Tidal current energy resource assessment: the Strait of Messina test case

In this paper we present the assessment of tidal energy resource for the Strait of Messina. After considering both the constraints (geometric, site specific and operational) and the current potential of the area, the energy resource has been evaluated through the application of the method of energy flow and the method of farm. Four different converter devices have been considered: GEM, Kobold, MCT SeaGen and Verdant Power. Their performances have been compared assuming a theoretical common maximum power and considering the total amount of tidal energy produced in a number of potential selected locations. The GEM, Kobold and MCT SeaGen turbines reveal to be very competitive and effective. This analysis is particularly significant as at present, an extensive and accurate current assessment for the Italian seas is not yet available.
