The overall objective is to develop a common strategy for the deployment of renewable energy and energy efficiency, strengthening cooperation platform between the two countries, Italy and Tunisia. In order to implement the use of sustainable energy microsystems, thanks to advanced technology capable of generating and storing more energy from renewable sources, the project involves the development and the creation of 2 devices of sustainable energy microsystems (1 in Tunisia and 1 in Valderice) to generate and store electricity from various renewable sources (solar thermal, photovoltaic, mini-wind) and storage systems (hydrogen, battery-traditional and innovative).
