Design of Bilateral Switched Reluctance Linear Generator to Convert Wave Energy: Case Study in Sicily

Near 100% Renewable Island with sea wave energy. The case study of Pantelleria in Mediterranean sea

The first aim of this work is to explore the possibility of the transition of a real islanded network from one that is “fuel-based” to a “renewable-based” one. This transition is analysed for the real MV/LV distribution system of the island of Pantelleria, in the Mediterranean Sea. Particularly, this work is focused on a Renewable source nowadays totally unused: wave energy. Thanks to the innovative generator prototype designed by Department of Energy of University of Palermo (Italy), wave energy is able to represent a primary source for the production of electric energy in the Mediterranean islands. The procedures applied in the present article, as well as the main equations used, are the …

Energy savings through integration of the illumination natural and artificial, using a system of automatic dimming:Case study

The reduction of electrical energy consumption in buildings is a subject of great interest in the international scientific community. In buildings with a lot of available natural light, designed with large glazed surfaces, the artificial lighting system is often oversized and cannot be divided into segments to meet lighting demands during daylight hours. This article presents an experimental study, conducted in a university lecture hall that has a glazed surface covering the whole wall at one end, which provides a level of internal illumination that is only sufficient for the area next to the window itself, even when the outside lighting conditions are very bright. It is therefore necessary…

The use of hydrogen in residential sector: Economic aspects and environmental benefits

Experimental results of a low cost weather buoy

Renewable energy sources for energy consumption needs of Malta Island in Mediterranean sea

The main purpose of this paper is to analyse the energetic condition of the Maltese islands and its electrical energy production, 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 produce electrical energy using an innovative type of Wave Energy Converter (WEC) based on the prototype of 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 gases emissions (GHG). The procedures applied in …

Sea wave energy to produce Hydrogen 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 introducing clean technologies in the transportation sector. This paper presents a feasibility study of two plants for the production, storage and distribution of hydrogen for Public transportation facilities in the West Sicily. In these plants the energy needs for the process is generated by a wind farm and/or a sea wave farm. All the buses will be equipped with a fuel-cell. A first economic analysis is presented together with the assessment of the avoidable greenhouse gas emissions during the ope…
