Ocean Energy Technology: Gaps and Barriers

  • Country: United Kingdom
  • Published Date: 01/11/2013

Technology gaps can be considered as areas in which new enabling technologies or innovation is required in order to make technical progress in the ocean energy sector. Barriers to deployment are challenges that inhibit the deployment of ocean energy technology, making it difficult for the sector to achieve its targets and goals.
This document presents technology gaps and barriers in developing the ocean energy sector – the solutions to which could represent a key opportunity to reinforce Europe’s leadership in RD&D as the ocean energy sector progresses from concept to commercialisation.

Technology Innovation Needs Assessment (TINA) Marine Energy Summary Report

  • Country: United Kingdom
  • Published Date: 01/08/2012

The TINAs aim to identify and value the key innovation needs of specific low carbon technology families to inform the prioritisation of public sector investment in low carbon innovation. Beyond innovation there are other barriers and opportunities in planning, the supply chain, related infrastructure and finance. These are not explicitly considered in the TINA’s conclusion since they are the focus of other Government initiatives, in particular those from the Office of Renewable Energy Deployment in DECC and from BIS. This document summarises the Marine Energy TINA analysis and draws on a much more detailed TINA analysis pack which will be published separately.

The Role of the Federal Energy Regulatory Commission in Authorizing Hydrokinetic Technology Projects

  • Country: NA
  • Published Date: 01/01/2010

There is growing interest in hydrokinetic technologies used to harness the free-flowing, renewable energy of the ocean’s waves, currents, and tides, as well as inland rivers, without the use of dams. In response to this growing interest, the Federal Energy Regulatory Commission has experienced a surge in activity regarding the testing and development of hydrokinetic projects. Although the Commission’s well-tested regulatory process is compatible with these hydrokinetic projects, providing a strong foundation for overseeing their orderly development, the Commission has been taking steps to adapt its program to the challenges of a new technology. Using input actively solicited from the industry, state and federal agencies, Native American tribes, and the public, the Commission has adapted its administrative procedures to meet the challenges of regulating this nascent industry.

Tidal Technology Development and Deployment in the UK: Tidal Technologies: Key issues across planning and development for environmental regulators

  • Country: NA
  • Published Date: 01/06/2011

Renewable energy technologies are commonly seen as a panacea for the environmental problems associated with power generation, not just in terms of greenhouse gas emissions but also by virtue of other impacts such as pollution and habitat destruction (e.g. Dincer 1999). This may well be true of wave and tidal energy developments, but the fact is that there are few direct observations from which to judge the nature and scale of impacts. This is partly because of the emergent state of the industry, but also because research into this field has tended to focus on the nature of the resource and on the engineering aspects of exploiting it rather than on the environmental consequences of such exploitation.This is not to say that there is no evidence base from which to draw inferences on the potential for wave and tidal energy developments to impact upon the marine environment. Information from impact studies of other human activities provide valuable insights into how some aspects of power generation may interact with the environment. Coupled with knowledge about the vulnerabilities of particular species and habitats and about the interrelatedness of physical and ecological processes, this information provides at least a starting point for understanding the likely consequences of marine energy extraction for the physical and biological milieus in which it is placed. A number of recent reviews (e.g. Gill 2005, Inger et al. 2009, ICES 2010a, 2010b, Shields et al. 2011) have drawn together much relevant information for a qualitative appreciation of the perceived potential for environmental interactions involving marine renewable energy developments. Several types of interaction may be distinguished:
-energy extraction impinging upon natural processes
-operational effects on marine biota, acting through device operation, maintenance and decommissioning
-provision of new ecological space through the physical presence of devices and other development structures
-displacement of other human activities, modifying the locus and nature of their impacts
The least attention has so far been paid to the first of these aspects, particularly in terms of intervention in physical processes. For this reason, this document places particular emphasis on the previously under-reviewed topic of potential impacts on physical processes, the more so because many other potential impacts stem from the physical impacts as first causes. We pull together the first comprehensive review of the potential for wave and tidal energy extraction to impinge upon physical processes in the near- and far-fields of developments, before going on briefly to examine the implications for ecological processes. Operational effects are considered mainly in terms of noise and collision risk; pollution risk involving release of oil and chemicals is probably fairly low, and is a general risk for human activities at sea rather than being particular to wave and tidal energy extraction. Changes to ecological space are considered in terms of reef effects and structures functioning as fish aggregation devices. Finally, we focus on marine fishing as the principal interaction with other sea users that is likely to have environmental implications.

Environmental Assessment for Proposed Wave Energy Technology Project in Kaneohe Bay Hawaii

  • Country: United States of America
  • Published Date: 23/01/2003

The Office of Naval Research proposes the phased installation and operational testing of Wave Energy Conversion (WEC) buoys off North Beach, Marine Corps Base Hawaii, Kaneohe Bay (MCBH Kaneohe Bay). This action is being proposed to test wave energy as a renewable, non-polluting power source. Department of Defence (DoD) installations are vulnerable during times of national conflict due to their reliance on conventional fuels for electrical power generation. Coastal DoD sites with suitable wave energy potential could obtain supplemental power using wave energy if it can be demonstrated to be efficient, reliable, and cost-effective. Testing is needed to obtain operational data to validate the WEC technology developed by Ocean Power Technologies, Inc. The Congressional appropriation to conduct this test stipulates that testing is to occur in Hawai’i, which has coastal locations with high wave energy potential. The objectives of the Proposed Action are the following: Objective 1. Conduct the test in a high wave energy density environment, characterized by an average annual wave height of 3 feet (ft) or 1.0 meter (m) (minimum) to 5 ft or 1.5 m (optimum), which is a likely characteristic of the environment for future operational use of the WEC technology at other locations. Objective 2. Challenge the system under variable conditions, such as winter storms, to investigate the survivability of the system. Objective 3. Collect statistically significant data sets to validate assumptions and findings. Increasing the period of collection, e.g., up to five years, would increase the likelihood of obtaining statistically significant data sets for various test parameters, such as seasonal changes and their effects on the system. Objective 4. Observe the effect on system performance when more than one buoy is present. Objective 5. Use a test site for the system that minimizes the costs of installation, operations, and maintenance. Objective 6. Minimize the risk of system failure, to optimize the collection of data, by maximizing the survivability of the system.
