Knight’s Airport Limousine Service, Inc., of Shrewsbury, Mass., unveiled its newest fleet Ford E-350 vans powered by propane autogas. The eight alternative fueled vehicles will service Logan International, T.F. Green, and all New England and New York airports, as well as provide ground transportation for private events.

The fleet of ROUSH CleanTech Ford E-350 passenger vans will also emit 1.15 million fewer pounds of carbon dioxide emissions over the lifetime of the vehicles, according to the company.

Knight’s Airport Limousine Service, ROUSH CleanTech, the Propane Education & Research Council, and the New England Propane Gas Association worked with Senator Michael O. Moore in order to change the Massachusetts State Regulations to allow alternative-fuel vehicles to travel through its tunnels. Due to the recent change, Knight’s elected to move forward with “greening” its fleet, according to the company.  

For its refueling infrastructure, Knight’s Airport Limousine Service installed an above-ground 18,000-gallon tank at its Shrewsbury, Mass., facility. The infrastructure for propane autogas is less expensive than any other alternative fuel, and with thousands of stations across the nation, propane autogas already has the largest public refueling infrastructure of all alternative transportation fuel options.
