The MATS project aims at promoting the exploitation of concentrated solar energy through small and middle scale facilities, suitable to fulfil local requirements of power and heat, and easy to back-up with the locally already available, or expressly producible, renewable fuels. The implementation of the project will allow to test the CSP (Concentrating Solar Power) technology in a very advantageous location with regard to the solar radiation rate as an example for the diffusion of this technology in other Mediterranean Countries. Besides, it will represent the start-up for a development of specialized local industries. More in detail, the MATS project is focused on the innovative CSP technology developed by ENEA as an improvement of its Solar Thermodynamic technology based on molten salts as heat transfer fluid. This technology, referred as TREBIOS, allows combined heat and power production from solar source integrated with renewable fuels, such as biomass, biogas, industrial residues etc.
