7 The Future - Hybrid Ferries Reasons for Hybrid Propulsion System Reducing Emissions Possibly zero emissions in harbour as vessel will be powered by batteries or shore supply while in harbour mode Energy Savings Fuel Savings, on existing vessels there are periods of low load running, which can increase SFOC by 5-10% Reduced Operating Costs Reduced noise when operating on batteries Flexible and efficient operation, excellent redundancy Less Installed Power by optimising machinery selection The batteries onboard the vessel could be charged overnight from a shore supply, could be a wind turbine or from a source of renewable power (Hydro or Wind Farm).

19 INNOVATIVE SHIP POWER DISTRIBUTION NETWORK The hybrid diesel electric propulsion system will use at least 20% less fuel than a diesel mechanical propulsion system operating at design speed and with the vessel fully loaded, resulting in at least a 20% reduction in CO2 emitted by the Vessel. At lower speeds and light loaded conditions; greater fuel savings can be achieved and a greater reduction in CO2 emissions. On days with reduced numbers of crossings it will be possible to operated on batteries only for some crossings. In port the vessel is capable of operating on batteries only, zero emissions.
