Abstract
The purpose of this study is to compare different types of wave energy converters, Mega Roller, Pelamis P1, and Wave Dragon, which are categorized based on their multifreedom movements in oceans. Life-cycle costing is a method for the cradle-to-grave assessment of these technologies and also a way to minimize environmental impacts throughout the wave converter’s supply chain. Hence, several case studies, from Walker and Howell to Parker et al., Thomson et al., and Hans. Chr Sørensen et al., were considered and assessed based on carbon and energy intensity in this research.
