Woodruff et al.
Energy generated by the world’s oceans and rivers offers the potential to make substantial contributions to the domestic and global renewable energy supply. However, the marine and hydrokinetic (MHK) energy industry faces challenges related to siting, permitting, construction, and operation of pilot and commercial-scale facilities. One of the challenges is to understand the potential effects…

Whiting et al.
Development of the marine renewable energy (MRE) industry has been challenged by uncertainty about potential environmental effects, which has resulted in slowing of permitting/consenting processes, and ultimately to constraints on the industry. These challenges result from a lack of sufficient devices in the water from which to learn, a dearth of quality monitoring data, and a lack of…

Copping et al.
The marine renewable energy (MRE) industry is in the early stages of commercial development. In addition to the challenges of deploying and maintaining devices under harsh ocean conditions and transporting electricity to shore, concerns around potential environmental effects continue to slow permitting (consenting) processes. Regulators and stakeholders perceive a wide array of potential…

Copping et al.
The U.S. Department of Energy (US DOE) has mobilized its National Laboratories to address the broad range of environmental effects of ocean and river energy development. The National Laboratories are using a risk-based approach to set priorities among environmental effects, and to direct research activities. Case studies will be constructed to determine the most significant…

Copping et al.
Commercial marine renewable energy (MRE) developments can take extended periods of time to progress, in part due to complicated permitting processes that require expensive data collection and data review. Much of this delay is associated with uncertainty around potential effects of MRE on marine animals and habitats, leading regulators and stakeholders to believe that significant risks may…

Freeman et al.
Currently, the marine renewable energy (MRE) industry is struggling with high costs of baseline environmental assessments and post-installation monitoring, as well as long timelines for obtaining permits, leading to uncertainty and risk for financing projects. One solution to overcome such barriers and help advance the MRE industry could be the ability to transfer learning, analyses, and…
- Conference Paper:
Hemery et al.
The installation, presence, operation, and decommissioning of marine renewable energy (MRE) devices inevitably alters the surrounding ocean habitats. These changes may include direct effects on the benthos from the installation or removal of foundations and anchors, changes in community composition on and near devices, artificial reef effects, and indirect …

Severy et al.
Grays Harbor Wind LLC (GHW) is proposing to develop a floating offshore wind farm offshore of west Grays Harbor County, Washington (Grays Harbor). The proposed GHW Offshore Wind Project (Project) would entail construction, installation and operation of a 1,000-megawatt (MW) offshore wind farm consisting of approximately 75 floating units, each containing a floating foundation and wind turbine…

Copping et al.
The pace of development for wave and tidal energy projects worldwide continues to be hindered by uncertainty surrounding potential environmental effects of the devices and the balance of system. To respond to this uncertainty the Ocean Energy Systems (OES) international agreement developed a collaborative initiative (Annex IV). Over an initial three-year period (2010-2012) Annex IV collected…

Polagye et al.
Tidal hydrokinetic energy has the potential to provide clean, reliable power, and emerging turbine designs are making production of electricity from ocean energy technologically and economically feasible. Tidal energy projects could be a viable renewable energy source, displacing fossil fuel-based energy resources, providing benefits to the marine environment through the mitigation of carbon…

The pace of development for marine energy projects worldwide continues to be hindered by uncertainty surrounding potential environmental effects of wave and tidal devices and the balance of system. In response to this continued uncertainty, member nations of the Ocean Energy Systems (OES) developed a collaborative project – Annex IV – to increase collection and sharing of knowledge, research…

Copping et al.
The potential risk to marine mammals colliding with turbines is one of the primary environmental concerns slowing tidal energy development in the US and Europe. Few field observations of interactions between marine animals and tidal turbines have been reported [1], necessitating supplemental risk analyses and modeling to help fill the gap. This study provides a surrogate measure of the…

Freeman et al.
Marine renewable energy (MRE) can benefit from broad outreach and engagement with a wide variety of audiences to raise awareness, address concerns about potential environmental impacts, generate public support, build a future workforce, share progress on research and development, and succeed within the larger blue economy. OES-Environmental is an international initiative of 16 countries that…

Freeman et al.
The marine renewable energy (MRE) industry has seen an increase in deployments over the past 10 years, particularly in Europe. However, other areas of the globe are still in the beginning stages of MRE development including the Americas. A small number of devices have been deployed in Canada and the United States, while South and Central America have seen very few if any devices in the water […

Hemery et al.
MARINE renewable energy (MRE) developments, such as those harvesting wave or tidal energy, will need to grow towards large-scale arrays for the sector to successfully contribute toward the portfolio of sustainable energy alternatives and fight global climate change. However, this growth must be accompanied by the investigation of potential environmental effects at larger scales, and will…

Copping et al.
Commercial development of tidal stream energy is hampered by technical and financial challenges, and impeded by uncertainty about potential environmental effects that drive environmental risk assessments and permitting (consenting) processes. The effect of greatest concern for operational tidal stream energy devices is the potential for marine animals to collide with turbine blades, resulting…

Many marine mammal populations worldwide are in decline due to stresses from climate change and interactions with anthropogenic activities such as fishing, coastal construction petroleum extraction, and commercial shipping. The advent of the marine renewable energy industry has raised questions, particularly for tidal turbines. However, it is technically very difficult to observe close…

Long et al.
The rapid growth of renewable offshore energy development has raised concerns that underwater noise from construction and operation of offshore devices may interfere with communication of marine animals. An underwater sound model was developed to simulate sound propagation from marine and hydrokinetic energy (MHK) devices or offshore wind (OSW) energy platforms. Finite difference methods were…
