B.C. company develops battery for Swedish 'hybrid' ferry

A B.C. energy-storage company will showcase the power of its lithium battery on international waters next year.

Richmond's Corvus Energy has beenselectedby the Sweden-based ferry operator StenaLineto provide electric power for its first hybrid-style vessel, on a 3-hour route between Sweden and Denmark.

The technologywill work much like that of a plug-in hybrid vehicle, saidSeanPuchalski, vice-president of strategic marketing and accounts forCorvusEnergy.

"A lot of people are familiar with electric vehicles. whether they be hybrid or plug-in hybrid, or fully battery electric. So, this is an extension of that,"Puchalskisaid.

"Your fuel bill is less and your impact on the environment is less," he said.

According to Puchalski, StenaLine will be the first Swedish ferry operator to runa ferry with zero emissions while berthingand in port.

The long-term plan is to run the passenger ferry purely onbattery power.

Prices, environmental footprint will decrease

Puchalski said it follows a trend toward electric poweracross the world, in an effort to cut down fuel costs.

He said the environmental footprint of the shipping industry will drop significantly when more marine companies choose to plug in and use a battery instead of relying onfossil fuels.

The battery system for the ferry costs roughly $25 million, according to Puchalski. While powering such large vessels with a batteryis an expensive measure right now, the cost will drop as more companies adopt them, hesaid.

"There is an incremental cost increase over traditional technology. That increment is coming down as more and more batteries are used," he said.

B.C. hybrid projects

Puchalski said he'd now like to see more partnership with Canadian companies.

Corvushas already built a partnership with BC Ferries, which will see a battery-operated ferry hit the open water on some small-vessel routeseither at the end of this year or the beginning of next.

"We have some initial projects in Canada with the Seaspan ferries and later this year with BCFerries," he said.

He said Corvus will also be working on two of the smaller hybrid-style ferries on B.C.`s North Coast
