Dive Brief:

• The city of Fargo, ND, is considering using excess gas in municipal vehicles from a landfill that currently captures methane on site and produces heat and electricity. 
• City officials want to convert some of its fleet to compressed natural gas (CNG).
• Fuel for city vehicles, including sanitation trucks, police cars, and busses, is one of Fargo’s greatest expenses.

Dive Insight:

The plan, if approved, is expected to save the city money. However, the cost of acquiring new vehicles, adding fueling stations, and implementing modifications to the current facility will increase the project's cost.  

Another possible pitfall: Landfill-gas emissions can vary each day, so natural gas would have to be purchased and kept on hand as a backup.
