There are two types of ocean power that can be harnessed: wave power and tidal power. Wave power is associated with the energy produced by ocean waves that are on the surface and converting that energy for the generation of electricity. Today, wave farms have been installed in Europe. Currently, this type of renewable does not have significant penetration, because it is highly unreliable, and it requires large wave energy converter to be deployed. The first such farms are expected to be a wave park in Reedsport, Oregon, and the Perth wave energy project in Western Australia. The PowerBuoy technology that will be used for this project will have modular, ocean-going buoys, and the rising and falling of the waves will cause the buoys to move, creating mechanical energy that will be later converted to electric energy and transmitted offshore through the underwater transmission line.

The predictability of power generation from renewable sources, such as wind, wave or solar, is an important factor for the energy sector that helps to manage the grid load and imbalances in the electrical system. Data has shown that it is possible to achieve an accurate wave forecast for 36 hours, while wind speed and directionality can only be predicted accurately 12 hours in advance [66]. Other research demonstrates that the output from WECs is up to 35% more predictable than power generated from wind turbines [127]. In summary, wave power has been shown to be more available, less variable and more predictable than wind or solar energy.
A simple SPH model of a free surface water wave pump: waves above a submerged plate

Ocean waves represent a tremendous source of renewable energy with an estimated 2TW wave power capacity reaching the world coastlines (Gunn and Stock-Williams 2012; Reguero, Losada, and Méndez 2015). Yet, the current state-of-the-art makes it the most expensive form of energy (Tollefson 2014; Saincher and Banerjee 2016). As a consequence, there is a growing interest in new concepts of wave energy converter devices (WECs) and mean to design and test their efficiency. In this paper, we propose to use the smoothed particle hydrodynamics (SPH) method to study a peculiar kind of WEC: waves above a submerged plate (WASP) pump. The SPH method is a Lagrangian method particularly useful in solving problems with large surface deformations as encountered in coastal and ocean engineering applications (Gotoh and Khayyer 2018).
Review and assessment of offshore renewable energy resources in morocco’ coastline
Published in Cogent Engineering, 2019
Wave energy is formed by wind combined with the atmosphere’s redistribution of solar energy. Waves are established over oceanic distances to energy densities averaging over 100_kW/m, as wave energy is typically measured in power per meter width of wave front (Barstow, Mollison, & Cruz, 2008). The same source assessed some major advantages of this offshore renewable energy resource; it has a high quality form, i.e. mechanical energy of oscillation, and that it travels long distances with slight loss, so that slight inputs over a large ocean can accumulate and be collected at or near the ocean’s edge. Moreover, wave power at a well suited site is available up to 90 percent of the time, while solar and wind availability tend to be available just about 20–30 percent of the time (Power buoys: electricity from waves, 2001). Further advantages comprise the point absorber effect, in which the devices can extract energy from a portion of a wavelength on either side; this possibility makes small devices with capacities of the order of 1_MW (Barstow et al., 2008). Other researchers, such as in (Falnes, 2002; Mork, Barstow, Kabuth, & Pontes, 2010), estimated that the global power resource to be in the order of 3.5_TW.
