|
 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
