The increasing energy demand in harbour areas, coupled with the need to reduce pollutant emissions, has led development of renewable energy-based polygeneration systems face carbon footprint ports and ships at berth. In this way, coming years, can be converted into modern hubs. From point view, paper presents a new dynamic simulation model for assessing optimizing economic impact ports. Here, sources designed connected national electricity natural gas grids include also alternative fuels (hydrogen, biomethane, etc.) thermal networks, as well different biomass fluxes (to exploited aims). Energy availability/demands near towns port buildings/infrastructures, on-shore power supply is are included assessments. Hourly weather data prices all considered carriers taken account hour by hour. A multi-objective optimization approach implemented considering indexes optimized. whole computer tool written MATLAB. For showing capability developed model, novel case study referred Naples (South-Italy) presented. several considered, including an anaerobic biodigester producing biogas from organic waste docked cruise ships. combined heat system (fed biogas) hub supplying absorption chiller. PV panels, marine generators included. conducted analysis, targets maximization self-consumption self-sufficiency minimum simple payback period. proposed effectively contribute decarbonization harmful emissions. Results showed that very high rate produced on-site (up 84%) facilities, ensuring independency utility grid (self-sufficiency index up 40%). By obtained results through simulation/optimization tool, design operating criteria achieved future hubs featured renewables bi-directional exchange between port.
