ETRERA_2020 (Empowering Trans-Mediterranean Renewable Energy Research Alliance For Europe 2020 Challenges) is a EU project aimed at tackling the future energy needs by creating a Euro-Mediterranean research alliance for the development of a RDI network on Renewable Energy Sources – RES technologies and for improving Research-Industry cooperation. It targets the following technologies: wind, photovoltaic, solar thermal, hydrogen and fuel cells, and smart grid. The final aim of ETRERA_2020 is the set-up of a Meta-Cluster, focused on the RES innovation.
