“…The value of the power coefficient is strongly dependent on the type of tidal stream device used for energy conversion and on the specific characteristics of the installed device. The value of the 𝐶 𝑃 assumed in this work is based on experimental data observed in towing tank tests on a small model of a 3bladed hydrokinetic turbine, as reported in [37].

This work is a preliminary study to find some sites for the potential use of tidal stream energy and their associated currents in the Chubut coast. In addition, an evaluation of the energy resource of the Chubut Gulfs is made. The possibility of energetic utilization of the tides is achieved by transforming the displacement movement into a rotation movement by means of a hydrokinetic turbine. The energy can be extracted analogously to that of wind energy; therefore, it is not necessary to build a dam, avoiding the environmental and economic disadvantages it represents. Even though the results presented in this paper have significantly improved our understanding of tidal dynamics in this region, the collection of more observations, particularly in the interior and at the mouths of the Gulfs, is necessary to develop and fully shape tidal potential into power generation in the region.

State of the Art and Perspectives of Wave Energy in the Mediterranean Sea: Backstage of ISWEC

According to the European Commission, sea waves have a great potential as renewable energy source. Despite wave energy technology is a field in continuous development, it is not yet competitive with the other renewables, due to the small quantities of devices sold, most of them being prototypal solutions at level. So far, various Wave Energy Converter concepts have been developed and some of them tested in full scale. The most recurrent test environment is the North Atlantic Ocean, which possesses high energy potential. The Mediterranean Sea on the other hand is less energetic, but also possesses less dangerous extreme conditions. It represents a favorable starting point to develop technologies that later will be scaled up to more powerful sites. This article illustrates the wave energy potential of the Mediterranean and analyses the wave energy converters engineered according to sea states characteristic of the Mediterranean Sea. Focus is brought to the Inertial Sea Wave Energy Converter (ISWEC) technology, which is one of the few Mediterranean concept to have reached Technology Readiness Level (TRL) 7. The article will document the deployment and the following open sea test campaign of a full-scale prototype off the shore of Pantelleria Island, Italy.

This study proposes the design of a tidal turbine station keeping system based on the adoption of a tensioned mooring system. Damping is introduced to investigate its effect on the reduction in the peak load experienced by tidal turbines during their operational lives in high-energy wave–current environments. A neutrally buoyant turbine is supported using a tensioned cable-based mooring system, where tension is introduced using a buoy fully submersed in water. The loads on the turbine rotor blades and buoy are calculated using a wave and current-coupled model. A modelling algorithm is proposed based on inverted pendulums, which respond to various sea state conditions, to study the behaviour of the system as well as the loads on blades. The results indicate that the tensioned mooring system reduces the peak thrust on the turbine and validates the applicability of the model.
