A Halifax councillor wants the municipality to look into using hydrogen energy to power transit buses and ferries.

Richard Zurawski called for a report on hydrogen fuel cells at the December meeting of the city's environment committee. His motion was approved.

"I think this is a perfect time for us to start looking at how we can facilitate something that will sustain us for decades to come in a way that will not trash the environment," said Zurawski.

Hydrogen fuel cells convert energy into electricity and run vehicles on a battery system similar to that of electric cars, which use lithium batteries. Hydrogen energy produces water ? not carbon ? when burned.
