Shuttle Express added two propane autogas-fueled luxury buses to its fleet. The coaches are the nation’s first two Ford F-550 buses built with the ROUSH CleanTech dedicated liquid propane autogas fuel system, according to Shuttle Express. They recently traveled across 10 states from Kansas to Renton, Wash, refueling at publicly-accessible propane autogas stations.
Since 2010, Seattle’s airport shuttle service has added 72 propane autogas-fueled vans to its fleet, with each new van reducing its carbon footprint by 90 percent compared to traditional gas-fueled vehicles, Shuttle Express said. This saved an estimated 1,525 metric tons of CO2 from being released into the environment in 2012. According to the EPA, that much CO2 is equivalent to:
- The annual greenhouse gas emissions from 318 passenger vehicles.
- CO2 emissions from 20 tanker trucks’ worth of gasoline.
- Carbon sequestered by 1,250 acres of U.S. forests annually.
Currently, Shuttle Express uses about 900,000 gallons of fuel and travels about 10 million miles each year in the Puget Sound area. Shuttle Express has served as SeaTac Airport’s official share-ride company since 1987.
