Greening island: Renewable energies mix to satisfy electrical needs of Pantelleria in Mediterranean sea
In this article the authors analyze the renewable mix in order to satisfy the energy needs of a real island in the Mediterranean sea, Pantelleria, which represents an optimal starting point to increase the production of electrical energy from renewable sources in minor islands. In this text are exposed different alternative sources, such as solar, wind and wave energy. Moreover, it is exposed a project of an innovative conversion device proposed by Department of Energy of University of Palermo, compared to a different one proposed by Politecnico di Torino. The procedures applied in the present article, as well as the main equations used, are the result of previous applications made in diffe…
Assessment of Renewable Sources for the Energy Consumption in Malta in the Mediterranean Sea
The main purpose of this paper is to analyze the energy production in the Maltese islands, focusing on the employment of renewable energies in order to increase their energy independence. The main renewable source here proposed is wave energy: thanks to a strategic position, Malta will be able to produce electrical energy using an innovative type of Wave Energy Converter (WEC) based on the prototype of a linear generator realized by University of Palermo. The use of this new technology will be able to cut down the electrical energy production from traditional power plants and, consequently, the greenhouse gas emissions (GHG). Wave energy source and off-shore photovoltaic (PV) technology are…
Renewable energy sources to fulfill the global energy needs of a country: The case study of Malta in Mediterranean Sea
The paper shows the advantages using different energy resources for the islands of Malta. Moreover, this work is focused on the analysis of the wave energy potential along Malta's coasts. This important resource can be exploited to produce electrical energy using an innovative Point Absorber based on a new generator prototype realized by University of Palermo. The use of renewable source will reduce greenhouses emissions and increase the energy independence of Malta. The procedures applied in the present article, as well as the main equations used, are the result of previous applications made in different technical fields that show a good replicability [1]-[7].
Near zero energy island with sea wave energy: The case study of Pantelleria in Mediterranean Sea
In this paper the authors present a study of the transition of an energy generation system for a real MV/LV distribution system from one that is "fuel-based" to a "renewables-based" system in particular from sea wave energy, using the data acquired from an innovative generator prototype realized by University of Palermo. The study is carried out for a real islanded network located in the Island of Pantelleria (Mediterranean Sea). The procedures applied in the present article, as well as the main equations used, are the result of previous applications made in different technical fields that show a good replicability [1]-[7].

The paper is focused on the analysis of the electrical energy sector in the Maltese islands, focusing on the employment of Renewable Energies in order to increase its energy independence. The main renewable source here proposed is wave energy: thanks to its strategic position, Malta will be able to generate electrical energy through the use of an innovative type of Wave Energy Converter (WEC) based on the prototype of linear generator designed and developed by the University of Palermo. This new technology will be able to cut down the electrical energy production from traditional power plants and, consequently, the greenhouse gas emissions (GHG).

A Magnetohydrodynamic Auxiliary Propulsion system for docking assistance of autonomous vehicle
In this article we present an approach to the description of Magnetohydrodynamic Auxiliary Propulsion system for docking assistance of autonomous vehicle. Preliminarily, an analytical model which includes an electromagnetic model and a thermal model is presented. Successively, in order to move beyond the analytical model, a 3-D MHD modeling tool and a Runge Kutta method based solver are presented and they are used to investigate an alternative MHD solutions. Some numerical analysis are given
The helicoidal magnetic generator
Recently helicoidal generator for the exploitation of sea wave energy has been proposed. This device can convert both the vertical and rotational movement of seawaves. The electrical energy generated by such a device must be converted and conditioned in order to match the instantaneous utility requirements and a power link from the sea to an interconnection is needed. In this paper, the authors propose a mathematical model of this device and preliminarily present a prototype of the machine.
Hydrogen Production from Sea Wave for Alternative Energy Vehicles for Public Transport in Trapani (Italy)
The coupling of renewable energy and hydrogen technologies represents in the mid-term a very interesting way to match the tasks of increasing the reliable exploitation of wind and sea wave energy and introducing clean technologies in the transportation sector. This paper presents two different feasibility studies: the first proposes two plants based on wind and sea wave resource for the production, storage and distribution of hydrogen for public transportation facilities in the West Sicily; the second applies the same approach to Pantelleria (a smaller island), including also some indications about solar resource. In both cases, all buses will be equipped with fuel-cells. A first economic a…
