Halifax Transit exploring alternative fuels for bus fleet

Natural gas, battery-electric, hydrogen fuel cell and hybrid-electric are among the options under consideration.

As the municipality seeks to meet its greenhouse gas reduction targets, Halifax Transit is exploring fuel alternatives to diesel to power its bus fleet.

The Halifax Regional Municipality issued a tender on Wednesday for reports that will outline options, including the cost, driving range and estimated greenhouse gas emissions for each technology.

The reports will include "all available bus technologies," but the tender specifically requests information about powering vehicles with:

  • Compressed natural gas.
  • Renewable natural gas.
  • Diesel gas.
  • Battery-electric.
  • Liquified natural gas.
  • Hydrogen-fuel cell.
  • Hybrid-electric diesel.
  • Converted diesel to electric.
  • Converted hybrid to electric.

Right now, 338 of Halifax's buses run on diesel and two are hybrid diesels.

Greenhouse gas target

Halifax has set a goal of reducing greenhouse gas emissions to 30 per cent below 2008 levels by 2020, but that target only encompasses energy consumption for buildings, street lights and fleet vehicles not including Halifax Transit buses.

The document notes the municipality has made progress on that goal, but as the region "experiences particularly severe climate risks such as sea level rise, increasingly intense hurricanes, storm surges and coastal erosion, there is a need to accelerate the progress."

As of the end of the 2015-16 fiscal year, Halifax was about a quarter of the way to its target. More recent numbers have not yet been finalized, said a municipal spokesperson.

According to the tender, "tremendous opportunity exists to reduce HRM's GHGs [greenhouse gases] by focusing on Halifax Transit's conventional bus fleet."

The final report, due at the end of February, will contain recommendations on which technologies the municipality should adopt and how those technologies should be implemented.

The report must also address the impact of the fuel sources on worker health and safety, and the reduction in waste and toxicity.
