Three school districts at various stages of their propane school bus journeys shared their experiences in an STN EXPO panel. “
We’re all on this pathway to zero,” declared Steven Whaley, director of autogas business development for the session sponsor, the Propane Education & Research Council (PERC).
He shared four traits of an alternative fuel adoption successful: it must be cleaner than diesel, be cheaper, perform just as well, and be plentiful in supply. He explained more about the clean, affordable, safe, widely used, American-made fuel that is propane, which costs less per gallon than diesel and does not require the additives for emissions management that diesel buses do.
A propane bus was also found to be 96% cleaner than a clean diesel bus by researchers at the University of West Virginia. If there was one theme repeated throughout the Green Bus Summit it was that infrastructure is key — the first thing to consider before going bus shopping. Whaley reassured attendees that propane infrastructure is straightforward to set up and run. PERC partners also offer a solar- and wind-powered portable propane fueling station that also powers electric charging and off the grid.
Entire Fleet Converted
Kay Cornelius is director of transportation for rural St. Louis County Schools in Minnesota, with a service area of just over 4,000 square miles and where adverse weather conditions occur regularly. She said she was initially against propane but after conducting much research eventually agreed to her first propane bus in 2016 on a trial basis. She shared that she got into propane for the lower total cost of ownership and has seen the numbers stack up favorably, eventually converting her whole fleet.
“Educate yourself. Learn how it works,” she encouraged. She relayed that she networked with nearby districts to lock in a lower price from propane providers.
Partial Adoption
Township High School District 211 is the largest high school district in Illinois. Director of Transportation Diana Mikelski said 61 of her 164 buses are propane. When getting started, she had to explore her options and face pushback from mechanics.
She confirmed that Blue Bird and ROUSH CleanTech provide amazing support. Propane doesn’t blow up like in the movies, she quipped, and fueling is a breeze. Her fuel savings is half a million dollars, plus maintenance costs. She said her drivers now love the propane buses as they run smoothly even in cold weather. The community has even noticed the cleaner smell and improved student health, she said.
“This is so easy,” she underscored. “We’re fully invested in going 100 percent with this.”
Starting Out
Michael McCusker, senior financial analyst for the “remarkably large and underfunded” School District of Philadelphia’s Department of Transportation Services, said that electric and CNG have been ruled out and the district is looking to switch about 10% of its fleet to propane.
“You learn and you make decisions,” he said of the journey ahead of the district. He added that the district is confident that propane buses can handle the narrow streets and hills that school buses must navigate in the city.
