Our ambition is
Emission Free
Ferries – we take
One Nautical Mile
at a Time.
We invest
responsively in
tomorrows
technology
Leading Towards
a Greener Future.

Scandlines HYBRID FERRY
The world’s largest hybrid ferry – 2.7 MWh battery bank / capacity of 364 cars
The system equals approx. 600 hybrid cars and can propel the vessels for 30 minutes
Reduce CO2 emissions by 15 % (approx. 15,000 tons CO2 yearly) when fully implemented
Large international recognition for this industry leading concept

Knowledge
Customers and employees
• Hybrid system generates large interest and positive feedback from customers • Large employee interest – especially among technical staff!
• More than 200 articles in Danish and German media and television coverage • Speakers at conferences and awards won • Growing political understand of ferries environmental improvement potential
• Reduce CO2 emissions by 15 % (approx. 15,000 tons CO2 yearly) when fully implemented on Puttgarden-Rødby
• Large potential among other diesel-electric ferry operators
• Lower fuel consumption • Lower maintenance cost • Smaller scrubber investment needed for 2015 environmental regulations
• Learning allows continued journey towards zero emission – accumulated experience with use of batteries a door opener
Benefits: Present
We are ready for zero emission by 2018 – and we have a clear roadmap on how to achieve this

What does it take – 3 potential roadblocks
12
Build competence in large scale shore side charging – 4 MWh to be charged to batteries in 15 minutes
Secure sufficient electrical infrastructure to harbors
• Partner with specialists to develop charging solution
• Current electrical grid to be investigated – most likely not sufficient to support large scale charging
Large scale charging Electrical infrastructure Investment payback needs to
be secured
Approx. 50-60 MEUR investment needed – need to secure realistic business case
• Understand funding available and finance possibilities
• Understand fixed link timeline and mitigate predatory pricing from state owned operator
Challenges Future
13
2013-2014 2015-2016 2017-2018 2019-2020
Introduce next generation hybrid vessels in 2015 with double capacity and lower emissions
Engine renewal program
Hull coating program
Develop “Plugin Hybrid” solution based on experience from Puttgarden-Rødby shore
side charging
Other improvement projects to lower electricity consumption
Rostock-Gedser
Puttgarden-Rødby
Develop “Plugin Hybrid” solution –
capability to charge in harbors
Ready for zero emissions operation –
100% electrical ferries Convert existing 4 double ended
ferries into hybrid ferries

Rostock-Gedser Puttgarden-Rødby
• Next generation is hybrid (2015) • Near Coast Zero Emission to be developed • Longer term: Combined battery and fuel
cell
• Conversion of current hybrid ferries into fully battery operated ferries
• Current electrical grid infrastructure needs to be upgraded
