“…Many researchers have integrated hydraulic transmission technology into offshor wind turbines to reduce system complexity and improve energy transmission efficienc A typical mechanical-hydraulic wind energy conversion scheme is shown in Figure These systems first convert wind energy into mechanical energy, and then convert th mechanical energy into hydraulic energy. Although mechanical-hydraulic wind energ conversion schemes have not been implemented in commercial hybrid wind-wave sy tems, they offer significant advantages such as stepless speed regulation, a high powe to-weight ratio, flexible transmission, and low maintenance costs [79,80].

Based on the mutual compensation of offshore wind energy and wave energy, a hybrid wind–wave power generation system can provide a highly cost-effective solution to the increasing demands for offshore power. To provide comprehensive guidance for future research, this study reviews the energy conversion and coupling technologies of existing hybrid Wind–wave power generation systems which have not been reported in previous publications. The working principles of various wind and wave energy conversion technologies are summarised in detail. In addition, existing energy coupling technologies are specifically classified and described. All aforementioned technologies are comprehensively compared and discussed. Technological gaps are highlighted, and future development forecasts are proposed. It is found that the integration of hydraulic wind turbines and oscillating wave energy converters is the most promising choice for hybrid wind–wave power extraction. DC and hydraulic coupling are expected to become mainstream energy coupling schemes in the future. Currently, the main technological gaps include short their operating life, low energy production, limited economic viability, and the scarcity of theoretical research and experimental tests. The field offers significant opportunities for expansion and innovation.
