Introduction of Tidal Energy
Tidal Energy Systems, 2019Co-Authors: Vikas Khare, Cheshta Khare, Savita Nema, Prashant BaredarAbstract:Abstract The capability of creating power from Tidal streams is colossal. Tidal Energy is an inexhaustible source that has an extra incentive in a future Energy showcase as to other sustainable power sources because of its high consistency. Tidal Energy innovations are described by CO 2 emanation free power, along these lines empowering Energy security and adding to monetary development and employment creation in beach front and remote ranges. Generous advances are at present being made by the European Union as respects the decrease of ozone-harming substance emanations, a sustainable power source, and Energy efficiency, with a specific end goal of an introduced limit of 3.6 GW of sea Energy by 2020, and to accomplish a future introduced limit of 188 GW of sea Energy in 2050. This chapter includes historical and parallel scenarios of Tidal Energy systems, which include global and Indian scenarios of Tidal Energy systems. Further basic principles, different technology, components, and recent advancements of Tidal Energy systems are discussed in this chapter. Finally, the study also identifies the advantages and limitations of Tidal Energy projects.

Prefeasibility Assessment of a Tidal Energy System
Tidal Energy Systems, 2019Co-Authors: Vikas Khare, Cheshta Khare, Savita Nema, Prashant BaredarAbstract:Abstract Prior to installation and operation, the prefeasibility study of a Tidal Energy system is customarily carried out. The prefeasibility analysis includes the study of climatic conditions, longitude, latitude, a study of the coastal area, low and high tide and Tidal current of the proposed site, and availability of Tidal Energy sources and assessment of its potential load and load demand of the application site. The prefeasibility study assists in finding the best location to develop a Tidal Energy system for a particular demand. This chapter includes a resource-assessment model in terms of one-dimensional, two-dimensional, and three-dimensional resource assessments. Resource assessments are also categorized in terms of theoretical, technical, practical, accessible, and viable Tidal current Energy resources. Further resource assessment is done by regression-based mathematical analysis and analyzed with software that is related to the Tidal Energy resource assessment. The project duration is analyzed with the help of two project management techniques, the critical path method (CPM) and the program evaluation and review technique (PERT). In the next part of this chapter, static and field surveys are done in terms of quantitative observation and also the challenges of measuring water current in coastal areas. Location assessment is also analyzed by the farm as well as flux methods by dynamic programming and by transmission line analogy. Finally, this chapter explains detailed project report preparation and appraisal related to Tidal power plant installation.

Fish, finances, and feasibility: Concerns about Tidal Energy development in the United States
Energy Research & Social Science, 2019Co-Authors: Stacia J. Dreyer, Ezra Beaver, Hilary Jacqueline Polis, Lekelia D. JenkinsAbstract:Abstract This article explores stakeholder views on Tidal Energy in the state of Washington. Through compiling and analyzing three qualitative datasets, we take a triangulated approach to better understand stakeholders’ positive and negative views, concerns, and needs regarding Tidal Energy and if and how these are represented through print and online news sources. We analyzed comments submitted during the permitting process for the Admiralty Inlet Pilot Tidal Project, comments included as part of a Tidal Energy mail survey sent to Washington residents, and media articles about Tidal Energy. We found four types of concern themes within negative views towards Tidal Energy: environmental, social, economic, and technical. Shared concerns between organized stakeholder groups and resident stakeholders about the project and Tidal Energy in general included concerns related to the harm to marine life, the loss of native fishing rights, expensiveness of development, increased electricity costs, and the engineering challenge of developing Tidal Energy. Concerns unique to stakeholder groups for the project included threats from scaling up, issues related to public safety and security, damage to cables, inability to stop the turbine, harm to terrestrial flora, and sediment disruption and contamination. Positive views were commonly associated with the need to address environmental issues, technological innovation and leadership, desire to have a diverse Energy portfolio, and economic benefits.

Changing Tides: Acceptability, support, and perceptions of Tidal Energy in the United States
Energy Research & Social Science, 2017Co-Authors: Stacia J. Dreyer, Hilary Jacqueline Polis, Lekelia D. JenkinsAbstract:Abstract Tidal Energy is a renewable Energy source that could be used to help mitigate climate change. Tidal Energy technology is in the early stages of development and views towards this technology and Energy source are not well understood. Through a representative mail survey of Washington State residents, we assessed attitudes and behaviors related to Tidal Energy, perceived benefits and risks, and climate change beliefs. Higher levels of perceived benefits and climate change beliefs were associated with increased acceptability of and support for Tidal Energy whereas greater perceived risks were associated with decreased acceptability and support (acceptability being an attitudinal construct, support a behavioral construct). Coastal residents reported higher levels of acceptability and support than non-coastal residents. Pulling from innovation theory, we show that levels of support depended upon the development lifecycle stage of the technology. Support declined once the project moved into the water from the lab, however, grid-connected pilot projects were more likely to be supported than those without grid-connection. Policies developed to encourage the development of Tidal Energy may be more accepted and supported if they include incentives for pilot phases with grid-connection.

Public Willingness to Pay and Policy Preferences for Tidal Energy Research and Development: A Study of Households in Washington State
Ecological Economics, 2017Co-Authors: Hilary Jacqueline Polis, Stacia J. Dreyer, Lekelia D. JenkinsAbstract:Puget Sound in Washington State (WA) has significant Tidal Energy resources, but the industry is at a nascent stage of development. At this stage, the availability of research and development (R&D) funding plays a critical role in the success or failure of renewable Energy schemes. However, information about public interest in developing marine renewable Energy technology, including Tidal Energy technology, in WA and the U.S. has been limited. Responses to a dichotomous choice referendum question on a mail survey sent to a representative sample of WA households were used to estimate residents' Willingness to Pay (WTP) for Tidal Energy R&D. Public preferences for policies to support Tidal Energy R&D were also assessed. WA households are WTP between $29M and $127M annually for Tidal Energy R&D, indicating public preference for an increase in government spending on Tidal Energy R&D over current levels. Public perceptions of potential social, environmental, and economic risks and benefits of developing Tidal Energy emerged as highly significant predictors of WTP.

Numerical modelling of hydrodynamics and Tidal Energy extraction in the Alderney Race: a review
Philosophical Transactions of the Royal Society A: Mathematical Physical and Engineering Sciences, 2020Co-Authors: Jérôme Thiebot, Simon P Neill, Daniel Coles, Anne-claire Bennis, Nicolas Guillou, Sylvain Guillou, Matthew PiggottAbstract:The tides are a predictable, renewable, source of Energy that if harnessed, can provide significant levels of electricity generation. Alderney Race, with current speeds that exceed 5 m/s during spring tides, is one of the most concentrated regions of Tidal Energy in the world, with the upper bound resource estimated at 5.1 GW. Due to its significance, the Alderney Race is frequently used for model case studies of Tidal Energy conversion, and here we review these model applications and outcomes. We examine a range of temporal and spatial modelling scales, from regional models applied to resource assessment and characterisation, to more detailed models that include Energy extraction and array optimization. We also examine a range of physical processes that influence the Tidal Energy resource, including the role of waves and turbulence in Tidal Energy resource assessment and loadings on turbines. The review discusses model validation, and covers a range of numerical modelling approaches, from 2D to 3D Tidal models, two-way coupled wave-tide models, Large Eddy Simulation (LES) models, and the application of optimization techniques. The review contains guidance on model approaches and sources of data that can be used for future studies of the Alderney Race, or translated to other Tidal Energy regions.

Tidal Energy extraction in three-dimensional ocean models
Renewable Energy, 2017Co-Authors: Alice J. Goward Brown, Simon P Neill, Matt J LewisAbstract:Access to high performance computing has made 3-D modelling de rigueur for Tidal Energy resource assessments. Advances in computing resources and numerical model codes have enabled high resolution 3-D ocean models to be applied at basin scales, albeit at a much higher computational cost than the traditional 2-D modelling approach. Here, a comparison between 2-D and 3-D Tidal Energy extraction modelling techniques is undertaken within a 3-D modelling framework, and differences between the methods are examined from both resource and impact assessment perspectives. Through a series of numerical experiments using the Regional Ocean Modeling System (ROMS), it is shown that 3-D Tidal Energy extraction can be successfully incorporated in a regional ocean model of the Pentland Firth - one of the top regions in the world for Tidal stream Energy development. We demonstrate that resolving 3-D flow is important for reducing uncertainty in environmental resource assessments. Further, our results show that 2-D Tidal Energy extraction methods lead to a misrepresentation of the velocity profile when applied to 3-D models, demonstrating the importance of resolving 3-D flows in the vicinity of Tidal arrays.

Tidal Energy leasing and Tidal phasing
Renewable Energy, 2016Co-Authors: Simon P Neill, M. Reza Hashemi, Matt J LewisAbstract:In addition to technical and economic constraints, Tidal Energy leasing is generally governed by demand for sites which contain the highest Tidal streams, and does not take into account the phase relationship (i.e. the time lag) between sites. Here, the outputs of a three-dimensional Tidal model are analysed to demonstrate that there is minimal phase diversity among the high Tidal stream regions of the NW European shelf seas. It is therefore possible, under the current leasing system, that the electricity produced by the first generation of Tidal stream arrays will similarly be in phase. Extending the analysis to lower Tidal stream regions, we demonstrate that these lower Energy sites offer more potential for phase diversity, with a mean phase difference of 1.25 h, compared to the phase of high Energy sites, and hence more scope for supplying firm power to the electricity grid. We therefore suggest that a state-led leasing strategy, favouring the development of sites which are complementary in phase, and not simply sites which experience the highest current speeds, would encourage a sustainable Tidal Energy industry.
