenance costs are higher than those of other countries.
Regarding offshore wind power generation in particular, because Europe—which leads the way in this field—differs from Japan in terms of its climate and sea conditions as well as its infrastructure (e.g., ships), technical issues and high installation costs have caused its introduction to stagnate.Regarding wind power generation costs, although differences in facility utilization rates are an issue, Japan's capital costs as well as its operating and maintenance costs are higher than those of other countries.

 Therefore, the goal of this project is to overcome Japan's issues related to wind power generation by developing innovative technologies that contribute to further cost reductions and thereby increase wind power introduction and promote enhanced industrial competitiveness. Guidelines on introducing offshore wind power will be prepared in relation to the installation, operation, and maintenance of wind turbines in order to expand offshore wind power. In addition, this project aims to facilitate efforts to develop construction technology that reduces the costs of fixed-bottom offshore wind turbines and therefore steadily and rapidly increase the introduction of offshore wind power in Japan.

 This project also strives to reduce power generation costs by developing technologies aimed at reducing the downtime as well as the operating and maintenance costs of wind turbines in Japan and by further increasing their energy production.
