Can be standarized for alle ferries and port terminals
Transfer of >1 MW power
Increase time for energy transfer by fast connection and late
disconnection
Improved safety during operation as no mecanical connection is
established
Reduced maintenance cost
Fully automated system
Combined with auto mooring the propulsion can be shut down during
docking
Shore connection to AC or DC or both as standard

Technology demonstration
FERRY OPERATIONS
• The first ferry that can operate seamless between different modes of operation
– Diesel electric mode (as original)
– A multiple of hybrid modes with or without charging from shore
– Electrical mode with charging renewable energy from shore (no fossile fuel used)
– Testing ongoing in normal operation for over 1 year
– Next step is full scale implementation of inductive charging
– Onshore energy storage and grid connection

Conclusions
• Results from operations concludes the benefits of energy storage and hybrid operations including
plug-in solutions
– Electrical plug-in operation reduce operational cost and zero emission can be achived with renewable energy
– Hybrid plug-in hybrid operation is attractive for many ships due to flexibility and fuel saving and reduced
emissions
– Hybrid operation with variable operational profiles reduce operational cost and emissions with the right
configuration and operational profile
• Energy storage systems(ESS) has documented reliable and safe operation and new class notations
are already in place
• Understanding the operational needs is critical for design of the ESS and the overall control
