“…The most important part of the energy conversion in the wave generator is the generator, which converts the floating mechanical energy into electrical energy. Using Faraday's Law of Electromagnetic Induction, the linear movement of the magnet connected to the float in the fixed coil of the chamber produces electric power [43]. The anchor is fixed to the ocean floor by an anchor system.…”

This study proposes a data-driven methodology for modeling power and hydrogen generation of a sustainable energy converter. The wave and hydrogen production at different wave heights and wind speeds are predicted. Furthermore, this research emphasizes and encourages the possibility of extracting hydrogen from ocean waves. By using the extracted data from FLOW-3D software simulation and the experimental data from the special test in the ocean, the comparison analysis of two data-driven learning methods is conducted. The results show that the amount of hydrogen production is propor-tional to the amount of generated electrical power. The reliability of the proposed renewable energy converter is further discussed as a sustainable smart grid application.

“…Among all these types of marine energy, wave energy has drawn the greatest attention throughout the world. Significant advantages of wave energy compared to other types of renewable energies are predictability, availability, and relatively high energy density as well [28], which enables it to produce more power while consuming less budget [103]. Surface waves or pressure variation under the surface of water are responsible for wave energy generation.…”

“…In addition, multiple large projects are under construction in the UK [106]. Several studies have dealt with Iran's potential for wave energy [102][103][104][107][108][109][110][111][112][113]. A mediocre value of 6.1 kW/m was reported as wave energy potential for Persian Gulf, whereas, due to the close proximity to open waters of ocean, the Gulf of Oman is benefited from a greater potential of 12.6 kW/m [107].…”

Nowadays, fossil fuels are well known as a predominant source of energy in the planet. Located in the Middle East region, Iran holds one of the largest fossil fuel reservoirs in the world. The country has abundant oil and natural gas fields in various regions; some of them are shared between other countries and have not reached their operational capacity yet. Meanwhile, during recent years and due to global warming followed by environmental global contracts such as Kyoto protocol, using fossil fuels is being criticized to a large extent around the world. Therefore, the global interest has been focused toward clean energy resources. Furthermore, endowed with sundry geographical pattern throughout its land, Iran has adequate renewable energy potentials. So, there will be a serious paradox affecting its whole energy policy: more exploration and extraction of conventional fossil fuels or take advantage of renewable and sustainable energy resources? In this paper, energy structure of Iran is generally overviewed, followed by study of renewable energy potentials in various parts of the country. Afterwards, policy making in renewable energy market, systems, and applicable strategies are elaborated. Furthermore, a number of barriers obstructing the development path of renewable energy schemes and initiatives are presented and discussed in detail.

“…The parameters of an OWC wave energy conversion system include many aspects, such as the dimensional effects of the OWC structure, including both the size and shape of the structure, the associated turbine system and the environmental conditions of the location of the OWC system that may cover geology and wave conditions. As shown in a contemporary paper [14] describing a parametric study of a wave energy converter designed for the Caspian Sea, where a numerical simulation using the commercial software Flow-3D to model the motion of the energy converter for different wave heights was applied for output flow rates in different seasons, extractable wave power and output power, the parameters of an OWC conversion system are strongly related to location factors. Studies on the interactions for different wave periods, wave heights and pneumatic damping factors of OWCs were also performed lately [10,15].…”

“…There seems to be a trend where more and more countries have considered building OWC-like wave energy conversions system on their shorelines, especially in local harbors, as mentioned previously [14,16,19], but construction of an OWC wave energy conversion system usually costs a tremendous amount of money. A thorough study to avoid any uncertainty and safety risks prior to the construction is usually required besides any functioning considerations.…”

This study focuses on the analysis of the parameters of an oscillating water column (OWC) wave energy conversion system and wave conditions. Interactions between the dimensions of the OWC chambers and wave conditions are all taken into account to design an alternative OWC converter, called caisson-based OWC type wave energy converting system. A numerical method using an unsteady Navier-Stokes equations theorem in conservation form is used to analyze the proposed analytical model. The objective of this study is to try to apply an OWC wave energy converter to a caisson breakwater, which has been constructed in a harbor. The structure proposed in this study is a series of sets of independent systems, in which each set of converters is composed of three chambers to capture the wave energy, while better ensuring the safety of the caisson breakwater. Responses to be analyzed related to the conversion efficiency of the caisson-based OWC wave energy converting system include the airflow velocity from the air-chamber, the pneumatic power and the conversion efficiency in terms of a ratio between the pneumatic power and the energy of the incident waves. Parameters examined in this study include the dimensions of the OWC chamber features such as the orifice of the air-chamber allowing airflow in/output, the chamber length along the direction of incident waves, the size of the opening gate for incident waves and the submersion depth of the air-chamber. As found from the results, a best conversion efficiency from incident waves of 32% can be obtained for the extreme case where the orifice is very small, but for most other cases in the study, the best efficiency is about 15%.
