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.

NEMMO report: Study on socio-economic impacts of tidal energy This report presents the results of the socio-economic assessment (SEA) carried out for the NEMMO project. The SEA is a well-established method that has helped in understanding the potential positive and negative socio-economic impacts of the NEMMO project innovations. For this study, the UNEP/SETAC…

Ocean energy has emerged as a highly promising and environmentally sustainable means of generating renewable electricity, owing to its vast untapped potential. This study focuses on an array of ocean energy technologies, which include tidal energy, wave energy, OTEC (Ocean Thermal Energy Conversion), salinity gradient energy, and ocean current energy. It examines various power generation…

In Canada’s Haida Gwaii archipelago, roughly 120 km off the northern coast of British Columbia, the north electrical grid uses more than 7 million liters of diesel to provide power to about 2500 people each year (the south grid uses roughly 3 million liters for roughly 2000 people). For long-term resident Laird Bateham, the predictability of the tides pointed to an obvious alternative. He…

The surf zones are significantly affected by tides, however, several gaps still in knowledge of fish assemblages in surf zones response to spring-neap and daily tidal cycles. We investigated fish assemblages in a surf zone of Gaolong Bay in China. The dynamics of fish assemblages were examined during the neap tide and the spring tide to test the hypotheses that (1) fish assemblages reflect a…

Morlais is a Menter Môn grid-connected, tidal stream array demonstration project located to the west of Anglesey, Wales. The goal of this project is to benefit local communities, the economy and help tackle climate change by using renewable energy to generate clean low carbon electricity.

As climate change becomes a more pressing reality in the 21st century, governments around the world are setting targets to meet electricity production demand from renewable energy sources such as tidal streams. However, tidal stream environments are also important habitats for marine wildlife, including seabirds. Risk of collision and habitat displacement are the major negative effects of…

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…

The UK’s position as a leading nation in the global effort to slow climate change has now become synonymous with our position as one of the leading nations in the research, innovation and development of the ocean energy sector. The value of this position has only been emphasised in light of Russia’s ongoing illegal invasion of Ukraine, with the UK looking to further develop renewable …

The report is an expansion of the UK chapter of the IEA-OES Annual Report 2021 and summarises the progress of wave, tidal stream and tidal range technology, markets and policy achieved by the UK in the last year. The Ocean Energy Systems (OES) under the International Energy Agency (IEA), is an organisation advancing development and deployment of ocean energies in more than 20 countries.…

This guidance has been produced by Natural Resources Wales (NRW) to provide advice to developers about the information needed to inform environmental assessments of tidal lagoon developments in Welsh waters. The document provides an overview of the key environmental implications of tidal lagoon development in Wales. The guidance is not exhaustive and does not replace the need for…

Semidiurnal tidal currents can exceed 5 ms−1 in Minas Passage, Bay of Fundy, where a tidal energy demonstration area has been designated to generate electricity using marine hydrokinetic turbines. The risk of harmful fish–turbine interaction cannot be dismissed for either migratory or local fish populations. Individuals belonging to several fish populations were acoustically tagged…

Hydraulic structures can be a promising place for tidal energy extraction due to the high flow velocities, easy access to the power grid and easy access for maintenance. However, quantification of the impacts of a tidal power plant in a hydraulic structure is not straight forward. In 2015 a pilot plant consisting of an array of five Tocardo tidal turbines was installed in the Eastern Scheldt…

Water power is a flourishing segment of the renewable energy industry, and resilient, reliable technologies like marine energy and hydropower are poised to play a significant role in our energy demands in the years to come. Continuing this trajectory of growth, however, requires new talent and innovation. As part of the effort to thoughtfully attract the best and most qualified workers, the…

An area has been designated for demonstrating the utility of marine hydrokinetic turbines in Minas Passage, Bay of Fundy. Marine renewable energy may be useful for the transition from carbon-based energy sources, but there is concern for the safety of fish that might encounter turbines. Acoustic receivers that detect signals from acoustically tagged fish that pass…

In autumn 2021, Natural Resources Wales (NRW) advisory, as the Statutory Nature Conservation Body, was tasked by Welsh Government to progress a programme of Mapping of Environmental Considerations to support the spatial approach to marine planning. The aim of the work is to compile and present environmental evidence to support Welsh Government and others who are interested in exploring…

Due to the marine environment's complexity, optimising offshore foundations' design is still a major focus of the scientific and industrial community, since foundations represent a large portion of the total investment. Scour is one of the main causes that lead to ultimate, and service limit states, impacting design optimization and costs. Scour at monopile foundations has been extensively…

The environmental effects of hydrokinetic turbines are still under investigation, reflecting the emerging status of this technology. This study investigates the interaction between hydrokinetic rotor wakes and fish swimming, revealing insights into fish biomechanics in complex flows and assessing the environmental implications of marine energy solutions. We conducted numerical simulations with…

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,…
