|
Space-efficient infrastructure; storage can be located outside facility with dispensers located indoors or outdoors
|
Moderate maintenance requirements
|
None, though refueling system may have requirements
|
Simple, fast refueling
|
Consistent power delivery until full depletion
|
LITHIUM-ION BATTERIES |
No harmful emissions
|
No specialized changing or maintenance rooms required
|
No maintenance or equalization required
|
More intense electrical grid burden, depending on fleet size and charge intervals.
|
Designed for opportunity charging; faster recharge capability than lead acid

Consistent power delivery until full depletion
|
Thin Plate Pure Lead (TPPL) |
No harmful emissions
|
No specialized changing or maintenance areas required
|
No maintenance required, fast equalization
|
Moderate electrical requirements, depending on fleet size
|
Designed for opportunity charging, faster recharge than traditional lead acid
|
Slight power output decline as charge depletes
|
LEAD ACID BATTERIES |
None while in operation, but does emit fumes that require ventilation during battery charging
|
Separate room, infrastructure often required for battery charging, changing and maintenance
|
Higher maintenance requirements compared to other electric options
|
Moderate electrical requirements, depending on fleet size
|
Complex and time-consuming battery maintenance, charging or changing
|
Diminishing power output as battery charge depletes
|
INTERNAL COMBUSTION ENGINE |
Emissions while in operation. Well-suited for outdoor or properly ventilated environments
|
Primary fueling and storage infrastructure located outside facility
|
Requires regular, but not daily, maintenance
|
None
|
Simple, fast refueling with tank changes or pump
|
Consistent power delivery until full depletion
