Natural gas vehicles have been generating buzz among fleets. But that quiets down for some of them upon seeing the investment required, which can run up to a few million dollars for a fueling station and modifying maintenance shops and vehicles.
Here’s the cost to upgrade to biodiesel blends or renewable diesel: $0. No vehicle or fuel infrastructure modifications are needed.
The biggest expense with natural gas is building a new fueling station, which most fleets put in themselves because of the lack of retail options. Here are potential equipment costs for a time-fill CNG station for fleets that fuel overnight at a central location. This does not take into account costs like land, engineering, vehicle and shop modifications or ongoing expenses.
Line necessary to bring gas to station.
Removes moisture from gas prior to compression.
BUFFER STORAGE TANK
Helps keep the compressor from turning off and on and to top off vehicles.
Compresses inlet gas to the pressure necessary for filling a vehicle. Best practice is to have multiple compressors.
Used to run the compressor and auxiliary equipment in the event of a power outage.
Vehicles fill from the post, typically overnight. A medium-sized station needs 10–40 posts. Estimated at $5,500 per post.
Includes expenses associated with laying concrete, trenching, ductwork, plumbing, electrical connection and upgrades, and material shipping.
