Chala et al.
The utilization of renewable energy sources has significantly increased in the last decade to combat the dire impact of fossil fuel emissions and sustain green energy sources in the future. Consequently, various renewable energy sources have been considered for energy production to fulfill the growing energy demands. In this modern era, technologies with the capacity of generating electricity…

Technological development is rarely a direct or swift path. Planned technological development must also progress in parallel with non-technical and practical development. This paper will present the developmental pathways that may lay ahead for Wave Dragon and the technical challenges in realising the full potential of this technology.

McNaughton et al.
This paper reports on experiments on a pseudo four tidal stream turbine array. This was achieved by towing two side-by-side turbines adjacent to the sidewall of a tow tank, which acted as a symmetry plane. The 1.2 m diameter (d) rotors were tested with d/4 tip-to-tip spacing at SSPA in Sweden through the MaRINET2 Transnational Access Programme. Tests at different tow speeds demonstrated that…

Renewable energies are those derived from the natural resources. Their availability and ability to replenish cause less damage to the environment and generate low CO2 emission made them evolve as one of the important sources of energy all over the world. Their benefits also include the savings in economy and their being environment friendly. Ports are important part of a nation’s…

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…

When conducting tidal energy resource characterization and assessment, it is important to capture the strong variations of tidal currents in time and space. Field measurements can quantify many of these variations, which have both deterministic and stochastic components. The deterministic components occur on timescales of hours to years. As such, they are repeatable and well-suited to harmonic…

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-…

Blanco et al.
This chapter is focused on Power Take-Off (PTO) systems for wave energy converters (WEC), being one of the most important elements since PTOs are responsible to transform the mechanical power captured from the waves into electricity. It presents Direct-Drive PTO (DDPTO) as one of the most reliable solutions to be adapted to…

A submerged tension-leg-platform for offshore wind turbine combined with a heaving type point absorber wave energy converter is analysed considering different configurations of array of wave energy converters. A time domain simulation is performed for the combined platform using fully coupled aero-hydro-servo-elastic simulation. The analysis is performed to study the effect of different…

The objective of this paper is to present the experimental methodologies and challenges of testing a wave energy converter array, concentrically attached to a semisubmersible platform, and in presence of wind thrust forces and moments. The tower of a wind turbine has been placed in the center of the platform and connected to a mass-pulley system through a light weight cable to simulate the…

Wave-structure interaction is an important topic concerning the modelling and performance optimization of Wave Energy Converters (WECs) operating in nearshore and coastal areas. In this work a BEM is developed and applied to the investigation of variable bathymetry (bottom slope and curvature) effects on the performance of surge-type wave energy converters excited by harmonic monochromatic…

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…

Different types of energy which generally fulfill the requirements of computing are mostly from thermal, mechanical, solar, wind, acoustic, and wave. Typically, IoT devices are powered by batteries that have limited lifetime, and thus these IoT devices need to be self-powered or require supportive energy sources that uninterruptedly power IoT devices. Energy harvesting is one of the techniques…

The ocean is a gigantic source of renewable and predictable green energy. The ocean alone can provide around 10 TW of energy to the total world energy demand. The ocean energy, in general, and the wave energy, in particular, has gained the attention of researchers because of its huge potential in the past few decades. In most cases, the output power of a single wave energy conversion (WEC)…

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.…

Water scarcity as a result of increasing population and limited fresh water sources, especially in certain part of the world, have developed an increasing demand for the seawater desalination. Among various desalination techniques, seawater reverse osmosis (SWRO) has become the most sought for technology due to its lower energy consumption over conventional distillation techniques, including…

Reverse electrodialysis technology has grown significantly in the last decade, gaining a fast increase in its technology readiness level and presenting some interesting examples of pilot systems operating under very different real environments. Among these, one was able to operate in a saltwork in Marsala (Sicily, Italy) with real concentrated brine and real saline waters (i.e., either…

Membrane desalination helps in responding to increasing freshwater (FW) global demand. Energy requirements of desalination technologies compromise its environmental sustainability. The integration of renewable energies might improve the sustainability of desalinated water over other alternative FW sources. This chapter discusses the sustainability of electrodialysis (ED) powered by…

Pressure retarded osmosis (PRO) and reverse electrodialysis (RED) have been studied recently for their potential in salinity gradient energy generation, the Gibbs energy harvestable when solutions of different concentrations are mixed. Polymer-based membranes are key components of these systems and therefore, the properties of these membranes largely determine the performance and applicability…

This chapter describes the utilization of underwater acoustic models for the evaluation of marine-system noise impacts associated with the installation and operation of marine-hydrokinetic energy (MHK) devices, particularly in coastal oceans. Coastal environments are generally characterized by high spatial and temporal variabilities, which make them very complex acoustic environments.…
