This is investigated by modeling zero emission energy storage devices (ESDs) in the power and propulsion configuration of a benchmark urban ferry. This benchmark ferry provides the speed profile for input to the baseline model. Three ESD configurations for providing power and propulsion are identified: the Full ESD configuration, the ideal peak shaving configuration and the on-off hybrid configuration. A selection process, which uses a baseline model to compare the power and energy requirements, is applied to identify the most promising configuration. Then, using a weight estimate for the total power and propulsion configuration, the ESD requirements are compared in a Ragone chart, which plots the specific power and energy of the ESD. This comparison shows that the full ESD configuration with a battery as the ESD has the highest potential for the benchmark urban ferry. This configuration does not emit emissions locally. The full ESD configuration with battery is modeled in more detail, using the operational profile of the benchmark urban ferry as input. This configuration, however, is unable to sail the profile for a day due to the battery capacity being too small. Additional changes are proposed related to the battery technology, operational profile, and hull dimensions to allow for more battery capacity. When the battery technology is improved and changes are implemented in either the operational profile or the hull dimensions, the ferry is able to sail the profile for a full day, emitting no harmful, polluting emissions, at least locally.
