In 2015
the European Commission (EC) announced a project to build the world’s first fully-electric ferry,able to travel more than 20 nautical miles, thanks to what would be the world’s biggest battery – at least, in a maritime setting.
E-Ferry – a four-year, €21.3 million project – is funded by the EC and industry as part of the Horizon 2020 Research and Innovation programme.
“Ellen, as the ferry has been christened, is a fully electric, medium sized car and passenger ferry, run only on power from batteries charged in harbour,” explains project coordinator Trine Heinemann, “It will cross distances of up to 22 nautical miles (38km) between charging.”
Able to carry 31 cars or five trucks, and as many as 198 passengers at capacity, Ellen will sail between Søbyon the island of Ærø, and Fynshav in Denmark, operated bythe Municipality of Aeroe (ÆrøKommune).
At almost 60m long and 13m wide, and with a top speed of between 13k-15.5k, it will cut the travel time of a single trip to 55 minutes, down from the 70 it takes a fuel-powered vessel currently operating on the route.
A significant part of the design specification was to use lightweight materials, ensuring the ferry uses as little power as possible. The use of steel was restricted to just the specially designed hull, with the bridge constructed from aluminium instead. Deck furniture is constructed from recycled paper rather than wood.
Designers also opted to remove the onboard ramps, instead using shoreside ones. The car deck is also positioned on the same level as passenger areas; in total, the ferry weighs 650t.
