Question for fleet owners and operators: Would you rather operate your fleet burning a fuel whose price per gallon you can accurately predict or one that has massive volatility and whose price is subject to the self-interest of foreign nations?
This is one of the main distinction when comparing CNG and Diesel. Don’t take our word for it, check out the prices recorded by the Dept. of Energy’s Alternative Fuels Data Center over the past decade.
CNG’s price (in blue) remains flat thanks to domestic natural gas production while, conversely, Diesel and Propane (in black & red) spike up and down making both very hard to reliably predict.
With CNG, a fleet can “know” its fuel costs and sign long term fueling contracts with assurance that the price will be consistent. With Diesel and Propane…not so much…
