Electricity – not new to shipping
Some 130 years ago on the
Spree River in Berlin,
Siemens tested its first
electric boat, which was
intended to operate as a
kind of water taxi back in
1886.
The Elektra could carry 25
passengers at a speed of 8
knots.

Step 1 : Containerized Energy Storage System
• First step in company long term battery plan.
• Installation Q2 2018 of Energy Storage System of about 1
MWh capacity and 3MW power.
• This solution could fit any ship. No limit of deck area.
• Charging by green electricity in port (30 mins) and by ships
aux engines.
• The ESS system to be used as
• Replace two aux engines to power bow thrusters during Stena Jutlandica - Built 1996 (RoPax)
maneuvering Passenger capacity 1,500
Lanemeters 2,750
• Peak shaver for aux engines at normal seagoing operation 182,5 m LOA 28 m beam
• Safety back-up to prevent black-outs in narrow waters About 1,400 voyages / year
Aux engines 4*1,540 kW
• It will lower emission, noise and maintenance + add
goodwill.
• Total investment €2,5 mill. Supported by EU and Swedish
Swedish Transport Administration.
• Suppliers Corvus + Callenberg Technology Group.
• Potential saving of 1,500 mt CO2/year.
Step 2: ME Plug-in hybrid • Conversion of existing diesel-mechanical vessel Stena Jutlandica. • Battery operation replacing 2/4 main engines. • For operation in port area and coastal areas up to 10 nm. • Optimise use of main engines under operation (Peak shaving), reduce noise and emissions to air – especially in Stena Jutlandica - Built 1996 (RoPax) urban areas. Passengers 1,500 Lanemeters 2,750 • Battery capacity about 20 MWh (Lithium jon) with 8MW Main engines 4*MAN 9L48/54 tot. 25,920 kW. power. • Remove existing 50% of the diesel power and add 8 MW electric drive - or keep existing arrangement and add 8 MW electric drive to the propeller shaft. • Charging in abt. one hour with 10MW shore side electricity (currently max 2,5 MW). • Budget estimated €25 mill. Can save up to 50% of emissions. • Potential start 2020/2022
Step 3 : Full electric
• Full electric short-sea RoPax.
• Conversion or more likely N/B.
• Battery capacity of 50 MWh, charging in 2-3 hours with 10 MW.
• Operation range of about 50 nautical miles.
• Ambition for 2030 - a fossil free route Göteborg-Fredrikshavn.
• When a capacity and range of about 60 nm is achieved about 5-6
of Stena Lines 21 routes can potentially be electrified.
• Supporting initiatives:
• Minor stakeholder in future battery producer “Northvolt” Short routes with potential in falling order
• R&D on battery recycling through Stena Recycling Cairnryan – Belfast 40nm 2 ship
• Participation in Swedish Electric Mobility Lab Gothenburg – Fredrikshavn 52nm 2 ship
Fishguard – Rosslare 58nm 1 ship
Trelleborg – Sassnitz 62nm 1 ship
Holyhead – Dublin 62nm 2 ship
Varberg – Grenå 65nm 1 ship
9 out of 38 ships – 24%
Concept ship - STENA ELEKTRA
• All electric battery powered RoPax vessel
with min. operational range 4 hours at 20
knots
• Hybrid alternative prepared for installation
of fuel cells, methanol or gas.
• Extensive use of light weight material to
save energy
• Flexible module based passenger areas for
scalable solutions
• Seasonal based passenger capacity 400 –
1,500 persons
• 3,000 lane meters with capacity for 200
trucks
• Quick loading and discharge with double
stern quay side ramps. Stern loading
only also enables an efficient hull form
• Reduced energy consumption by 50% per
unit.
• Autonomy operational support for
increased safety
