The 3-year M-TES project “Metallic phase change material-composites for Thermal Energy management” addresses the energy saving issue by tackling heat recovery and managing in processes which produce or re-use energy in the form of heat. The overall objective is to design new metallic materials for Thermal Energy Storage and Thermal energy Management by using the heat stored or released during the phase change from solid to liquid of a metal. In the same material, but in different portions, structural and phase change metals will be combined, obtaining a composite metallic material. Care will be taken to avoid critical raw materials, and to use low-cost manufacturing processes. Optimization of composition and processing will be addressed to achieve adequate performances for future applications in energy and industrial fields.
