In one week, Whistler’s fleet of hydrogen fuel cell buses will be parked as their five-year pilot project ends. Nova Bus diesel buses will be replacing them as of April 1st, 2014.
The fleet of twenty buses is currently the largest fleet of hydrogen fuel cell buses operating in the world. The fuelling station for the fleet is also the world’s largest hydrogen filling station.
The hydrogen fuel cell buses were brought to Whistler by a five-year demonstration project sponsored by the federal, provincial and municipal governments, and the Canadian Hydrogen and Fuel Cell Association. The buses arrived in late 2009 and the fleet commenced full operation in time for the 2010 Winter Olympics.
The hydrogen fuel cell is a green technology as the only by-product is water. That means there are no harmful fumes emitted from the bus! In addition, the efficiency of the fuel cell is about 60-70%, which is significantly higher than the average diesel engine at 30-40%.
One of the difficulties for the project was getting the hydrogen fuel from a green source. Up to this day, hydrogen is trucked in from a supplier based in Quebec. Although it is possible to produce the hydrogen fuel closer to home, using non-renewable resources to perform the electrolysis would negate the environmental friendliness of using the hydrogen fuel cell in the first place.
The hydrogen fuel cell demonstration project is deemed a success. The technology is still at its infancy so there’s high hope for it in the future. Although the hydrogen buses were environmentally friendly, the overall operating cost per kilometre far exceeded those of diesel or CNG buses. As the technology matures and the hydrogen infrastructure expands, hopefully the operating costs will decrease to something comparable to diesel or CNG.
For the twenty buses in Whistler though, let’s hope to see them repowered with a different engine (compressed natural gas maybe?) so that they don’t need to see the scrap heap so soon.
