This site-wide search returns results for all documents, events, metadata, and stories in Tethys, prioritizing the best matches. Partial word matches are returned (e.g. "environment" finds "environmental"), but every entered term must be found. If you don't find any results, try reducing the number of words entered or removing special characters. Filters to the right can help narrow your search. Tethys now features an integrated search with other marine renewable energy databases in PRIMRE - click the buttons below "Showing Results for" to search other integrated databases.

Spicer et al.
Tidal energy extraction is increasingly being studied as a potential renewable energy resource in estuaries worldwide. Although it is understood that energy extraction via tidal stream turbines can modify currents and transport within estuaries, it is not clear how the underlying nonlinear physical mechanisms dictating tidal hydrodynamics are modulated. This research investigates the influence…

Bordbar et al.
Waterbodies’ thermal energy potential, as a green, renewable, and limitless source of energy, can be exploited in response to the growing energy demands of islands and coastal cities. Up to now, the technologies that have been developed for this purpose include seawater air-conditioning, surface water heat pump, and ocean energy thermal conversion systems or their combinations, which are…

This deliverable provides a critical analysis of management measures that can be used to mitigate or manage the potential environmental effects of wave and tidal energy developments. The aim of this deliverable is to critically analyse the environmental mitigation and monitoring measures that have been used to date in completed or planned wave and tidal energy projects. This will provide…

Tidal-stream Energy Converter (TEC) arrays are expected to reduce tidal current speeds locally, thus impacting sedimentary processes, even when devices are positioned above bedrock. Tidal dissipation can produce high suspended sediment concentrations (turbidity maxima) which are important for biological productivity. Also, devices will potentially impact morphological features further afield,…

Yang et al.
A hybrid numerical capability is developed for the simulation of offshore wind farms, in which large-eddy simulation is performed for the wind turbulence, and a potential flow based method is used for the simulation of the ocean wave field. The wind and wave simulations are dynamically coupled. The effect of wind turbines on the wind field is represented by an actuator disk model. This study…

van der Molen et al.
A model study was carried out of the potential large-scale (> 100 km) effects of marine renewable tidal energy generation in the Pentland Firth, using the 3-D hydrodynamics–biogeochemistry model GETM-ERSEM-BFM. A realistic 800 MW scenario and a high-impact scenario with massive expansion of tidal energy extraction to 8 GW scenario were considered. The realistic 800 MW scenario suggested…

The primary goal of the Department of Energy’s Water Power Program is to efficiently develop and utilize the country’s marine hydrokinetic (MHK) and conventional hydropower (CH) resources. The program has recently identified the need to better understand the potential for hydrokinetic energy development within existing canal systems that may already have integrated CH plants. Hydrokinetic (HK…

In this paper, the application of a 3D numerical model covering the area of Pentland Firth channel (Scotland, UK) to investigate the hydrodynamics related to tidal energy extraction is presented in detail. A full validation analysis is carried out so that the fully operational 3D hydrodynamic model could be applied with confidence in order to explore possible impacts of tidal devices on the…

In this paper the application of a 3D numerical model covering the area of the Pentland Firth channel (Scotland, UK) to investigate the hydrodynamic and morphodynamic environment related to tidal energy extraction is presented in detail. The open source Delft3D flow model is used. Hydrodynamics of a regional Pentland Firth model provided the boundary conditions for a high resolution local…

Rtimi et al.
The Rance estuary is a relatively small low-inflow steep-sided ria, located in the Brittany coast of northern France, with a maximum spring tidal range of 13.5 m at the mouth. Taking advantage of this hypertidal regime, the first and largest operational tidal power station in the world was built at the estuary mouth and is in operation since the 1960s. Despite a well-known effect of the…

European Scalable Offshore Renewable Energy Source (EU-SCORES) is a highly ambitious EU-funded project aimed at demonstrating and unlocking the large-scale potential of multi-source, offshore renewable energy farms across different European sea basins. This will be achieved through two highly comprehensive and impactful demonstrations: (1) An offshore solar PV system in Belgium co-located with…

The aim of the present work is to describe a computational platform (CSIAM-Computational System for Impact Assessment of the Marine energy farms) that can easily be implemented to identify the expected coastal impact of a particular marine energy farm. Several case studies are discussed in order to present the versatility of this tool, including coastal areas from Portugal (central part),…

This document considers the impact of the activities associated with the decommissioning of the Beatrice Field in the Central North Sea. The development comprises the bridge-linked Beatrice Alpha Drilling (AD) and Beatrice Alpha Production (AP) platforms which are centrally located in the field, with the Beatrice Bravo (B) and Beatrice Charlie (C) platforms located 5.6 km to the northeast and…

Wind power in China is experiencing accelerating growth to meet the need for structural reform of the energy supply, however its impact on the ecological environment urgently needs to be taken into account. In this study, the impact of a wind farm in Gonghe County, Qinghai Province, China, on local land surface temperature (LST) was explored by removing the temporal background using year-by-…

The impacts of wave farms (arrays of wave energy converters, or WECs) on the nearshore must be fully understood for wave technology to develop and thus contribute to a sustainable, carbon-free energy mix in the near future. The objective of this work is to investigate the role played by the farm layout on the wave propagation patterns leewards and the implications for longshore sediment…

O'Dea et al.
An alternative metric for assessing nearshore hydrodynamic impact due to Wave Energy Converter (WEC) arrays is presented that is based on the modeled changes in alongshore radiation stress gradients in the lee of the array. The metric is developed using a previously observed relationship between measured radiation stresses and alongshore current magnitudes. Next, a parametric study is…

For wave energy to become a fully-fledged renewable and thus contribute to the much-needed decarbonisation of the energy mix, the effects of wave farms (arrays of wave energy converters) on coastal systems must be addressed. The objective of this work is to investigate the effects of wave farms on the longshore sediment transport and shoreline evolution of a gravel-dominated beach and, in…
