• First electric autonomous cargo ship launched in Norway

  The ‘Yara Birkeland’ has a capacity of 6.8MWh sourced from renewable hydroelectricity — the equivalent of 100 Teslas — and would eradicate the need for about 40,000 truck journeys per year

  Zero emissions and, soon, zero crew: The world’s first fully electric autonomous cargo vessel was unveiled in Norway, a small but promising step toward reducing the maritime industry’s climate footprint.

  By shipping up to 120 containers of fertilizer from a plant in the southeastern town of Porsgrunn to Brevik’s port 12km away, the much-delayed Yara Birkeland, shown off to the media on Friday, would eliminate the need for about 40,000 truck journeys a year that are now fueled by polluting diesel.

  “Of course, there have been difficulties and setbacks, but then it feels even more rewarding to stand here today in front this ship and see that we were able to do it,” said Svein Tore Holsether, chief executive of Norwegian fertilizer giant Yara International ASA, with the sleek blue-and-white vessel moored behind him in an Oslo dock, where it had been sailed for the event.

  The 80m, 3,200 deadweight tonne ship is soon to begin two years of working trials, during which it would be fine-tuned to learn to maneuver on its own.

  The wheelhouse could disappear altogether in “three, four or five years,” said Holsether, once the vessel makes its 7.5 nautical mile (13.89km) trips on its own with the aid of sensors.

  “Quite a lot of the incidents happening on vessels are due to human error, because of fatigue for instance,” Yara International project manager Jostein Braaten said.

  “Autonomous operating can enable a safe journey,” he added.

  While the distance the Yara Birkeland would cover might be short, there would be many obstacles.

  It would have to navigate in a narrow fjord, and sail under two bridges while managing currents and heavy traffic from merchant ships, pleasure craft and kayaks, before docking at one of Norway’s busiest ports.

  The next few months are to be a learning period.

  “First of all, we have to detect that there’s something there. We have to understand that it’s a kayak, then we have to determine what to do with that,” Braaten said.

  “Currently, large vessels don’t do much with a kayak. They can’t do much. They can warn, but they cannot maneuver away” or reverse to avoid an incident, he said.

  Autonomous navigation woud require a new set of regulations that do not exist yet.

  On the Yara Birkeland, the traditional machine room has been replaced by eight battery compartments, giving the vessel a capacity of 6.8 megawatt hours (MWh) — sourced from renewable hydroelectricity.

  “That’s the equivalent of 100 Teslas,” Braaten said.

  The maritime sector, which is responsible for almost three percent of all man-made emissions, aims to reduce its emissions by 40 percent by 2030 and 50 percent by 2050.

  Despite that, the sector has seen a rise in the past few years.

  International and domestic shipping and fishing combined, the industry emitted more than 1 billion tonnes of greenhouse gases in 2018, up from 962 million tonnes in 2012, International Maritime Organization figures showed.

  By itself, the Yara Birkeland’s contribution to global climate efforts would be just a drop in the ocean — eliminating 678 tonnes of carbon dioxide per year churned out by the redundant trucks.

  Experts also do not expect electric vessels to become a universal solution for the industry any time soon.

  “Electricity has a ‘niche’ use, in particular for ferries as these are often short and stable routes, possibly on coastal and river transports, but it’s not well-adapted for long ocean crossings,” said Camille Egloff, a maritime transport expert at Boston Consulting Group.

  “Not only would [a vessel] need to be autonomous for long distances, but you would also have to equip ports with battery chargers, so there are technical and infrastructure challenges that would need to be coordinated,” she said.

  While dozens of electric ferries already criss-cross the fjords of Norway — a major oil and gas producer which is paradoxically also a leader in electric transport — ocean liners would have to rely on other technologies to go green, such as liquified natural gas, e-methanol and hydrogen.
