Orekan and Zhang
This chapter presents theoretical analysis of the Smart-WEC at different wave conditions (regular and irregular waves). The Smart-WEC is a new type of point absorber wave energy converter that stores energy from the waves and form a completely self-contained, persistent, energy source platform suitable for powering distributed ocean systems (e.g., AUV). Power generated is then transferred…

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…

Water’s natural flowing movements, such as in rivers and reservoirs, can be used in the production of electricity. Furthermore, both the tidal range (the periodic rise and fall of the sea level) and the energy contained in flow and waves can be used in the ocean energy system. Both types of energy conversion are classed as renewable energies. While the typical use of hydropower has been…

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…

This chapter presents the results of the investigations leading to the development and application of a general procedure for the characterization of tidal current energy resources in data-poor sites. It implements methods to identify suitable sites for tidal power extraction, estimate effective power potentials, and assess impacts of tidal turbine arrays on the environment. The process relies…

In this article, we present the numerical analysis performed on a compact mechanical-based direct drive wave energy converter (WEC), in order to improve its performance on longer wave periods. For this work, the numerical modeling of the point absorber is done with the help of an open-source code written in MATLAB, WEC-Sim and the hydrodynamic parameters of the WEC are determined using the BEM…

A Power Take-Off (PTO) is a core sub-system of a Wave Energy Converter (WEC) related to the conversion of wave to electrical power. The PTO is exposed to challenging environmental loading conditions that characterise wave energy. This paper investigates how the PTO developed by the UMBRAGROUP in the H2020 IMAGINE project could be considered for multiple WEC configurations. In particular, the…

Prior to installation and operation, the prefeasibility study of a tidal energy system is customarily carried out. The prefeasibility analysis includes the study of climatic conditions, longitude, latitude, a study of the coastal area, low and high tide and tidal current of the proposed site, and availability of tidal energy sources and assessment of its potential load and load demand of the…

This chapter presents an outline of the requirements for, and the benefits of, short term energy storage at the level of individual wave energy devices, in the field of ocean wave energy conversion. A general background introduction to ocean renewable energy from the perspective of industry growth and incentives, as well as an overview of the different technology types is provided. The unique…

Composite materials are the natural choice for the construction of tidal energy blades; their high strength, good environmental resistance and the ease with which they may be used to form complex shapes means that they are well suited to the application. The design of MW-scale tidal energy blades has evolved over a number of years, keeping step with the requirements of turbine developers as…

Jaksic et al.
The structural design of marine tidal turbine blades is governed by the hydrodynamic shape of the aerofoil, extreme loadings and composite material mechanical properties. The design of the aerofoil, chord and twist distribution along the blade is generated to optimise turbine performance over its life time. Structural design gives the optimal layout of composite laminae such that ultimate…

Harper et al.
This chapter discusses the applications and challenges for glass and carbon fibre composites in marine renewable energy devices. It uses a tidal turbine blade as a case study, describing the nature of the operating environment and resulting loads, the structural design process, material selection, manufacturing techniques and structural health monitoring. The chapter also discusses ongoing…

There exists a huge potential for the generation of energy from the mixing of saltwater and freshwater. The potential is 2.6 TW, which is more than the global electricity consumption (2.0 TW). Two membrane-based technologies exist to convert this potentially available energy into useful power: pressure-retarded osmosis (PRO) and reverse electrodialysis (RED). In PRO, water is transported…

Renewable Energy Resources (RES) play a critical role in electrical systems due to continuous demand increases. As a significant application of RES, modern electrical networks are very complex because of communication tools, smart meters, and real-time data processing. These smart tools and ongoing communication generate a high-speed tsunami of data that require novel methods for better…

Over the last decade, research on technologies to exploit tidal current kinetic energy for renewable electricity generation has had a significant growth. However, as to date, there is not a consensus worldwide on standard Power Take-Off (PTO) systems, due to the current immaturity of tidal energy converter technologies. In most cases, mechanical/electrical power conversion follows well-proven…

Marine hydrokinetic energy includes that due to waves, tides, and ocean currents. The characteristics of these forms of energy and the assessment of their potential for extraction are discussed briefly herein. Detailed consideration is given to the assessment of ocean current energy, including a case study of the resource assessment of the Florida Current. Estimates of global and local open…

Extraction of energy from ocean waves is a high-priority sustainable-energy initiative in the UK. The Offshore Wave Energy Ltd wave energy convertor (OWEL WEC) is a floating rectangular box which captures waves at one end and extracts their energy though a power take off (PTO) system at the other end. The Surrey team is providing underpinning modelling and mathematics to this project. The…

Ocean currents in tidal flows and at the western boundaries of the ocean basins, as well as currents in rivers, can have as much potential for power production as the wind. With increased interest in sources of renewable energy, realizing this potential has undergone a renaissance in recent years. This chapter provides an introduction to ocean current energy conversion by emphasizing the…
