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.

Thennakoon et al.
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…

Unlike other parts of the world, Mexico has low ocean current speeds (~1 m/s). The Cozumel Channel is an example of a site where such turbines could be installed since average current speeds of the Yucatán Current yearlong are situated in the range of 0.88-1.04 m/s. In order to take advantage of the existing conditions at Cozumel, the development of a hydrokinetic turbine became the focus of…

Initial tests involved short-term deployments of the device on its moorings followed by disconnection and towing back to harbor for inspection. The testing program was undertaken in incremental stages, culminating in a three-month period of continuous grid-connected operation at the end of 2012. In exporting power to the UK grid, the SR250 became the world’s first floating…

As new sources of anthropogenic noise, arrays of current- and wave-energy converters (CECs and WECs, respectively) will add to other man-made and natural sources in the marine environment. Regulatory constraints and environmental concerns over the sound pressure levels produced by these devices may be a hurdle to their deployment and operation. The Marine Mammal Protection Act in the USA, for…

Martinez et al.
Renewable ocean energy is an alternative that will help reduce carbon emissions into the atmosphere. However, there is uncertainty about potential environmental impacts of the technologies involved, because these are new and untested, and methods for the evaluation and monitoring of environmental impacts are scarce. We performed a systematic literature review (well-structured and organized,…

The collision risk evidence base consists of key research studies and reports that define what we understand about the risk of collision with tidal turbines for marine mammals, fish, and diving seabirds. Additional information on collision risk can be found in the 2020 State of the Science (Chapter 3…

Soukissian et al.
We have reached a critical juncture for addressing climate change and must find ways to urgently and dramatically reduce our carbon emissions. Extraction of energy from offshore renewable energy sources is seen as one of the key measures that will enable this reduction. The EU highlights offshore renewable energy as a key enabler for achieving its carbon neutrality ambitions by 2050, as…

Li and Zhu
As an abundant, clean, and predictable source of renewable energy, tidal current energy provides a cost-effective alternative to fossil fuels. Tidal current energy harvesting technologies are still at their early stages of development. Even some advanced demonstration projects with full-scale tidal current energy converters (TCECs) still face considerable technical barriers, and their…

Hernández-Fontes et al.
The Atlantic and Pacific coasts of Mexico offer a variety of marine energy sources for exploitation. Although the Mexican government has made important efforts to reduce its dependence on fossil fuels, national participation in clean energies is still limited in terms of electricity production. This paper presents a practical theoretical assessment of marine energy sources around Mexico, with…

Hydrokinetic Energy Projects” (hereafter labeled “hydrokinetics”) refers to a class of devices that generate electricity from waves, tides, and ocean or river currents. Interest in these technologies has grown in recent years; at the end of 2010, there were more than 160 projects on file at Federal Energy Regulatory Commission (FERC), the primary federal agency with jurisdiction over…

Hariss et al.
Morocco has an exceptional maritime potential especially on its two 500-km Mediterranean and 300-km Atlantic coastlines. The assessment of this potential for marine currents, wind and temperature is largely necessary for the various activities related to the coastline: fishing, exploitation of aggregates, tourism, transport services, desalination and marine renewable energies.…

Yang et al.
Ocean currents represent an alternative source of clean energy given their inherent reliability, persistence and sustainability. The general ocean circulation is characterized by large rotating ocean gyres resulting in rapid ocean currents along the western boundaries because of the Coriolis Effect. The Gulf Stream system is formed by the western boundary current of the North Atlantic Ocean…

Ocean currents, such as the Kuroshio Current, are expected to be effectively used as marine renewable energy in order to supply sustainable energy and reduce greenhouse gas emissions. IHI is aiming to realize power generation using an ocean current and is working toward development of a floating type ocean current turbine system. Japan’s Exclusive Economic Zone (EEZ) extending outside…

Mendoza et al.
Ocean energy technologies are still at an early stage of development; only a handful of concepts are being invented and tested worldwide. The environmental impact of these devices is not always taken into account, mainly because of the prevailing uncertainty regarding its assessment. It is vital that attention is paid to the mitigation of potential negative impacts on physical and biotic…

Multibeam sonar has emerged as a powerful tool for environmental monitoring of marine renewable energy (MRE) devices. Moving away from manned operations, self-contained multibeam sonar systems may be costly at purchase, but are costeffective for long-duration, autonomous deployments. However, there is no single multibeam sonar configuration that suits all environments and MRE devices currently…

Marine Current Energy Generation (MCEG) is a new technology that can produce emission-free electricity by using the velocity of sea currents. This paper explores possible environmental, social and environmental impacts of MCEG in Indonesia, a developing country that is currently facing a shortage of electricity. Multi-criteria Decision Analysis (MCDA) is used to conduct an integrated…

In recent years there has been renewed interest in the renewable power generation from ocean energy worldwide as well as in South Africa. South Africa's energy market is overwhelmingly fossil fuel based. Currently, the country has been experiencing shortages. This paper deals specifically with the assessment of the deep sea marine current energy contained in the Agulhas current located off…

The Minerals Management Service (MMS) is charged with environmentally responsible management of federal Outer Continental Shelf (OCS) resources (e.g., oil and gas, sand and gravel, other mineral resources). The OCS includes the submerged lands, subsoil, and seabed, lying between the seaward extent of the states' jurisdiction and the seaward extent of federal jurisdiction. The seaward extent of…
