Exploratory steps towards a Sustainable Fleet


Exploratory steps towards a Sustainable Fleet in The City of Largo, Florida

I’d like to share a general overview of some of the options for reducing fossil fuel consumption that I chose to look into. Alternative fuel options were one of the ideas I wanted to investigate in terms of how viable it would be to incorporate different fuels into the city’s fuel portfolio to cost-effectively reduce greenhouse gas emissions. From the fuel consumption data, I found that the majority of fuel consumption came from diesel vehicles, so the main focus was finding fuel alternatives for heavy-duty diesel vehicles (biodiesel and compressed natural gas). With regards to compressed natural gas, I was looking to figure out the economics of incorporating a new fuel into the city’s fleet as well as the sustainability of natural gas when compared to diesel. In terms of economics, I needed to consider not only the cost of the cost of the fuel, but the cost of accessing the fuel (since CNG fueling facilities are not nearly as ubiquitous as gas stations), differing capital costs for CNG vehicles, cost of retrofitting the maintenance shop to accommodate CNG vehicles, etc. I found that the only pre-existing CNG fueling station in the area is about 7 miles away from the public works complex, which is the home base for many of the heavy-duty vehicles that would potentially be using CNG. I decided to pay a visit the station so that I could see the CNG fueling infrastructure for myself. With a fueling station already existing nearby, CNG may be able to play an important transitional role in the city’s efforts to operate more sustainably.
