Electric propulsion lets Norway ferry passengers hear the sounds of the fjords

Whisper-quiet electric and hybrid propulsion systems from Siemens Energy can cut vessel fuel consumption, emissions, and costs up to 90 percent 

Reducing maritime emissions to fight climate change

When passengers on the Bastø Electric, the world’s largest all-electric car ferry, cross the Oslo Fjord, they can enjoy the mountain views, salt air, and sounds of waves and gulls in relative quiet.  The noise, fumes, and vibration of traditional diesel engines are gone. 

Climate change demands urgent action. And these technologies can revolutionize the maritime sector, which generates three percent of global greenhouse gas (GHG) emissions. In fact, 81 percent of the world's 91,000 ships are small or medium-size vessels with decades-old, fossil-fueled propulsion systems. Fortunately, with today's advanced propulsion technologies, their operators can convert them to electric or hybrid electric to save fuel, maintenance, and GHG emissions.


Of course, in maritime propulsion applications, no one size fits all. That is why we offer tailor-made electric and hybrid systems for vessels of all kinds. Battery hybrid solutions, for example, can save up to 90 percent in fuel consumption, emissions, and costs. All with less noise — not only in Norway’s fjords but around the world.

"Maybe it's a small piece we can do, but what we see ist that people have passion for this and if everyone does a little - this can make a big impact on the world."

Potential on reducing ferry emissions by electrification


Decarbonizing marine transport

A study on the electrification of the European Ferry Fleet 

A study conducted by Siemens Energy and the non-profit environmental organization Bellona shows that Europe can reduce CO₂ emissions in key countries by nearly 50 percent. This would save 800.000 tons of CO₂ each year, thanks to already available technologies.  

Norway’s “ferrytale” on green waves

World's largest all-electric car ferry

Bastø Fosen’s investments in electrification of their fleet – with large battery packs and lightning-fast charging systems – means  that the company will reduce its CO2 emissions by 75 percent in 2022 – reducing their diesel consumption by six million liters per year.
