Ocean Energy


Book Description

Engineers’ dreams and fossil energy replacement schemes can come true. Man has been tapping the energy of the sea to provide power for his industries for centuries. Tidal energy combined with that of waves and marine winds rank among those most successfully put the work. Large scale plants are capital intensive but smaller ones, particularly built in China, have proven profitable. Since the initiation of the St Malo project in France, similar projects have gone into active service where methods have been devised to cut down on costs, new types of turbines developed and cost competitiveness considerably improved. Tidal power has enormous potential. The book reviews recent progress in extracting power from the ocean, surveys the history of tidal power harnessing and updates a prior publication by the author.




Marine Tidal and Wave Energy Converters


Book Description

The worldwide potential of electric power generation from marine tidal currents, waves, or offshore winds is enormous. The high load factor resulting from the fluid properties and the predictable resource characteristics make tidal and wave energy resources attractive and advantageous for power generation and advantageous when compared to other renewable energies. The technologies are just beginning to reach technical and economic viability to make them potential commercial power sources in the near future. While only a few small projects currently exist, the technology is advancing rapidly and has huge potential for generating bulk power. Moreover, international treaties related to climate control and dwindling fossil fuel resources have encouraged us to harness energy sustainably from such marine renewable sources. Several demonstrative projects have been scheduled to capture tidal and wave energies. A number of these projects have now reached a relatively mature stage and are close to completion. However, very little is known to the academic world about these technologies beyond the basics of their energy conversion principles. While research emphasis is more towards hydrodynamics and turbine design, very limited activities are witnessed in power conversion interface, control, and power quality aspects. Regarding this emerging and promising area of research, this book aims to present recent results, serving to promote successful marine renewable energies integration to the grid or to standalone microgrids.




Ocean Energy


Book Description

Energy from wave and tidal power is a key component of current policies for renewable sources of energy. This book provides the first comprehensive exploration of legal, economic, and social issues related to the emerging ocean energy industry, in particular wave and tidal energy technologies. This industry is rapidly developing, and considerable technical literature has developed around the technology. However, it is shown that challenges relating to regulation and policy are major impediments to industry development, and these aspects have not previously been sufficiently highlighted and studied. The book informs policymakers, industry participants, and researchers of the key issues in this developing field. Ocean energy is considered in the context of the blue economy and an industrialising ocean, and the topics covered include: development of policy (policy instruments, risk and delay in technology development); legal aspects (consenting processes, resource management, impact assessment); human interactions (conflicts, consultation, community benefits); and spatial planning of the marine environment. While offshore wind energy, sited in the oceans but not strictly derived from the ocean, is not the primary focus of the book, there is also discussion of the similarities and differences between offshore wind and wave and tidal power policy dimensions.




Renewable Energy from the Oceans


Book Description

There are many ways to harness the renewable and emissions-free energy available from the Earth's oceans. The technologies include wave energy, tidal and current energy, and energy from thermal and salinity gradients. In addition, offshore wind energy and marine (floating) solar arrays offer a possibility to exploit vast resources that are far larger than those available onshore. The potential capacities range from many hundreds of gigawatts to terawatts of generation. These technologies could contribute a significant part of the global electricity demand; they are particularly suitable for providing sustainable power to marine regions and island communities and nations.




Fundamentals of Ocean Renewable Energy


Book Description

Fundamentals of Ocean Renewable Energy: Generating Electricity from the Sea presents the basic concepts of mechanics and introduces the various technical aspects of ocean renewable energy. Contents follow a logical sequence, starting with hydrodynamics and then separately examining each conversion technology, with special focus on tidal energy, offshore wind and wave energy, as well as current and ocean thermal energy conversion (OTEC). The authors explore key topics for resource characterization and optimization, such as monitoring and measurement methods and ocean modeling. They also discuss the sustainability, planning, integration and distribution challenges for the implementation of these technologies, including co-location with other systems. Finally, case studies of ocean energy sites and devices allow for a better understanding of how ocean energy conversion works in real-world settings. This book is an invaluable resource for students at graduate and senior undergraduate level engineering (ocean, mechanical, and civil) and oceanography with prior knowledge of fluid mechanics and mechanics of materials. - Presents the fundamental physics and theory behind ocean energy systems, covering both oceanographic and engineering aspects of ocean energy - Explores the most widely adopted conversion technologies, including tidal, wave, offshore wind, ocean thermal and currents

Energy Harvesting


Book Description

Also called energy scavenging, energy harvesting captures, stores, and uses "clean" energy sources by employing interfaces, storage devices, and other units. Unlike conventional electric power generation systems, renewable energy harvesting does not use fossil fuels and the generation units can be decentralized, thereby significantly reducing transmission and distribution losses. But advanced technical methods must be developed to increase the efficiency of devices in harvesting energy from environmentally friendly, "green" resources and converting them into electrical energy. Recognizing this need, Energy Harvesting: Solar, Wind, and Ocean Energy Conversion Systems describes various energy harvesting technologies, different topologies, and many types of power electronic interfaces for stand-alone utilization or grid connection of energy harvesting applications. Along with providing all the necessary concepts and theoretical background, the authors develop simulation models throughout the text to build a practical understanding of system analysis and modeling. With a focus on solar energy, the first chapter discusses the I−V characteristics of photovoltaic (PV) systems, PV models and equivalent circuits, sun tracking systems, maximum power point tracking systems, shading effects, and power electronic interfaces for grid-connected and stand-alone PV systems. It also presents sizing criteria for applications and modern solar energy applications, including residential, vehicular, naval, and space applications. The next chapter reviews different types of wind turbines and electrical machines as well as various power electronic interfaces. After explaining the energy generation technologies, optimal operation principles, and possible utilization techniques of ocean tidal energy harvesting, the book explores near- and offshore approaches for harvesting the kinetic and potential energy of ocean waves. It also describes the required absorber, turbine, and generator types, along with the power electronic interfaces for grid connection and commercialized ocean wave energy conversion applications. The final chapter deals with closed, open, and hybrid-cycle ocean thermal energy conversion systems.
