Lee et al.
The deployment and operation of a floating and/or submerged tidal technology in the United States coastal water require characterizing tidal stream resource potential and assessing environmental conditions and satisfying all environmental permitting requirements. The waters of Cook Inlet, Alaska have some of the strongest and most consistent tidal currents in the U.S. This project seeks to…

Surface-placed wave energy converters, floating tidal turbines, and floating offshore wind platforms all require anchoring to the seabed with multiple mooring lines and electrical cables passing through the water column, from near the sea surface to the sea floor. Concerns have been raised that large whales may collide with and/or become entangled in lines and cables from renewable energy…

As the need for clean low carbon renewable energy increases worldwide, wind energy is becoming established in many nations and is under consideration in many more. Technologies that make land-based and offshore wind feasible, and resource characterizations of available wind, have been developed to facilitate the advancement of the wind industry. However, there is a continuing need to also…

Yang et al.
This paper presents a numerical modeling study for simulating in-stream tidal energy extraction and assessing its effects on the hydrodynamics and transport processes in a tidal channel and bay system connecting to coastal ocean. A marine and hydrokinetic (MHK) module was implemented in a three-dimensional (3-D) coastal ocean model using the momentum sink approach. The MHK model was validated…

Carlson et al.
The deployment of tidal turbines in coastal waters raises questions about the potential risk to marine animals from strike by rotating blades. Of particular concern are marine mammals that are already facing threats from other human activities as well as climate change. Regulators in the US who are charged with permitting the installation of tidal turbines have sought additional information to…

Halvorsen et al.
Snohomish Public Utility District #1 plans to deploy two 6 meter OpenHydro tidal turbines in Admiralty Inlet in Puget Sound, under a FERC pilot permitting process. Regulators and stakeholders have raised questions about the potential effect of noise from the turbines on marine life. Noise in the aquatic environment is known to be a stressor to many types of aquatic life, including marine…

The marine environment has the capacity to provide large amounts of clean, renewable energy through its waves and tides. As marine renewable energy (MRE) devices are being tested, concerns regarding the potential effects of MRE devices on marine organisms, habitats, and ecosystem processes continue to slow permitting. To address these concerns, and further advance the industry, an…
- Conference Paper:
Copping et al.
Concerns about the potential effects of marine renewable energy (MRE) devices on marine animals, habitats, and the environment continue to slow siting and consenting of devices worldwide. Such concerns are often fueled by scientific uncertainty around these environmental interactions, which leads to heightened perceptions of risk. By increasing our understanding of these risks, the MRE…

Copping et al.
Concerns about the potential effects of tidal turbines and wave energy devices on the marine environment continue to slow siting and permitting/consenting of single devices and arrays worldwide. While research studies and early results from post-installation monitoring over the past decade have informed interactions between marine renewable energy (MRE) devices, marine animals, and habitats,…

Hemery et al.
Marine energy devices harness power from attributes of ocean water to form a sustainable energy source. Knowledge gaps remain about whether marine energy systems can affect the environment, adding another threat to animal populations and habitats already under pressure from climate change and anthropogenic activities. To date, potential environmental effects have been studied under the scope…

Wang et al.
To assess the effects of tidal energy extraction on water quality in a simplified estuarine system, which consists of a tidal bay connected to the coastal ocean through a narrow channel where energy is extracted using in-stream tidal turbines, a three-dimensional coastal ocean model with built-in tidal turbine and water quality modules was applied. The effects of tidal energy extraction on…

Yang et al.
This paper presents an application of a hydrodynamic model to simulate tidal energy extraction in a tidal dominated estuary in the Pacific Northwest coast. A series of numerical experiments were carried out to simulate tidal energy extraction with different turbine array configurations, including location, spacing and array size. Preliminary model results suggest that array optimization for…

Potential environmental effects from tidal and wave devices are of concern to regulators, advisors, and other stakeholders in many nations. Monitoring results from early deployments and the first commercial arrays, coupled with targeted research studies, are providing a growing base of knowledge of how components of tidal turbines and wave energy …

Zydlewski et al.
Renewable energy harvested from ocean waves, tides, and winds as part of a portfolio of reliable low-carbon energy sources to address climate change and energy security is under consideration by many nations. Engineering designs and characterization of the harvestable resource are moving forward, particularly in Europe, Asia, and North America. At the same time, stakeholders and regulators…

Copping et al.
Developing a sustainable marine energy industry requires that devices be efficient, robust, and not harmful to biological and physical resources within the marine environment. In every nation exploring marine energy development, laws and regulations protect the marine environment and its resources as society strives to create a sustainable renewable energy source from the sea. A team of…

Copping et al.
As the wave and tidal industry plans for initial commercial deployments, significant uncertainties remain about the risks to marine animals and habitats from wave and tidal devices; this uncertainty continues to slow and complicate siting and permitting (consenting) processes. Advancement of the industry can be simplified if the level of uncertainty is reduced, allowing regulators and the…

Rose et al.
Regulators involved in consenting/permitting marine renewable energy (MRE) have faced multiple challenges due to relatively new, unfamiliar technologies and uncertainty surrounding potential environmental impacts. This has resulted in slow progress for the MRE industry, including long consenting timeframes and extensive and expensive monitoring requirements, which increase financial risk for…

The PRIMRE team (Portal and Repository for Information on Marine Renewable Energy) from the US national laboratories will present background on the PRIMRE system with a focus on the value and feasibility of sharing data and information internationally. As research and development activities in marine renewable energy begin to become widespread…

Freeman et al.
This poster presentation covered the uncertainty about effects of marine renewable energy (MRE) and how this continues to slow consenting/permitting processes. Another argument presented was that sharing the considerable body of information on MRE environmental effects can facilitate decision-making and regulatory processes. Ocean Energy Systems (OES)-Environmental, an international initiative…
