Summer traffic opened on 1 June. "Right now our full focus is on the green transition, and it is an important milestone for us that this summer we are running more departures on electricity than on diesel," said Carsten Jensen, CEO of Molslinjen, who reiterated the company's target of converting all its routes to electric operation by 2030.

On the Öresund route, three of four ferries now sail on electricity. The Als and Samsø routes are likewise served by fully electric vessels, while on the Fanø route the busiest ferry runs on battery power. The Bornholm and Langeland routes, together with the high-speed craft on the Kattegat, remain diesel-powered.

On the Öresund route, HAMLET, the third of the high-frequency passenger ferries operating between Helsingborg and Helsingør, has recently been converted to electric operation. Only one older freight ferry still runs on diesel, meaning 95 per cent of all departures across the summer months are scheduled to be carried out on green electricity from fossil-free sources such as solar, wind and hydro power.

Three mega-catamarans are currently under construction in Australia. From early 2028 the vessels will pave the way for an electric future in high-speed traffic when they enter service on the Kattegat.

"It is only now that the technology makes it possible to run large catamarans on electricity, and we therefore have the conversion of the Kattegat and Bornholm routes ahead of us. But with the other routes fully or partly electrified, we expect to cut our emissions by many thousand tonnes of CO2 this summer alone," said Carsten Jensen.

Across the three high-season months of June to August, around 5.4 million passengers are expected to travel on a Molslinjen ferry.
