Abstract

Based on the global high-resolution wave reanalysis data that has assimilated the significant wave height of the satellite altimeters over the past 30 years, the wave energy distribution characteristics are analyzed in detail. Aiming at the developability of ocean waves, a new method for location evaluation of wave energy resources is proposed and use this evaluation method to divide the wave energy of the global and offshore China. The main conclusions are as follows： westerlies have the most abundant wave energy resources, accounting for 67% of the total global wave energy resources. Among them, the coastal wave energy resources are most abundant in the Indian Ocean westerlies, with an average wave power density of 90 kW/m, and the extent of wave energy utilization in the coastal westerlies are high. The wave energy of the China adjacent seas is relatively scarce, but the southeastern part of Taiwan Island, the Ryukyu Islands and the Dongsha Islands are slightly high in wave energy resources and have a high degree of availability, with an average wave power density of up to 11 kW/m. This research can provide reference for wave energy development planning and utilization.
