“…The T/P verification result in this study is comparable with another study such as in the South China Sea by Chu et al (2004) with the correlation of 0.90, RMSE of 0.48 m and bias of 0.018 m in the similar year of present study verification. Additionally, the study of wave energy in the south coast of Java by Song and Mayerle (2018) shows the correlation with altimeter data of Jason-2 obtained by AVISO of 0.86 and 0.93, and RMSE of 0.25 and 0.23 m in the rainy season and dry season, respectively. Overall, the simulated data are generally sufficiently in agreement with the observational data and are within the acceptable limits for further analysis and discussion.…”

The past few decades have seen considerable interest in exploration and research of ocean wave energy as a potential energy substitute for fossil-based fuel. In this study, a Wavewatch III spectrum wave model was driven to simulate significant wave height spanning for a period of 25 years, from 1991 to 2015 on the west coast of the island of Sumatra. The 25-year-average of wave energy shows some noticeable hot spots in certain areas that have a value of significant wave height up to 2.33 m and a wave energy 67.29 kW/m. These hotspot occurrences have a similar pattern as statistics collected for the seasonal characteristics that are associated with tropical monsoons with the average value of wave energy reaching its peak in an easterly monsoon season up to 98.21 kW/m, and the lowest average value occurring in the westerly monsoon season, lasting from December to February, with a prevalent value of 10 kW/m. Additional statistical parameters of possible wave energy site selections were considered, such as Coefficient of Variance, Monthly Variability Index, Optimum Hotspot Identifier, Wave Development Index, and accessibility to find the ideal location for wave energy converter deployment. These statistics give insight into potential prospective points for ocean-wave energy harvesting. Eight hotspots were finally selected based on the afore-mentioned statistical considerations and were further analyzed through wave energy characterization and obtained energy calculation through Pelamis, Archimedes Wave Swing, and Wave Dragon Wave Energy Converter power matrices. Finally, inter-annual variability and particular extreme events are discussed.

“…Tidal energy generates power during the surge of ocean waters during high tide and low tide, in which the worlds' first tidal power plant was opened in 1966 at Brittany, France [6], making this technology as one of the well-established technologies in the renewable energy by the ocean wave field. Ocean thermal energy which was first initiated in the 1970s, utilizes the differences in water temperature between ocean surface water and deep ocean water to drive a turbine or generator which later on translated into energy harnessing at an exorbitant scale [7].…”

The ocean offers vast opportunities for unprecedented energy harvesting where most studies had concentrated on large scale energy harvesting from the ocean waves. However, there were minimal studies on low-scale energy harvesting. This study focuses on ambient, low-scale energy harvesting which theoretically can be used to power low energy consumption electrical appliances. The inherent characteristic of piezoelectric materials which can convert mechanical energy to electrical energy has created an alternative to generate energy from renewable sources including ocean waves. Initially, this study started with preliminary work which consisted of the development and testing of a lab scale piezoelectric energy harvester (PEH-1) which was tested along the beach area of Kuala Nerus, east coast of Malaysia. Results from PEH-1 had shown that the high tide produced more power level compared to low tide experiments. The findings from the first phase of this study served as a foundation study towards the development of an upscaled version of the PEH-1 in relation of mechanical and electronics, which was termed as PEH-2. Testing for PEH-2 was conducted in the coastal area of Pulau Bidong Laut, Kuala Nerus. Results from the second part of the study had shown that approximately almost 80% of the power harvested correlated linearly with wind speed, however after reaching 0.7W the peak dips down which was probably due to the instability of PEH-2 to be used in harsh open seas environment. This study had shown the feasibility of utilizing piezoelectric material to harvest low-scale power, however, several in-house modifications needed to be made for it to be fully functionable.
