Ports are a key element within the contemporary supply chain; the so called “green logistics” are today of primary interest, taking into consideration the increased pressure for environmentally friendly shipping operations. Emissions from shipping due to the combustion of marine fuels with high sulphur content significantly contribute to air pollution in the form of sulphur dioxide and particulate matters. These emissions constitute, undoubtedly, severe health hazards for the population of all surrounding areas; cold Ironing is campaigned as one of the main strategies in the gradual decrease of emissions in port areas.
The concept of zero emissions’ port is referred to a port powered mainly from renewable energy sources in order to sufficiently accommodate its power requirements and simultaneously reduce air emissions, mainly by using the concept of cold ironing. Several renewable forms of energy and their application to port operation will be discussed; the concept of smart grid is used in order to facilitate the use of several and different renewable forms of energy and be able to monitor and control all the demand and distribution at the same time. In this analysis, by taking advantage of existing experience in energy management associated with smart grids of renewable energy and the power needs of a vessel in a port, a dedicated methodological framework is put forward in order to effectively handle the varying energy demands of a zero emissions port.
