The propose is to develop a virtual representation of the inland shipping system, that can be used for assessing the efficiency of zero emission strategies. This digital twin will represent the real system with all relevant components. The focus is on three main aspect: the individual vessels, the logistic chains and the infrastructure. Potential interventions will be considered ranging from the application of new technologies for individual vessels to policy measures for an entire shipping corridor. Future scenarios can be imposed on the digital twin and their efficiency can be evaluated for the right path towards zero emission shipping.
