The sea way is the low emission highway
Maritime transport pollutes less and is more energy efficient than any other mode of transportation. The Port of Oslo aims to transport more cargo and passengers by sea. Each year nearly 1.3 million passengers travel with DFDS and Stena Line to Denmark. The ships also carry large quantities of goods.
This is shore power
From the power station at Vippetangen, electric power goes to the ferries' electrical systems. The ferries connect seamlessly to the grid with the help of a cable crane. The crane is equipped with an 11 kV high voltage cable. Diesel powered auxiliary engines onboard can be shut down while the ferries are powered by clean electricity. The power requirement of the ferries is about 2-3 MW. That's almost 60 times more power than today's fast chargers for electric cars. Shore power saves the ferries about 1,420 tons of fuel annually.
When the ferries are connected to shore power, they annually use between 5 000 000 – 6 000 000 kWh. This corresponds to the annual power consumption of almost 400 Norwegian homes. The shore power station has a cost of aprox 17 Million Nkr.
The Port of Oslo
The port aims to reduce 85 % of the CO2 emission by 2030 (action plan adopted by City Council in Nov 14th 2018). Also read (in Norwegian) Vil bli nullutslipp containerhavn. Moving cargo from road to sea transport reduces at least 50 % of both air pollution and carbon emissions. The port is promoting alternative fuels and new technology, building infrastructure for emission free solutions, and building shore power for ships.
