Abstract

Based on NOAA WOA 2018 data set, the Nihous method was used to evaluate the ocean thermal energy conversion （OTEC） sources in the South China Sea, Xisha Islands and Yongxing Island from 2005 to 2017. In addition, the OTEC resources in Yongxing Island area from 1955 to 2017 was also assessed. Thereafter, the spatial and temporal variation characteristics of OTEC sources were analyzed. In order to meet the site selection requirements of power stations, the distribution of OTEC resources and water depth around Yongxing Island were analyzed specifically in detail, and eight potential power generation sites are selected. In terms of net power of OTEC, offshore distance and sea water depth, four relatively better sites were finally determined. The interannual variation and seasonal index variation of net power of ocean thermal energy generation at four sites were analyzed.
