This document presents the revised draft of the research development and social implementation plan for the "Cost Reduction of Offshore Wind Power" project under the Green Innovation Fund program formulated by the Ministry of Economy, Trade and Industry, outlining specific implementation content and structure.
This revised draft was formulated as a more concrete and effective plan based on the latest technological trends and market environment indicated in July 2025. The project totals approximately 200 billion yen, promoting innovative technological development for offshore wind power through combined public and private investment.
Details of Research Development Items
The revised draft establishes four main research development items. First, next-generation wind turbine technology development includes blade enlargement and weight reduction, nacelle efficiency improvements, and optimal tower design. Second, floating foundation manufacturing and installation cost reduction technology development plans mass production technology, construction method innovation, and dynamic cable system development. Third is power conversion system efficiency improvement, and fourth is advanced operation and maintenance.
Implementation Structure and Role Allocation
Project implementation will form consortiums with participation from major heavy industry manufacturers, power companies, construction companies, and universities/research institutions. Each entity's roles are clarified, establishing an integrated structure from technology development through demonstration to commercialization. International collaboration is also emphasized, with technical cooperation with leading European companies included in the plan.
Stage Gate Evaluation and Progress Management
Project progress will be strictly evaluated at multiple stage gates. Decisions on continuation will be made from perspectives including technical achievement, cost reduction effects, and marketability, enabling flexible plan modifications. The first stage gate evaluation is scheduled for 2027, with the second evaluation in 2030, requiring target achievement at each stage.
Expected Results and Impact
Success of this project will establish internationally competitive offshore wind power technology by the early 2030s, enabling large-scale deployment domestically and internationally. Economic effects include market creation of approximately 5 trillion yen and employment creation of about 60,000 people. Additionally, CO2 reduction effects are estimated at approximately 50 million tons annually, expected to contribute significantly to Japan's decarbonization.
The article demonstrates that the offshore wind power cost reduction project has entered a concrete implementation phase, with efforts to strengthen the competitiveness of Japan's renewable energy industry in full swing.
