“…Debido a que los costos de inversión requeridos para la puesta en marcha son elevados, es útil disponer de estimaciones de potencia de salida [35]{Reikard, 2015, Simulating and forecasting ocean wave energy in western Canada}, que considere localidades en donde se emplazará y características morfológicas de la costa y del suelo marino, ya que dependiendo de éstas la distribución energética se presenta de manera particular [31]. Además, otros focos que no han sido abordados son la incertidumbre sobre el impacto generado por las granjas de olas en el mar y la costa [36][37][38][39][40][41][42][43][44][45][46] o el hecho de que se considere poco rentable [32].…”

RESUMENLas energías marinas están siendo cada vez más consideradas en el mundo como un recurso importante y prometedor. Unas de ellas, la energía undimotriz, utiliza la energía mecánica proveniente del movimiento de las olas del mar para la generación de electricidad. Este artículo presenta una revisión bibliográfica de las siguientes temáticas: situación energética mundial, beneficios en la recolección de energía undimotriz y tipos de convertidores utilizados actualmente. Chile presenta una situación energética que requiere el uso de nuevas tecnologías. La región de Tarapacá posee un potencial considerable de generación de electricidad por medio de las olas, por lo que el aprovechamiento de este tipo de energía se presenta como una opción altamente vinculante con las industrias que forman parte del motor económico de la región.Palabras clave: Energía, ERNC, energía undimotriz, potencial undimotriz, convertidor undimotriz, potencial eléctrico, fomento productivo, región de Tarapacá, Chile.

“…Only a small number of studies consider the environmental impact of such devices. To date, the impact of wave farms on wave climate has mainly been modelled numerically using wave propagation models such as mild-slope, Boussinesq, and Spectral Wave models [17] (examples include [18][19][20][21][22][23][24][25][26][27][28]). Within these studies, individual devices or entire wave farms are usually represented using partially transmitting obstacles, which do not represent the full hydrodynamic behaviour of the WEC.…”

Wave energy converters (WECs) inherently extract energy from incident waves. For wave energy to become a significant power provider in the future, large farms of WECs will be required. This scale of energy extraction will increase the potential for changes in the local wave field and coastal environment. Assessment of these effects is necessary to inform decisions on the layout of wave farms for optimum power output and minimum environmental impact, as well as on potential site selection. An experimental campaign to map, at high resolution, the wave field variation around arrays of 5 oscillating water column WECs and a methodology for extracting scattered and radiated waves is presented. The results highlight the importance of accounting for the full extent of the WEC behavior when assessing impacts on the wave field. The effect of radiated waves on the wave field is not immediately apparent when considering changes to the entire wave spectrum, nor when observing changes in wave climate due to scattered and radiated waves superimposed together. The results show that radiated waves may account for up to 50% of the effects on wave climate in the near field in particular operating conditions.

“…Nevertheless, there are some barriers that may hinder the development of marine energies, such as the early stage of development of the technologies [1][2][3][4][5][6][7][8][9][10][11], high costs involved [12][13][14][15][16] or uncertainties regarding the environmental impacts [17][18][19][20][21][22][23][24][25][26][27]. Among the different alternatives of ocean energy, this work focuses on two of them: Offshore wind and wave energy.…”

Abstract:Wave energy is one of the most promising alternatives to fossil fuels due to the enormous available resource; however, its development may be slowed as it is often regarded as uneconomical. The largest cost reductions are expected to be obtained through economies of scale and technological progress. In this sense, the incorporation of wave energy systems into offshore wind energy farms is an opportunity to foster the development of wave energy. The synergies between both renewables can be realised through these co-located energy farms and, thus, some challenges of offshore wind energy can be met. Among them, this paper focuses on the longer non-operational periods of offshore wind turbines-relative to their onshore counterparts-typically caused by delays in maintenance due to the harsh marine conditions. Co-located wave energy converters would act as a barrier extracting energy from the waves and resulting in a shielding effect over the wind farm. On this basis, the aim of this paper is to analyse wave energy economics in a holistic way, as well as the synergies between wave and offshore wind energy, focusing on the shadow effect and the associated increase in the accessibility to the wind turbines.
