Majumdar et al.
India being a tropical country, has a large ocean thermal gradient available throughout the year that can be utilized to extract energy. This energy can be used to power a Low-temperature thermal desalination (LTTD) plant using the Ocean Thermal Energy Conversion (OTEC) method. OTEC works at a very low pressure, and developing a low-pressure turbine for OTEC is very challenging. The turbine…

Marine renewable energy (MRE) is arguably the most underdeveloped form of renewable energy. However, its estimated potential as a renewable energy source is only next to solar energy, and hence, it can replace the existing fossil-based energy sources. Five different forms of MRE, viz., tidal barrage, tidal and ocean currents, wave power, ocean thermal energy conversion (OTEC), and salinity…

The chapter describes the geological and legal aspects of the continental margin, including its marine resources, of the Bay of Bengal, especially its northern part adjacent to Bangladesh. The maximum width of the continental shelf is 216 km (117 nm, nautical miles) from the Bangladesh coastal plain. On the contrary, court verdicts have given Bangladesh entitlement to 118,813 sq km of sea area…

Ocean thermal energy conversion (OTEC ) utilizes the thermal gradient available in the ocean to operate a heat engine to produce work output. Even though the concept is simple and old for almost one century, during last three decades, it has gained momentum due to worldwide search for a clean, continuous energy source to replace the fossil fuels. There are technological hurdles to overcome to…

Lee et al.
The ocean thermal energy conversion (OTEC) plant is designed to improve the efficiency of the existing plants. Various researches are being conducted to increase the plant’s efficiency and output with the use of an enhancer, and studies for performance improvement are also in progress from the Kalina and Uehara cycles to ejector pump OTEC (EP-OTEC). Their performance can be improved by…

Acevedo et al.
In this chapter, we present the methodology for the selection of the working fluid, the environmental and working conditions for operation, and the development carried out for the design of a closed cycle OTEC prototype plant. This prototype uses the temperature difference between the cooler deep waters and the warmer surface waters of the Mexican Caribbean Sea to feed a thermal machine…

Jaafar et al.
The search for potential investors in the conversion of ocean thermal energy to power or hydrogen, and its spinoff projects in Malaysia and the region, continues. In the meantime, several pre-feasibility studies have been completed for selected sites, including that of Pulau Layang-Layang and Pulau Kalumpang (Sabah, Malaysia); Timor-Leste, and off Pulau Weh (Aceh, Indonesia). Various research…

Liu et al.
This chapter mainly introduces the development and prospect of turbines utilized in ocean thermal energy conversion (OTEC), including brief introduction, aerodynamic design, mechanical and electric control system, problems, and prospect of the turbine in OTEC. At the beginning, the first section mainly introduces compositions and types of turbine in OTEC systems, different working fluids in…

Huante et al.
The purpose of this chapter is to provide an assessment of the resource potential for ocean thermal energy conversion (OTEC) in the Mexican Pacific Ocean (MPO). Research methodology adopted in this study is a combination of geographic information system (GIS), to identify the most promising site in the MPO for OTEC deployment. Site selection criteria rely on conditions such as distance to cold…

The deployment of a land-based Ocean Thermal Energy Conversion (OTEC) plant in South Tarawa, Kiribati, Pacific Islands Region, in 2020/2021, represents a major technical achievement, alongside an international development opportunity. Pacific Small Island Developing States (PSIDS) are archipelago nations with small land areas and large oceanic exclusive economic zones. Geographical isolation…

The energy supply sector is the largest contributor to global greenhouse gas emissions. The ocean offers many options for reducing greenhouse gas, particularly through the development of renewable energy technologies. However, although the ocean holds vast amounts of energy, it is drastically underdeveloped. In this chapter, the nature and key aspects of these ocean renewable energy options…

The chapter explores the origins of ocean power, the three types of energy captured from the oceans, the energy from the motion of the waves, the energy from the tides, and from using temperature gradient in oceans. The main onshore and offshore ocean wave technologies are described. Tidal origins, fundamentals, and power-…

Mathew et al.
Biofouling is a major problem that affects the heat transfer efficiency of marine and coastal heat exchangers. The reduced heat exchanger efficiency results in energy loss and thereby affects the overall energy efficiency in the marine industry segment. Additional energy is required to compensate for the energy loss leading to increased fuel consumption which in turn contributes to global…

The vertical temperature distribution in the open ocean can be represented as two layers separated by an interface. The upper layer is warmed by the sun and mixed to depths of about 100 m by wave motion. The bottom layer consists of colder water formed at high latitudes. The interface or thermocline is sometimes marked by an abrupt change in temperature but more often the change is gradual.…

Daborn et al.
There should be little doubt that the world needs to diminish its dependence upon fossil fuels for electricity generation. Marine renewable energy (MRE), in the forms of offshore wind, tidal, wave, or ocean thermal energy, remains the largest under-exploited energy source, with the potential to supply more than the total electricity demand in the world. It is estimated that the…
