It's electric: Stena Line to add batteries to car/passenger ferry
MARCH 2, 2018 — Leading European ferry operator Stena Line has signed a
contract with Callenberg Technology Group, Gothenburg, Sweden, that will
see batteries with a capacity of 1 MWh installed on ROPAX ferry Stena
Jutlandica.
The 550 car, 1,500 passenger ferry operates between Gothenburg, Sweden,
and Frederikshavn, Denmark.
Before the summer, says Stena Line, battery power in port operation will
become a reality. However, its future target for battery operation is to
be able to navigate the vessel for 50 nautical miles.
"Sustainability is very high on our agenda and we are constantly
evaluating new ways to reduce our impact on the environment," says Stena
Line CEO Niclas Mårtensson. "From 2015, for example, methanol is part of
the fuel mix on Stena Germanica, which operates between Gothenburg and
Kiel, and we also run around 300 different energy saving projects. As
both the size and cost of batteries decrease, battery operation becomes
a very exciting alternative to traditional fuels for shipping, as
emissions to air can be completely eliminated"
The three-phase battery project will be completed step by step. The
first phase will see battery power used for bow thrusters and
maneuvering when berthing in port.
The second phase, which is expected to be completed in 2022, will extend
battery operation to the propellers, so that Stena Jutlandica can
operate on electricity within around 10 nautical miles, equal to the
distance between Göteborg and Vinga Lighthouse.
The third phase, which is expected to be completed in 2030, will expand
the battery capacity to enable operation on electricity for about 50
nautical miles — the distance between Gothenburg and Frederikshavn.
The objective of accomplishing this in several steps, says Stena Line,
is to test and gather knowledge about electrical operation along the
way. If the project is successful, battery operation may also be
applicable to other vessels in the Stena Line fleet of 38 vessels.
The technical solutions are being developed together with Stena Teknik,
which cooperates with the academic world, authorities and various
suppliers.
According to Stena Line spokesman Jesper Waltersson, the total project
investment is SEK25 million (or about $3 million at current exchange
rates), with 50% of the funding being provided by the EU and Swedish
Transport Administration.
The technology tested is based on plug-in hybrid technology. The
batteries are charged when the ship is connected to shore power, which
is also an important focus area on clean energy, but can also be charged
while operating the ship's generators.
Every year Stena Lines moves about 7 million freight units, 2 million
passengers and 1.5 million cars. Stena Line employs approximately 5,500
staff and crew and 2015 had a turnover of about SEK14 billion.
