So far, very few studies have focused on the quantification of the environmental impacts of a wave energy converter. The current study presents a Life Cycle Assessment (LCA) study of the MegaRoller wave energy converter, aiming to contribute to decision making regarding the least carbon and energy intensive design choices. The LCA encompasses all life cycle stages from "cradle-to-grave" for the wave energy converter, including the panel, foundation, PTO and mooring system, considering its deployment in Peniche, Portugal. Background data was mainly sourced from the manufacturer whereas foreground data was sourced from the Ecoinvent database (v.3.4) and ReCiPe and CED impact assessment methods were applied. The LCA application to the MegaRoller device resulted in a global warming potential (GWP) of 33.8 gCO2 eq/kWh and Cumulative Energy Demand (CED) of 432 kJ/kWh. This LCA is aligned with all previous studies on MRE technologies in concluding the main environmental impacts a...

Energy from the oceans has the potential to make major contributions towards renewable energy targets being adopted by European Governments over the next 10-15 years. To transform this from a possibility into a reality within the time frames requires numerous support frameworks to be implemented which assist research and demonstration programmes and stimulated the sharing of knowledge and resource information between all relevant parties. The EC funded Coordinated Action on Ocean Energy puts into place funding and a platform to enables device developers, wave and tidal energy researchers and standards agencies to share knowledge and information which will facilitate the transition of wave and tidal energy from an energy research technology to one approaching commercial competitiveness within the medium-term time frame, 2010-2015.

Growing energy demand has increased interest in marine renewable energy resources (i.e., wave energy, which is harvested through wave energy converter (WEC) arrays. However, the wave energy industry is currently at a significant juncture in its development, facing a number of challenges which require that research re-focuses on a holistic techno-economic perspective, where the economics considers the full life cycle costs of the technology. It also requires development of WECs suitable for niche markets, because in Europe there are inequalities regarding wave energy resources, wave energy companies, national programs and investments. As a result, in Europe there are leading and non-leading countries in wave energy technology. The sector also needs to increase confidence of potential investors by reducing (non-)technological risks. This can be achieved through an interdisciplinary approach by involving engineers, economists, environmental scientists, lawyers, regulators and policy ex...

Ocean waves are a huge, untapped source with a higher energy density than solar and wind energy. Over the years, numerous designs for ocean wave energy converter systems (OWECS) have been proposed. This paper provides a comprehensive review and assessment of currently available OWECS using technology readiness levels (TRLs) scale developed by the US Department of Energy. TRLs are used by numerous industries to assess technical maturity and functional readiness of new technologies. The study finds that there are 20 OWECS which are at various stages of technological development. Out of these, 14, five and two OWECS are intended for deployment at near-shore, offshore and onshore locations, respectively. The study shows that OWECS technology is diverse and relatively immature compared to solar and wind energy technology. Finally, the study reveals a lack of convergence towards a single OWECS that is capable of energy extraction from onshore , near-shore and offshore locations.

Wave Dragon is a floating wave energy converter working by extracting energy principally by means of overtopping of waves into a reservoir. A 1:4.5 scale prototype has been sea tested for 20 months. This paper presents results from testing, experiences gained and developments made during this extended period. The prototype is highly instrumented. The overtopping characteristic and the power produced are presented here. This has enabled comparison between the prototype and earlier results from both laboratory model and computer simulation. This gives the optimal operating point and the expected power of the device. The project development team has gained much soft experience from working in the harsh offshore environment. In particular the effect of marine growth in the draft tubes of the turbines has been investigated. The control of the device has been a focus for development as is operates automatically for most of the time. This has led to improvements in the power take off, trim control and stability of the device.

In this paper, technical and economical studies conducted on the SEAREV Wave Energy Converter (WEC) are presented. This technology was first proposed in 2002 with the aim of addressing critical challenges in wave energy conversion. It consists of a closed floating hull in which a heavy pendulum oscillates. The controlled relative motion of the pendulum is used to produce electricity.

The present paper gives an overview of the lessons learnt from the project called Components for Ocean Renewable Energy Systems (CORES). In the context of this European funded 7 th Framework Programme research project, new components and systems for ocean energy devices were developed and trialed. The present paper also details the work packages, major achievements, significant impacts, summary results and the outcomes of the sea trials.
Although the first attempts to exploit wave energy go back to similar periods of other renewable energy sources, no particular technology has yet proved to be successful. Survivability in the ocean harsh environment will be one of the key features for commercial success of Offshore Wave Energy Converters.

Wave energy has a significant part to play in providing a carbon-free solution to the world's increasing appetite for energy. In many countries, there is sufficient wave energy to cater for the entire national demand, and wave energy also has some attractive features in being relatively uncorrelated with wind, solar and tidal energy, easing the renewable energy dispatch problem. However, wave energy has not yet reached commercial viability, despite the first device designs being proposed in 1898. Control technology can play a major part in the drive for economic viability of wave energy and this paper charts the progress made since the first wave energy control systems were suggested in the 1970s, and examines current outstanding challenges for the control community.

Solutions to today energy challenges need to be explored through alternative, renewable and clean energy sources to enable a diverse energy resource plan. An extremely abundant and promising source of energy exists in oceans. Ocean energy exists in many forms. Among these forms, significant opportunities and benefits have been identified in the area of ocean wave energy extraction, i.e., harnessing the wave motions and converting them into electrical energy.
