“…The MRE system may be customized to create a multi-output system, such as a wavedriven desalination system, that uses ORE resources to generate drinking water (W20 project, 2022), (WEC device using PTO system) (Nolan and Ringwood, 2006) and energy at the same time. Current research and development focus on systems combining ORE, power, and portable water production (Ferreira and Estefen, 2011;Leijon and Boström, 2018). Small islands and isolated places are typically not linked to the national grid and rely only on diesel generators for power.…”

This paper aims to comprehensively review the economic feasibility of Marine Renewable Energy. Five major continents are at different development stages of implementing MREs commercialization; Europe is in the most advanced, while Africa is at the initial stage. The Levelized Cost of Energy is usually used to make decisions and measure the plant’s economic feasibility. Literature suggests that MRE technology is still costly, and many emerging countries are sensitive to the income and use of MRE. Among various types of MREs, wind energy is the most feasible for many countries. Offshore wave energy is still at the pre-commercialization stage for many developing countries. Tidal energy plants can be economically viable depending on a reduction in investment cost and high capacity factors. Most of the world’s tidal flows have too low a speed to operate a turbine of commercial size for ocean thermal energy. In conclusion, the factors hindering MRE development are pointed out, and future challenges are discussed.

Ocean energy represented by waves is considered as a one of the renewable energy sources. This study aims to evaluate the methods that enhancing the ocean wave energy convertor performance. The mechanism of wave energy convertor is by converting mechanical energy to an electricity energy using DC generator and running by the pulling of wire due to ocean wave movement. Moreover, the test and analyze of converting the wave energy to electricity are conducted. Firstly, the role of numerical modeling lies in fabricating the tested rig in addition to study and analyze the buoyancy and stability in fluid mechanics as results of converting the kinetic energy derived from sea waves into rotational energy. The experimental tests were achieved locally at the Arabic gulf-South of Iraq/Basra (Khor Alzubayr). the tests were performed in two cases named: after happening the tidal (tested in one direction) and at the increasing of the sea water (tested in bidirectional). The results of local tests (at the sea) show that the maximum power of test was recorded value about 68 W in case of happening the tidal with an increase percentage of 92.6% over the case of bidirectional. These findings encouraging for more investigation in the methods that could increase energy harvesting from ocean waves since it is an enormous amount of energy.

“…In recent years, several kinds of ocean power converter prototypes have been developed, according to the expertise of each inventing team and or specific issues from the local sea where it was designated [9][10][11][12][13][14]. These large numbers of prototypes and concepts indicated that the most suitable technology has not been defined to be applied for commercial purposes [9].…”

This paper presents the results from experimental validation of numerical simulation of a concept wave energy converter for low amplitude sea waves. The device was conceived to contain a wave amplifying device (WAD) to magnify the wave height of incident waves while point absorber buoy(s) efficiently harness the wave energy for electricity production. The validation results show that the optimum aperture angle for the WAD is 45±2 degree, and wave height magnification of 170% is possible. The optimal buoy shape for the device was confirmed as concave wedge buoy. The combination of the two in a single device shall make economical the harnessing of low amplitude waves.
