Progress in the Development and Utilization of Wave Energy Technology Abroad

Ocean wave energy belongs to ocean surface energy- the kinetic energy and potential energy. It isa kind of clean, non-polluting, renewable new energy which has the advantage of high energy density and widedistribution. This article describes the working principle and application of several major wave energy devices（oscillating water column, tilting, raft, canard, oscillating buoy） and elaborates the wave energy technology trend.Based on the existing research and development, the paper studies the new technology, the new or modifiedsources in wave energy technology. Besides, this paper reveals three key issues of wave energy development andutilization technology （power generation efficiency and stability, survival and reliability, cost） and puts forwardthe corresponding solving methods. At last, it summarizes that the development trend of wave energy power generationtechnology is in the direction of high efficiency, high reliabilityand low cost. The research trend is to developnew principles or improved wave power generation technology, and consider other integrated energy powergeneration technology and comprehensive utilization, energy application and development from the nearshore applicationto the deep sea application.
