Abstract:

The increasing demand for clean, sustainable energy sources has driven research into innovative technologies that minimize environmental impact while fulfilling global energy needs. This study investigates the viability of harnessing ocean wave motion as a sustainable electricity source. Wave energy, abundant across approximately 71% of the Earth's surface, presents a largely untapped potential. This work identifies their respective effectiveness, scalability, and environmental implications through a comparative analysis of various wave energy conversion methods—including oscillating water columns, point absorbers, and attenuators. Key findings reveal that point absorbers offer greater efficiency in energy capture while oscillating water columns demonstrate superior environmental compatibility. Challenges such as geographical variability of wave resources, irregular wave patterns, and grid integration complexities are highlighted as critical factors for practical deployment. Overall, the study confirms that ocean wave energy holds significant promise as a renewable resource, provided that technological and infrastructural hurdles are addressed. This paper comprehensively reviews ocean vertical wave motion-based electricity generation, examining primary wave energy converter (WEC) technologies such as oscillating water columns, point absorbers, and attenuators. Key findings highlight the transverse flux permanent magnet generator's superior performance, potential power outputs of up to 90% operational time, and ecological benefits. The paper outlines selection criteria for WECs' comparative generator performance and proposes future directions for hybrid integration and optimized control strategies.
