Ottawa eyes biofuels for navy fleet

The federal government is soliciting proposals for how it might use biofuels to replace traditional diesel

OTTAWA—Before Ottawa goes full steam ahead with an idea to power navy ships with biofuels, it wants to know if the cost of doing so will sink the plan.

The federal government is soliciting proposals for how it might use biofuels to replace traditional diesel—assuming the price is right.

“Naval vessels and platforms have traditionally operated by the use of fossil fuels to power many of their systems. Biofuels are environmentally much cleaner than fossil fuels, producing less air pollution and consuming some materials that would otherwise be considered garbage,” says a notice posted Monday.

“Simply converting fossil fuel powered systems to biofuel-powered systems can be complicated and may become costly from the perspectives of financial, space and maintenance requirements, for example.

“In order to determine if the costs incurred can be justified, the benefits or efficiencies gained must also be determined.”

Those efficiencies include kilometres and dollars per litre, the amount of time and people needed to maintain the system, space and storage requirements and whether biofuels reduce emissions and generate much waste.

A similarly worded notice was posted in late 2011, but it’s not clear if a previous biofuels report was ever commissioned. A spokesman for the Royal Canadian Navy did not immediately return calls Monday.

The biofuels idea is not uniquely Canadian. In 2009, the U.S. Navy announced its “Great Green Fleet” initiative, which aims to fuel an entire aircraft carrier strike group with alternative sources of energy—including nuclear power—by 2016.

Energy-security concerns—the U.S. Department of Defence is among the world’s largest users of oil, much of it foreign—prompted the Great Green Fleet initiative.

The U.S. Navy deployed ships and aircraft running on a 50-50 mix of old-school fuel and biofuels made from used cooking oil and algae off the coast of Hawaii last year as part of a major naval exercise.
