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 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…

This book provides inspiring case studies of today’s most promising marine energy devices and developments, including full-scale grid-connected prototypes tested in sea conditions. It also covers the European Marine Energy Centre (EMEC) in Orkney, Scotland, where many of the devices are assessed.
Topics discussed:
- global resources – drawing energy from the World’s waves and…

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…

Northwest Energy Innovations
Northwest Energy Innovations (NWEI), Naval Facilities Engineering Command’s Expeditionary Warfare Center (NAVFAC/EXWC), University of Hawaii’s Hawaii National Marine Renewable Energy Center (HNMREC) and the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) are working collaboratively to deploy and test NWEI’s half-scale multi-mode wave energy converter (NWEI Device).…

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…

Zabala et al.
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…

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…

Draycott et al.
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…

Marrone et al.
The present work addresses the evaluation by numerical simulation of the extreme loads acting on a flap-type wave energy converter. To this aim, a realistic situation is considered: an extreme wave impacting a bottom-mounted pitching device, consisting of a partly submerged flap, placed in front of a dike on the coast of Bayonne, south-west Atlantic coast, France. The SPH model can be an…

This report provides insights of 20 ocean energy projects and 5 policy initiatives on the OES member countries. These projects are good examples of the intense activity of this emerging sector but there is a much larger number of relevant projects being developed world wide not included in this report.

Marine renewable energy has the potential to produce up to 20% of the UK’s current electricity demand, leading to extensive research and development activities in this area. As the industry of wave energy progresses toward commercialisation, a number of barriers still limit its potential, including the cost of energy. A significant portion of this is the cost of operation and maintenance…
