Evaluating the Potential Wave Energy Through Wave Spectrum Analysis: A Case Study on the North Coast of Taiwan

Taiwanese government addresses the goal of “net-zero carbon emissions by 2050,” it has recently focused on developing green energy. Due to its sustainability and abundance, marine energy has been particularly emphasized, especially wave energy. The solid northeast monsoons that blew to the northern coasts of Taiwan every winter provide ample wind and wave energy. However, the wave activity seems weak during summer except for Typhoon invasion periods. The predominant waves of typhoon-induced are swell, which poses potential damage risks to wave energy converters. This study selects Long Dong on the northern coast of Taiwan as the research area, with data from wave buoys set up by the Central Weather Administration. The results show that the wind wave energy during the monsoon period is greater than the non-monsoon period. There are several extreme surge wave energy during the non-monsoon period.
