Pros Cons Fleet Applications

BEV

   

Lowest operating cost per mile
Very low maintenance costs
Near silent operation
Quick acceleration
Zero tailpipe emissions
Air quality investment (gets cleaner with electricity grid)
Domestic fuel source, energy security
   

Range often limited to <100 miles
Charging infrastructure is still growing
Higher incremental cost (partially offset with tax credits)
Limited medium and heavy duty options
   

Mostly light duty, some medium duty
Great for applications with <80 mile routes
Meter cars, pool vehicles, city officials
High mileage, short daily route
   

PHEV

   

Low operating cost per mile
Lower maintenance costs
Quiet when using electricity
Quick acceleration
Zero tailpipe emissions in electric mode
No range anxiety
Domestic fuel source, energy security
   

Electric range <40 miles
Charging infrastructure is still growing
Higher incremental cost (partially offset with tax credits)
Still operating gasoline
Limited medium and heavy duty options
   

Fits light duty applications that BEVs won’t
Great for city routes in electric range
Any light duty application not requiring 4WD or truck bed
   

CNG

   

Vehicles in all duty sizes and classes
Cheap fuel
Low maintenance, extended engine life
No diesel emissions filters (DEF)
Low emissions (NOx, VOCs, PM, GHG)
Domestic fuel source, energy security
Colorado jobs

   

High initial infrastructure cost
Higher incremental cost (partially offset with tax credits)
Infrastructure is still growing
Requires high consumption for payback
Shorter range than diesel
Maintenance facility upgrades (if fleet wants on-site maintenance)

   

Light, medium, and heavy duty
Applications with high fuel consumption, high mileage can have a quicker payback
Refuse, dump trucks, pickups w/high mileage, transit, buses

   

LNG

   

Lifecycle cost reduction
Cheap fuel
Higher fuel density than CNG, longer range
Low maintenance, extended engine life
No diesel emissions filters (DEF)
Lower emissions (VOCs, PM, GHG, NOx)
Domestic Fuel source, energy security
Colorado jobs

   

Very high infrastructure cost
Heavy Duty primarily
Higher incremental cost (partially offset with tax credits)
Less infrastructure than CNG
Need to drive high mileage to see fuel consumption that delivers payback
Maintenance facility upgrades (if fleet wants on-site maintenance)

   

Distance trucking
Class 8
Viable if infrastructure is built near fleet headquarters
Operating very large fleet
Long daily routes and high fuel consumption can have a quicker payback

   

Propane

   

Vehicles in classes 1-7
Lifecycle cost reduction
Cheap fuel
Low infrastructure cost
Low maintenance, extended engine life
No diesel emissions filters (DEF)
Lower emissions (VOCs, PM, GHG, NOx)
Domestic fuel source, energy security
Colorado jobs
   

Not as many vehicle options as CNG
Propane vehicle infrastructure growing
Lower energy density than CNG
Shorter range than CNG, diesel
Higher incremental cost (partially offset with tax credits)
Often less vehicle storage space

   

Light and medium duty, some heavy duty with high mileage
Low maintenance
Fleets w/ several fueling locations, cheap infrastructure
School buses, taxi fleets, pickups, transit
   

Biodiesel B20, B100

   

Can use B20 in some existing vehicles
No incremental vehicle, infrastructure cost
Lower emissions (everything but NOx)
Domestic fuel source, energy security
   

Blends over B20 can void warranties
Higher blends change with cold weather
Unless B100, still using petroleum diesel
May not see cost savings like other alternative fuels
   

Fleets wanting to reduce emissions, not invest in new vehicles/infrastructure
Any fleet operating petroleum diesel
   

Ethanol E85 (FFV)

   

Many flex fuel vehicle options
Lower emissions
Cellulosic ethanol market is growing
Little or no incremental vehicle cost
Established infrastructure
Domestic fuel source, energy security

   

Must use in flex-fuel vehicle
E85 in US is currently corn-based
Still using roughly 15% gasoline
Lower energy density, shorter range
May not see cost savings like other alternative fuels

   

Fleets wanting to reduce emissions not invest in new vehicles/infrastructure
Light and medium duties
Any fleet operating gasoline
