“…The accentuated influence of the turbine damping on the device performance highlights the importance of the appropriate selection of the turbine damping when designing an OWC device, as shown previously by, e.g., [49,[74][75][76][77][78]. For the wave conditions and damping coefficient values tested, the largest damping coefficient (B * = 64.10) is the one showing, generally, the highest values of C WR .…”

Abstract:The growth of the offshore wind industry in the last couple of decades has made this technology a key player in the maritime sector. The sustainable development of the offshore wind sector is crucial for this to consolidate within a global scenario of climate change and increasing threats to the marine environment. In this context, multipurpose platforms have been proposed as a sustainable approach to harnessing different marine resources and combining their use under the same platform. Hybrid wind-wave systems are a type of multipurpose platform where a single platform combines the exploitation of offshore wind and wave energy. In particular, this paper deals with a novel hybrid wind-wave system that integrates an oscillating water column wave energy converter with an offshore wind turbine on a jacket-frame substructure. The main objective of this paper is to characterise the hydrodynamic response of the WEC sub-system of this hybrid energy converter. A 1:50 scale model was tested under regular and irregular waves to characterise the hydrodynamic response of the WEC sub-system. The results from this analysis lead to the proof of concept of this novel hybrid system; but additionally, to characterising its behaviour and interaction with the wave field, which is a requirement for fully understanding the benefits of hybrid systems.

“…In a further step, other authors have been extending the air expansion/compression problem inside the chamber [4]. Finally, a method of geometric control to maximize the efficiency of power extraction has been also shown [1], as well as the application of artificial intelligence to predict the OWC efficiency, [5].…”

a b s t r a c tOscillating water column (OWC) are devices for wave energy extraction equipped with turbines for energy conversion. The purpose of the present work is to study the thermodynamic of a real gas flow through the turbine and its differences with respect to the ideal gas hypothesis, with the final goal to be applied to OWC systems. The effect of moisture in the air chamber of the OWC entails variations on the atmospheric conditions near the turbine, modifying its performance and efficiency. In this work we study the influence of humid air in the performance of the turbine. Experimental work is carried out and a real gas model is asserted, in order to take a first approach to quantify the extent of influence of the airewater vapour mixture in the turbine performance. The application of a real gas model and the experimental study confirmed the deviations of the turbine performance from the expected values depending on flow rate, moisture and temperature.

“…Estableciendo estas tecnologías en una etapa de desarrollo e investigación inicial [47,[55][56][57][58][59][60][61], hace difícil estimar los costos y el rendimiento de los dispositivos e instalaciones. Además, la mayor parte de los estudios económicos actuales están sobre simplificados, y esto podría crear inseguridad en los inversionistas [62].…”

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.
