Going Green: Norwegian Shipbuilders Turning to Battery Power

By Mikael Holter and Jeremy Hodges (Bloomberg) — Not far from Norway’s North Sea oil rigs, shipbuilders are assembling some of the first ferry boats ever to be powered entirely by batteries. For years, the yard, nestled against the deep-blue sea waters and snow-clad mountains of the country’s deepest fjord, mostly made fuel-guzzling boats for the oil industry. But orders vanished as crude slumped in recent years. Now, like other Norwegian industries, its future prosperity depends on going green.

“If you look at the next five years, this is what we’ll be doing,” said Erlend Hatleberg, a project manager at Havyard Group ASA, which runs the Sognefjord shipyard that’s switched to specializing in boats with battery technology similar to plug-in cars. “We were in a really deep trough. But activity is back.”

While progress in electrifying the world’s excessively polluting shipping fleets is miles behind advances in automobiles, Europe is making initial strides as Paris Climate Accord goals to cut carbon dioxide emissions loom large. Dozens of battery-powered boats that can move through inland waterways in Norway, Belgium and the Netherlands are about to make their first voyages, including some able to run fully automatically without a crew. Nowhere is this push more prevalent than Norway, a country where almost all electricity produced is hydropower, the state oil company is expanding into offshore wind farming and people drive more electric cars, per capita, than any country in the world. Next up, Norway wants two-thirds of all boats carrying both passengers and cars along its jagged and windy Atlantic coastline to be electrified by 2030. Havyard is filling 13 orders for zero-emission ferries received since 2016.

Some initial kinks made the ship lag the two other ferries that travel the same route, frustrating commuters, but it’s since caught up

“I’m very doubtful that the first steam engine was flawless,” said captain Steinar Johnsen, 47. “If you’re always going to wait for something better, you’re never going to do anything.”

In the Netherlands, Port-Liner BV will deploy five, 52-meter container barges powered by 20-foot batteries this year that can cruise for 15 hours, says chief executive officer, Ton van Meegen. He predicts they’ll divert some 23,000 trucks from European roads when they start servicing ports in and around Antwerp, Belgium, and Dutch cities Amsterdam and Rotterdam.

Also in the pipeline:

  • 10 boats capable of running for 35 hours on four, 20-foot-long batteries;
  • They’ll cut 18,000 cubic tonnes of CO2 from the atmosphere;
  • Regulations are also lagging;
  • The IMO hasn’t yet set out rules to govern sailorless ships, even though companies are racing to design them.

Sailorless ships

Port-Liner’s Dutch barges can be fully automated, while a unit of Norwegian technology company Kongsberg Gruppen ASA will have a 79.5-meter, battery-powered, open-top container ship ready by 2020. Rolls-Royce Holdings Plc predicts its first unmanned ocean-going ship will make its first voyage as soon as 2035. Back in Norway, where national and regional governments spend 3 billion kroner ($386 million) a year to operate the 200 ferries serving 130 routes, Hatleberg is counting on orders continuing. Before the electric boat fad, the yard cut more than a quarter of its workforce. On an icy day in late February, some 120 shipwrights were welding, hammering and laying 75,000 meters of cables over the newest ferry, the 67-meter, 2,100 ton MF Husavik, slated for delivery to ferry operator Fjord1 ASA as early as May.

“We finally have work again,” Hatleberg said. “It’s a pretty tough project. But people are enthusiastic, there’s an extreme will to make this happen.”
