Viking Line is once again changing the future of sea travel. The company has revealed a revolutionary plan to launch a fully electric passenger car ferry that will operate between Helsinki and Tallinn, promising a cleaner and quieter journey across the Baltic Sea.
The new vessel, named Helios, is expected to become the world’s largest fully electric ferry. According to Viking Line, the ferry could begin operations as early as the 2030s, marking a major shift in how we experience maritime transport.
Built with next-generation battery technology, Helios is designed to carry 2,000 passengers over the 80-kilometre route in just over two hours. Its battery capacity is expected to range between 85 and 100 megawatt hours, with fast-charging stations at ports delivering more than 30 MWh to recharge the ship between trips.
What sets Helios apart is its complete absence of a smokestack — a clear signal of zero emissions. At nearly 195 metres in length and 30 metres in width, it will have space for 650 cars and up to 2,000 lane-metres of cargo. Operating at a speed of around 23 knots, this ferry matches today’s efficiency, without the pollution.
Viking Line’s CEO Jan Hanses described the new vessel as a milestone. “Just like sail, steam, and motor ships in their time, Helios marks the beginning of a new era in shipping,” he said. “This is not science fiction. It’s a commitment to real change.”
The company has a long history of pushing boundaries. Viking Grace became the world’s first ferry to run on liquified natural gas and biofuel. Then came Viking Glory, which cut fuel consumption by up to 10 percent. Helios will go even further by removing emissions altogether.
To support the project, Viking Line has applied for funding from the EU Innovation Fund, one of the largest programs in the world supporting low-carbon technologies. In 2023, Viking Line was Finland’s leading recipient of public corporate funding, receiving over €20 million.
This isn’t just a new ferry. It’s a major leap for sustainability in shipping — and Viking Line is steering it forward.
