As a promising renewable energy resource, wave energy is having more and more interest in both academic
research and industry development. In this paper, all subcategories of WECs are presented and discussed with their main
feathers. Although there are numerous subcategories of wave energy converter (WEC), wave energy exploitation still
haven’t reached its commercial stage. Many specific reasons and disadvantages limit its development. To overcome the
disadvantages and improve overall performance of WEC, a hybrid concept combining WEC and floating wind turbine is
proposed. The specific application of WEC in this hybrid system is also analyzed.
