Propane, also known as liquefied petroleum gas (LPG) or Autogas, is stored as a liquid and propane fueling infrastructure is widespread. The Commonwealth of Kentucky collaborates with the Kentucky and National Chapters of the Propane and Education Research Council (PERC) and the Kentucky Propane Gas Association for new technology applications.

Propane Projects in Kentucky

Mammoth Cave National Park

Mammoth Cave, KY

Mammoth Cave National Park (MCNP) installed propane (LPG) refueling in 2012.

The partnership with Clean Cities replaced four aging propane buses (three 1990 models and a 1977 model) with new ones, and also two gasoline pickup trucks with two propane pickups.  The propane buses are used for transporting some 400,000 park visitors from parking lots to cave entrances annually. The park plans to use propane for some park equipment, including a water heater, portable generators, and mowers.  Mammoth Cave National Park sits on more than 52, 000 acres in southwestern Kentucky and has 80+ employees. This was the first 100% alternatively fueled national park in the country of 385 national parks in all.

First propane powered school bus

Crittenden County, KY

In July 2013 Crittenden County Schools, located in Marion, KY put into operation Kentucky’s first LPG powered school bus transporting students. This is the first school bus in Kentucky to be powered by a fuel other than gasoline or diesel. Crittenden County’s propane school bus is cleaner burning, safe, saves in fuel costs, and is a model for other school districts to follow. With propane costing about half as much per mile as diesel fuel, Crittenden County is expecting to save over $5,000 per year in fuel costs per bus.  Crittenden is adding two additional buses in the spring of 2014, for a total of three propane school buses.

Crittenden County has received additional funding from The Kentucky Division of Air Quality to reduce diesel emissions from its school bus fleet. The project will replace four older model diesel school buses with four new school buses powered by propane auto gas.
