TL;DR: In this article, the development of wave energy utilization since the 1970s is discussed, with a focus on the characterization of the wave energy resource; theoretical background, with especial relevance to hydrodynamics of wave absorption and control; how a large range of devices kept being proposed and studied, and how such devices can be organized into classes; the conception, design, model-testing, construction and deployment into real sea of prototypes.
Abstract: Sea wave energy is being increasingly regarded in many countries as a major and promising resource. The paper deals with the development of wave energy utilization since the 1970s. Several topics are addressed: the characterization of the wave energy resource; theoretical background, with especial relevance to hydrodynamics of wave energy absorption and control; how a large range of devices kept being proposed and studied, and how such devices can be organized into classes; the conception, design, model-testing, construction and deployment into real sea of prototypes; and the development of specific equipment (air and water turbines, high-pressure hydraulics, linear electrical generators) and mooring systems.

TL;DR: In this paper, a review of wave energy converter (WEC) technology is presented, focusing on work being undertaken within the United Kingdom, and some of the control strategies to enhance the efficiency of point absorber-type WECs.
Abstract: Ocean waves are a huge, largely untapped energy resource, and the potential for extracting energy from waves is considerable. Research in this area is driven by the need to meet renewable energy targets, but is relatively immature compared to other renewable energy technologies. This review introduces the general status of wave energy and evaluates the device types that represent current wave energy converter (WEC) technology, particularly focusing on work being undertaken within the United Kingdom. The possible power take-off systems are identified, followed by a consideration of some of the control strategies to enhance the efficiency of point absorber-type WECs. There is a lack of convergence on the best method of extracting energy from the waves and, although previous innovation has generally focused on the concept and design of the primary interface, questions arise concerning how best to optimize the powertrain. This article concludes with some suggestions of future developments.

TL;DR: The Global Energy Assessment (GEA) as mentioned in this paper brings together over 300 international researchers to provide an independent, scientifically based, integrated and policy-relevant analysis of current and emerging energy issues and options.
Abstract: The Global Energy Assessment (GEA) brings together over 300 international researchers to provide an independent, scientifically based, integrated and policy-relevant analysis of current and emerging energy issues and options. It has been peer-reviewed anonymously by an additional 200 international experts. The GEA assesses the major global challenges for sustainable development and their linkages to energy; the technologies and resources available for providing energy services; future energy systems that address the major challenges; and the policies and other measures that are needed to realize transformational change toward sustainable energy futures. The GEA goes beyond existing studies on energy issues by presenting a comprehensive and integrated analysis of energy chalenges, opportunities and strategies, for developing, industrialized and emerging economies. This volume is a invaluable resource for energy specialists and technologists in all sectors (academia, industry and government) as well as policymakers, development economists and practitioners in international organizations and national governments.

TL;DR: In this article, a complete analysis of the wave energy technology is presented, starting with the characterisation of this global resource in which the most suitable places to be exploited are showed, and the classification of the different types of wave energy converters in according to several features.
Abstract: The wave energy is having more and more interest and support as a promising renewable resource to replace part of the energy supply, although it is still immature compared to other renewable technologies. This work presents a complete analysis of the wave energy technology, starting with the characterisation of this global resource in which the most suitable places to be exploited are showed, and the classification of the different types of wave energy converters in according to several features. It is also described in detail each of the stages that are part in the energy conversion, that is, from the capture of the energy from the waves to the extraction of a proper electrical signal to be injected to the grid. Likewise, existing offshore energy transmission alternatives and possible layouts are described.

TL;DR: In this article, a comparison of methods for the calculation of the hydrodynamic characteristics of arrays of wave power devices is presented, in particular, the plane-wave approximation and an exact multiple scattering formulation have been used to compute exciting wave forces, hydrodynam coefficients and q factors for arrays of interacting wave powers devices.

TL;DR: Work on wave energy within the UK began in the early 1970s with a report from the Central Policy Review Staff, which identified the Government's responsibility to assess a wide range of possible energy options to ensure security of energy supplies as mentioned in this paper.
Abstract: Work on wave energy within the UK began in the early 1970s with a report from the Central Policy Review Staff, which identified the Government's responsibility to assess a wide range of possible energy options to ensure security of energy supplies The UK Department of Energy (DEn) funded extensive research into wave energy during the period 1974 to 1983 under its Wave Energy Programme The programme objectives were to establish the feasibility of extracting energy from ocean waves and to estimate the cost of energy if used on a large scale to supply UK needs The latter objective was addressed by setting a design aim to establish a 2 GW wave power station situated off South Uist in the Outer Hebrides of Scotland During the course of the programme a large number of devices were considered but found to be uneconomic (ETSU, 1985) With hindsight, the objective of that programme was over ambitious and resulted in massive devices, with corresponding high capital and generating costs

Abstract: SYNOPSIS The energy crises of the 'seventies threatened the standard of living of the developed countries and led to vigorous research into a variety of possible replacements for fossil fuel—particularly for oil. Sea waves were one of the more novel of the renewable resources which were taken seriously. After a brief historical introduction the paper discusses wave climate, the types of device, means of reaction, power conversion mechanisms and survival techniques. The final section gives some advice to potential customers. The paper is based on a presentation made at the 10th Anniversary Conference of the Philippines National Academy of Science and Technology in July 1988.
