Abstract:Offshore wind energy resource is a key support for the “carbon peak and carbon neutrality”. However, offshore wind energy development still faces the international bottleneck of reasonable energy classification, which is urgently needed in the overall arrangement and accurate site selection. Firstly, this study systematically reviewed the research progress of offshore wind energy classification scheme at home and abroad, and analyzed the six aspects that need to be improved in the traditional energy classification scheme: without comprehensive consideration of resource characteristics, environmental risks and cost-effectiveness, without significant regional difference of energy classification, unable to meet the needs of diversified tasks, not applicable in some months, insufficient estimation of future energy classification, inconsistent with the mechanism. To deal with the above difficulties, the concept of wind energy classification which is all-factor, all-time, all-sea, and dynamic and adaptive is proposed. And it is also necessary to draw a dynamic map of wind energy classification, to solve the problems of overall strategic layout, accurate site selection, and long-term scientific planning for resource development, to accelerate the industrialization, scale, and independent high-quality construction, thus to contribute to the “carbon peak and carbon neutrality”.
