Progress of Generating Technologies on Oceanic Wave Energy

Oceanic wave power has drawn wide attention in the field of oceanic energy utilization around the world due to its giant reserves and clean renewable energy. The utilization technologies of wave power have tended to be mature, and are running into or near commercial exploitation level. This paper fully summarizes the basic principle of wave power utilization technologies, especially its multiple energy conversion system. The status of oceanic wave energy conversion technologies and main oceanic wave generating devices around the world are presented. Furthermore, the research and application progress of oceanic wave power generating technologies are illustrated in detail. After all, from the trends and broad prospects, the utilization of wave power is of great importance for the exploitation of oceanic resources in the littorals. It is also vital for the development of islands far away from continents, as well as essential for the combination wave energy and other marine energy resources.
