Lithium battery-powered ships tackle pollution on West Coast

A Vancouver-based business that worksto reduce pollution produced by the shipping industry around the world is bringing the benefits back toCanada.But is that enough to get the industry to use clean energy?

"We're very pleased to have our product deployed locally for the first time," saidAndrewMorden, the CEO ofCorvusEnergy, whichproducesfull and hybrid lithium ion battery systems that power large and small vessels.

"We've done the same thing [for ships] that Tesla's done forcars,"saidMorden.

The company'sbatteries are currently being used in 35 ships across Northern Europe, and it recently received aninvestment fromStatoil,Norway's largest offshore oil company.

Soon, the batteries will also be used in vessels on Canada's West Coast.SeaSpanhas signed off for two hybrid cargo ferries, andMordensaid BC Ferries is also considering using the technology.

Mordensaid one of the company's hybrid systems results in a20 per cent reduction in carbon emissions.

That'sparticularly encouraging, he says, given that most large vessels are powered by diesel fuel, which produces more fine particulate matter than gasoline.

"In the shipping industry there's certainlybeen a focus on reducingemissions, becauseon a globalscale it really does matter," saidMorden.

More incentives needed for change

Robert L. Evans, author of Fueling Our Future: an Introduction to Sustainable Energy, agrees that lithium batteries are a much cleanerenergy source.

But he says just creating cleanertechnology isn't enough to get industries to start using it.

"The issue is the very high energy density and relatively low cost of fossil fuels," said Evans.

"If you don't have a price on carbon, that's where people will go.Thereneeds some sort of incentive to move to something else."

Evans says there are only three sources of power in the world: fossil fuels, renewable energy, and nuclear. Currently, 80 per cent of the world's power comes from fossil fuels, he says.

Diesel engines in particular are20 to 30 per cent more efficient than gasoline, says Evans,which is why they'reso often used for heavy duty industrial purposes.

But he points to the car industry to show how lithium batteries could gain traction.

He says although cars like Tesla are too expensive for the average consumer, others like theChevrolet Volt have started to use hybrid technology to offer consumers a more affordable and sustainable ride.

Evans also calls attention to B.C.'s carbon tax, which he says has been effective in reducing emissions.

"If you send a strong enough price signal to industry, they will start looking for other alternatives," he said.
