A huge effort is now under way to develop energy systems that make use of natural energy flows in the environment — including those produced by waves and tidal streams. Since the reduction of carbon emissions is a principal advantage of wave, tidal and other renewable technologies, one should recognise that this benefit is also proclaimed by supporters of nuclear power. This chapter considers…

This chapter presents a case study on tidal energy converters. It describes a number of devices at the forefront of development, many of which are being, or have been, tested at the European Marine Energy Centre (EMEC) in Orkney. The authors also raise a variety of practical issues that greatly affect device developers as they build, deploy and test devices which, in many cases, approach or…

This workshop looks at the opportunities and barriers to local adoption of ocean renewable energy in islands and remote coastal areas of the Asian region from the perspectives of various stakeholders and the possible solutions to address the challenges. It also tackles the crucial roles of the different stakeholders (academia, policy-makers, industry and end-users) that each has to play to…

This chapter aims to shed light on such alternating current (AC) curiosities as reactance and impedance, real and reactive power and power factor correction to introduce the operating principles of electrical generators and explains how modern electronic control eases the problem of converting unruly marine energy into the well‐behaved electricity required by an electricity grid. Finally, the…

This chapter talks about marine energy capturing. It introduces the physics of ocean waves and tidal streams as a prelude to explaining the principles underlying some of today's most promising developments. Wave measurement buoys are used by marine energy organisations to provide the continuous, long‐term, data required by wave energy developers as they deploy their machines offshore. Wave…

Mohamed et al.
Now-a-days, the energy extraction and conversion from the ocean waves has attracted large attention. A number of wave energy conversion systems have been proposed to convert the mechanical energy of the ocean wave into electrical energy. This paper presents a review of the status of wave energy conversion (WEC) technology and discusses the different types of devices used in present power…

In the present work the wave energy propagation patterns in the western side of the Iberian nearshore were evaluated. This assessment takes into account the results provided by a wave modelling system based on spectral phase averaged wave models, which considers subsequent computational domains with increasing resolution towards the coast. The system was previously validated against both in…

Makai Ocean Engineering
Makai Ocean Engineering, Inc.’s Ocean Thermal Energy Conversion (OTEC) Heat Exchanger (HX) Testing program at the Ocean Energy Research Center (OERC) is focused on developing an economically viable OTEC power plant. Heat exchangers are one of the most expensive components in an OTEC power plant; proper heat exchanger selection is crucial to the economic viability of OTEC. Heat exchanger…

Heat exchangers are one of the most expensive components in an Ocean Thermal Energy Conversion (OTEC) power plant. Proper heat exchanger selection is crucial to the economic viability of OTEC. Heat exchanger development must balance size, cost, and performance. To meet this goal, the OTEC Heat Exchanger (HX) Testing Program is divided into three areas: HX Performance Testing, HX Design…

This paper examines the challenges of efficiently harnessing wave energy. A variety of energy conversion device types is reviewed and a generic heaving buoy device selected for detailed examination. A number of modelling and control challenges are detailed and a hierarchical control structure is indicated. Both potable water production and electricity generation are included as possible uses…

Müller et al.
Marine energy conversion systems are highlighted among nonconventional renewable energy sources for their availability and energy density. Most marine energy conversion systems are based on multigenerator units or arrays, projected to inject power to the grid in the megawatt range. The current solution for regulating generators and managing power output is the use of two-level voltage-source…

The performance assessment of industrial marine energy converters involves the integrated treatment of their hydrodynamic design and the optimization of their device hulls. Nowadays, such tasks require extensive experimental work and simulation plans, consuming considerable resources and time. In this comprehensive review of integrated approaches to numerical and experimental testing, the…

This work aims at investigating the impact of different tidal turbine locations on hydrodynamics in near-field and far-field flow; thus, three- and two-dimensional (3- & 2-D) models were exploited in combination and applied in a case study of Putuo-Hulu Islands’ tidal farm. We present a method for the simplification of tidal turbine which, based on the energy equation, determines turbine’s…

Australia has considerable wave and tidal ocean energy resources. Development of the emerging ocean renewable energy (ORE) industry in Australia offers opportunities to build Australia's blue economy, while actively contributing to committed carbon mitigation measures. Many interdisciplinary challenges are currently hampering development of the industry in Australia, and globally, including…

Marine renewable energy has the potential to solve both the energy-security and coastal-protection problems affecting coastal societies. In this article, the potential benefits arising from the combination of marine renewable energy technologies with infrastructural needs for coastal protection and other local needs are analysed. Classifications of technologies are developed to inform future…

The efficiency in a horizontal axis tidal turbine (HATT), ??, is the determinant factor for tidal energy system. Accordingly, predicting the ?? of tidal turbines in the real sea environment is critical important to achieve the maximum performance of HATTs. However this performance is under great threat caused by marine fouling. And the understanding of the fouling effect is still barely known…

The nascent wave energy sector has the potential to contribute significantly to global renewables targets, yet at present there are no proven commercially viable technologies. Macro-economic assessment is seldom used to assess wave energy projects, yet can provide insightful information on the wider economic benefits and can be used in conjunction with techno-economic analysis to inform policy…
