Stefek et al.
Reducing power fluctuations is essential for controlling the integration impacts of wave energy converter (WEC) plants in both distribution and transmission grids, and in stand-alone isolated power systems. This paper presents an analysis on the cost of and how a battery storage system can be used to further reduce the variation of power generated from the WEC due to the fluctuating nature of…

The objective of this paper is to calculate the Levelized Cost of Energy (LCOE) and the Internal Rate of Return (IRR) of a floating wave energy farm using Geographic Information Systems (GIS). The methodology has been applied to the Galician coast, located in the North-West of Spain, where the waves potential is really high. In addition, a particular wave energy converter has been considered:…

Wave energy has potential of contributing significantly to the world’s electricity production, but the cost of electricity is still too high to be competitive with other energy technologies. In this paper, an economical model for large-scale wave energy systems is developed and used to optimize parks of point-absorbing wave energy converters. The optimization is performed with a genetic…

Marmara Sea, located between Black Sea and Aegean Sea, is an important sea for ocean engineering activities. In this study, wave power potential of Marmara Sea was investigated using the third generation spectral wind-wave model MIKE 21 SW with unstructured mesh. Wind data was obtained from ECMWF ERA-Interim re-analyses wind dataset at 10 m with a spatial resolution of 0.1° for the period of…

Based on ERA-Interim reanalysis wave field data for the 36 years from 1979 to 2014, the temporal and spatial distributions and development potential of wave energy are studied in detail in the offshore and relatively nearshore waters adjacent to the Zhoushan Islands. The results show that areas of relatively high wave energy are located in the offshore waters to the east and southeast of the…

Wave power is an abundant source of energy that can be utilized to produce electricity. Therefore, assessments of wave power resources are being carried out worldwide. An overview of the recent assessments is presented in this paper, revealing the global distribution of these resources. Additionally, a study, which aims to assess the spatial distribution of the Baltic Sea near-shore wave power…

Wave characteristic assessments of wave energy test sites provide a greater understanding of prevailing wave conditions and are therefore extremely important to both wave energy test site operators and clients as they can inform wave energy converter design, optimisation, deployment, operation and maintenance. This research presents an assessment of the wave resource at the Atlantic Marine…

Ocean wave energy is one of the cleanest renewable energy sources around the globe, but wave energy varies widely from place to place and from time to time. The long-term variability of wave power at 20 locations in the Indian shelf seas from 1979 to 2018 is described here using the European Centre for Medium-Range Weather Forecasts recently released ERA5 reanalysis hourly data. The…

Understanding the hydrodynamic performance of floating energy converters is a complex challenge. Hence, physical modelling is necessary to evaluate the performance of innovative designs and validate them. The present paper shows the experimental work performed to validate a new floating semisubmersiblestructure which combines wave energy converters (3 Oscillating Water Columns, OWC) and wind…

Accurate model hindcast of wave climate in complex estuarine systems is challenging because high-resolution wave models and wind forcing are required. In this study, a modeling approach using the unstructured-grid Simulating WAves Nearshore and a wind product from a high-resolution regional Weather Research and Forecasting hindcast was used to simulate the swell and wind-sea climate in the…

Wang et al.
Deployment of wave energy converters (WECs) relies on consistent and accurate wave resource characterization, which is typically achieved through numerical modeling using deterministic wave models. The accurate predictions of large-wave events are critical to the success of wave resource characterization because of the risk on WEC installation, maintenance, and damage caused by extreme sea…

Marine Energy Wales
The global resource potential for marine renewable energy is vast, and as yet, largely untapped. Theoretical estimates indicate that harnessing the incredible power of the sea could provide a clean, low carbon, sustainable electricity source to meet the demands of the entire planet.
With some of the best marine resources in the world, Wales is playing a vital role in this emerging…

Xu et al.
A careful and detailed wave resource assessment is essential for identification of a successful wave energy project. However, current approaches inherently limit application to specific locations and wave energy converter architectures, rather than providing for broad application across the industry. Generally, a site is identified based on either the gross resources, or an assessment of…

Power take-off is an indispensable link in wave energy utilization, and its efficiency should be comprehensively investigated at both full load and part load for the effective conversion in variable wave conditions. However, up to now, the research about this issue is still scarce because of its complexity and difficulty. To overcome this obstacle, this paper studies the overall conversion…

This paper presents a summary of recent progress towards the development and upscaling of an emerging class of electrostatic power take-off (PTO) systems for wave energy converters (WECs), called dielectric elastomer generators (DEGs). DEGs are electromechanical devices able to convert mechanical energy into electrical energy by exploiting the deformation of rubber-like dielectric materials.…

Tidal energy systems and specifically tidal barrages are renewable energy systems, that use the potential energy of tides to produce electricity. Actually, there are few tidal power stations operating, although recent studies show the potentiality of installing new units in a recent future due to the constant improvement of the technology related. As in other conventional hydropower systems,…

The global development of the offshore renewable energy sector has been driven by extensive investment and research in the utilization of offshore renewable energies, mainly at the regional level. However, for mid to long-term marine energy development planning, a comprehensive assessment of the global potential for the exploitation of the main offshore resources is required. This work…

One of the biggest uncertainties in tidal stream energy resource assessment is how tidal energy conversion, particularly at large scale, will interact with the resource. As few arrays are currently operational, data collected from these developments tends to be commercially sensitive. Therefore, array interaction with the resource is generally assessed using numerical models. A fully three-…

The wave and tidal sector is moving from single device demonstration sites to multi-device arrays. One of the challenges the industry faces is the design of a cost effective and efficient electrical network to collect and transmit power from these devices to the shore. For some projects, such as MeyGen in the Pentland Firth, the solution is to connect each turbine to the shore individually.…

The marine energy industry has reached the stage where a number of devices have completed pre-commercial, full-scale demonstration. Over the next few years, array-level projects will start to be constructed. One of the challenges facing the marine energy industry is the need to reduce the Levelised Cost of Energy (LCOE) of these projects. The lack of a standard marine electrical architecture…
