Southern Hemisphere’s first fully electric passenger ferry launches in New Zealand 09:00

East by West Ferries service has officially launched the Ika Rere zero-emission vessel in Wellington, New Zealand.

Research by the New Zealand Government has found that domestic ships such as ferries and freighters emit close to 300,000 tons of CO2 every year.

In Wellington, nearly 50 per cent of the city’s emissions were produced from the transportation sector in 2020.

With the local council committing to becoming a net-zero-carbon city by 2050, introducing alternative energy forms of transportation is crucial.

The 19m Ika Rere ferry can carry up to 132 passengers on journeys across Wellington Harbour at an operational speed of 20 knots.

It has been designed and built to complete one return run of 25km before charging dockside at a rate of one megawatt for 15 minutes while passengers disembark and board.

The ferry will be charged from a 300-kilowatt charger at its overnight berth during its first year of operation.

It is anticipated that the Ika Rere ferry will save approximately 640 tons of CO2 annually compared to a similar-sized diesel alternative.

New Zealand electrical company McKay acted as the project’s lead electrical designer and system integrator, choosing one of Danfoss’ Editron drivetrain systems to power the ferry.

The system consists of two propulsion motors, two grid solutions for the AC network and six DC/DC converters connected to the vessel’s batteries.

All of these components operate via a DC cabinet and are controlled via an electronic control system.

Erno Tenhunen, marine director of Danfoss’ Editron division, said:

“As companies, cities and countries around the world continue to set CO2 reduction targets, the demand for zero-emission vessels and machines continues to grow. Our Editron marine system provides outstanding efficiencies within a power range of up to six megawatts. It is also compact and lightweight, enabling space and weight savings and increasing design freedom. These savings ultimately benefit passengers, as operators can provide a greater level of comfort.”
