Propane is a hydrocarbon that is a gas at atmospheric pressure, although it can be compressed under moderate pressure into a transportable liquid. It is co-produced with oil and gas, either as a product of petroleum refining or natural gas processing. Propane is used for home heating, cooking, water heating, drying crops and as a transportation fuel. 

Approximately 5% of households in Colorado use propane for winter heating, the majority of which are rural. Despite significant propane production in Colorado, the state is vulnerable to shortfalls due to a lack of pipeline and storage infrastructure. The nearest major storage facilities are in Conway, Kansas and Mont Belvieu, Texas. To obtain fuel from these storage facilities, Coloradans rely mainly on trucking.
