Viking Line’s vessels serving the Turku route will reduce their emissions by 90 per cent when the company runs its vessels for a whole week for the first time solely on biogas, supplied by SEA-LNG member Gasum.  Starting today in celebration of Baltic Sea Day, Viking Glory and Viking Grace will demonstrate what the future looks like for the first green shipping corridor on the Baltic Sea.

The climate-smart Viking Glory and Viking Grace will only use liquefied biogas (LBG) as fuel from today until 4th September between Turku and Stockholm.  This action will reduce the vessels’ carbon dioxide emissions by 90 per cent compared to liquefied natural gas (LNG), which is normally used.   This is on top of the 15 per cent reductions acheived with LNG over traditional heavy-fuel oil-powered vessels.

During the week, a total of about 2,600 fewer tonnes of greenhouse gas emissions will be generated than normally.  The reduction corresponds to the average annual carbon dioxide footprint for 270 Finns.

Viking Line’s Sustainability Manager, Dani Lindberg notes: “This is an historic moment for us, the Baltic Sea and maritime transport.  Scheduled services have never before been powered solely by biogas.  We have invested 450 million euros in our climate-smart vessels Viking Grace and Viking Glory, and one of their most important features is that they can run on LNG, biofuel and future synthetic fuels produced from renewable energy.  Such significant environmental measures are the result of our long-term work.”

Over the past year, Viking Line has offered its passengers and its conference and cargo customers the option of purchasing biofuel corresponding to the amount of fuel used for their travel.  This reduces emissions by 90 per cent per passenger or cargo unit.

“Both consumers and corporate customers expect responsible conduct from us, and they themselves are prepared to take part in protecting the vulnerable nature of the Baltic Sea’s archipelagos.  The number of trips using biofuel increased 500 per cent immediately when we highlighted the option earlier in our booking system.”

Normally, LNG is used on the Turku route, and this fuel has significantly lower nitrogen oxide emissions than the heavy fuel oil traditionally used on vessels.  Both LNG and LBG generate virtually no harmful sulfur or particle emissions.

The biogas supplied by Gasum, which makes the fuel from food and agricultural waste.  The biogas is produced in Europe, and the origin of each gas consignment is clearly documented.

“We have already operated Viking Grace using biogas on our Turku route, and passengers and cargo customers on Viking Glory and Viking Grace also already have the option to purchase biogas when they book their trip to offset the fuel used for their own travel and thus reduce the emissions for their trip by up to 90 per cent.  Now, for the first time, we are operating for a whole week using only biogas, which is unique.  There is still limited access to renewable fuels, and the price for such fuels is at least twice as high compared to LNG.  It is important to create demand in order for supply to rise and the price to fall,” says Dani Lindberg.

“Gasum is very happy to support Viking Line in opening this historic week-long green corridor on the Baltic Sea.  This is a clear and concrete demonstration that the green transition in maritime transport is possible with tools available already today.  Our job at Gasum is to help our customers get access to cleaner energy and superior services to reduce emissions on land and at sea”, says Gasum’s VP Maritime, Jacob Granqvist.

Viking Line is involved in efforts to develop a green sea corridor between Turku and Stockholm and between Helsinki and Tallinn.  These green corridors are routes where the transport of both cargo and passengers is carbon-neutral.  Emission reductions in maritime transport are regulated in part by the EU’s Fit for 55 programme for a green transition and the EU emissions trading system as well as the International Maritime Organization’s strategy for greenhouse gas emissions.

Viking Line’s has a long history as a leader in environmentally focused corporate action.

1980s

• Viking Line stops using toxic paint for the bottoms of its vessels and starts using divers to clean vessel bottoms.
• Waste recycling begins on board the vessels.
• First land-based power supply is placed in service in Stockholm.  Today a land-based power supply is also used in Helsinki, Mariehamn and Tallinn.

1990s

• The switch to fuel with a low sulfur content reduces sulfur emissions.
• Wastewater on board the vessels is transported ashore for treatment.
• Cold seawater starts being used to cool the air on board the vessels, and the vessels’ ventilation air is heated by recovering energy from flue gases.

2000s

• Viking Line is the first shipping company in the world to use Humid Air Motor technology to reduce nitrogen oxide emissions.  Emissions are reduced by lowering the combustion temperature of the vessel’s engines using seawater.
• Viking Cinderella’s nitrogen oxide emissions are reduced following the installation of catalytic converters on the vessel.
• Recycling of biowaste starts on board Viking XPRS.

2010s

• The new Viking Grace uses 100% sulfur-free liquefied natural gas (LNG) as a fuel.  The climate-smart vessel reduces nitrogen oxide emissions by 85% and greenhouse gas emissions by 15% compared to vessels that run on oil.  With LNG, there are virtually no particle emissions.
• Viking Grace tests a rotor sail, making it the world’s first hybrid vessel to combine wind power with LNG.  The vessel is also equipped with an energy recovery system that converts surplus heat into electricity.

2020s

• The new Viking Glory is placed in service in March 2022.  The vessel’s engines enable optimal fuel utilization and do not produce any sulfur dioxide emissions.
• Thanks to Viking Glory’s Azipod steerable propeller-mounted propulsion system, the vessel is easy to manoeuvre in port, which saves time and fuel.  The shape of the vessel’s hull also reduces the formation of waves as well as fuel consumption.
• Viking Glory is likewise a pioneer in utilizing waste cooling from LNG.  The vessel’s energy recovery system generates up to 40 per cent of the vessel’s hotel department’s electricity.
• Viking Line starts offering passengers and cargo customers on Viking Glory and Viking Grace the option to purchase biogas equivalent to the amount used for their own travel and thus reduce emissions by up to 90 per cent.
• In honour of Baltic Sea Day, Viking Line will run on biofuel for one week on its Turku route.
