Natural Gas Busses are a Better Option, Study Finds

October 28, 2013


A study for the Grater Lafayette Public Transportation Corp. found that the bus system could reduce its cost and emit significantly fewer pollutants by converting its fleets to natural gas.


Purdue University energy economist Wally Tyner reports that the approach of fueling buses with compressed natural gas, or CNG, could apply to similar municipal bus systems nationwide.


“Because of the lower fuel price and pollution reduction, the CNG bus is considered to have good potential as an alternative vehicle used in the public fleet in the United States.”


The objective of the study was to analyze the transportation system in Lafayette, called CityBus. The study set out to find the most effective way to reduce operating costs and make the fleet greener. Currently the bus fleets run on standard diesel. The report concludes that buses fueled by natural gas would be the lowest-cost option for CityBus.


Natural gas production in the U.S. has increased dramatically in recent years, and is expected to increase until 2035.
