The Canadian Urban Transit Research & Innovation Consortium (CUTRIC) has partnered with Enbridge Gas to launch three studies comparing buses powered with renewable natural gas (RNG), compressed natural gas (CNG) and diesel fuel. Conducted separately for Calgary Transit, Orange County Transportation Authority and TransLink, these four-month projects analyze factors ranging from fuel usage and vehicle maintenance to the total cost of ownership and greenhouse gas emissions based on differing propulsion fuels in transit buses. Each project delivers a comprehensive review of existing CNG and RNG applications across Canadian and U.S. transit fleets, and determines total emissions based on transit fleet data from selected samples and average values. With roughly 825 CNG buses on Canadian roads, and with Canada's operating RNG production facilities soon to be joined by more, the technology can help displace diesel, one of the most carbon-intensive and costly fuels in the marketplace. |
