“…There are many practical applications by using a power from marine renewable energy with positive advantages of green energy, nongas emissions, and saving environment. The outstanding characteristics of marine renewable energy lead to attentions of research groups such as applying in the power grid system [6], powering distributed sensors by power from ocean current energy conversion device [28], supplying the power for ocean robot by marine renewable energy [29], applying in the shipping industry with a hybrid energy model of renewable energy and fuel cell energy [30], developing electric power supply for remote area in the ocean by using the marine energy generator [31], supplying the power for an island by the marine renewable energy system [32]. Figure 3 shows some applications of marine renewable energy and some others renewable energy in the strategies of powering energy for remote communities [33].…”

Renewable energy is a sustainable and green energy converted from renewable energy resources in the nature. There is a huge amount of renewable energy resources in the ocean that can be changed into useful energy like electricity, store for long time use, or apply in the daily energy consumption. These marine renewable energies (MRE) include wave energy, ocean thermal energy, tidal energy, ocean current energy, salinity gradient energy, and offshore energy. With a big area, the oceans have been prospected that it brings endless renewable energy sources for social development and human demand. The renewable ocean energy shows many advantages of sustainable energy, clean energy, and non-carbon dioxide emissions by generating from wave and water in the ocean with an enormous amount of natural energy resources. The MRE can service at many areas of off-shore, on-shore, and remote areas where need energy to drive daily living demands. The MRE reveals some disadvantages such as the influence of daily, monthly, season, and period of time. The solutions have been developed to solve the limitations of the MRE such as developing the storage method to store energy for long time use or making the balance of the output performance to improve quality of the renewable energy. The MRE has also received many concerns from countries by promulgating policies, strategies, and plans to develop the renewable ocean energy such as green economy development, blue economy strategy, carbon dioxide emission reduction, and encouragement of using marine renewable energy. This paper reviews current marine renewable energy with its generation, storage, and application. The work also mentioned some advantages, disadvantage, policies, strategies, and solutions to encourage the development of the renewable ocean energy in over the world. The results hope that it will be spread development, exploitation, and application of marine renewable energy in the near future. Keywords: Marine renewable energy, energy storage, generation, application, sustainable energy

“…Galen et al conducted theoretical investigation to estimate harvesting potential from ocean waves. Authors concluded that a meter scale device can generate 1-10 W of electric power for waves with 0.2 m/s or slower velocity [9]. Wang et al designed WEC to deliver peak voltage of 40 V from ocean waves of height 1.4 m at frequency of 0.22 Hz [10].…”

In this work, a novel design of an oscillating body-type Wave Energy Converter (WEC) is proposed with an efficiency of 48.73 %. Innovative features of the new design include the integration of Mechanical Motion Rectifier (MMR), Motion Regulator (MR), Energy Storage Element (ESE), and Electric Generator (EG) with the operation controlled by a microcontroller, limit switches, and linear actuator. Lab experiments conducted with a prototype ensured a peak voltage of 8.1 V and peak power of 4.3 W. Experimental and MATLAB theoretical simulation results demonstrated the average power of 55.2-148.3 mW for a wave height of 50-125 mm. In comparison to the conventional operation, where the electric generator is directly driven by wave motion, the proposed design will ensure higher peak power and better energy utilization characteristics of the generated voltage waveform. Simulation results are presented with the incorporation of non-circular gears that ensure modification of the voltage waveform for better energy utilization.
