B. Fueling Station Basics

C. Fueling Basics

D. Safety Hazards

E. “Typical” Applications

33

Propane Autogas 101

oLPG or Propane or Autogas has the chemical formula C3H8

oIt is transferred into a vehicle as pressurized liquid and will vaporize at atmospheric pressure and ambient temperature.

oLike gasoline or diesel, propane gas is heavier than air.

oPropane is burned in internal combustion engine to power vehicle.

oPropane is dispensed and sold by liquid gallon.

44

Propane Fueling Basics

oService pressure of a propane system is at least 240 psi. At this pressure the LPG will stay a liquid at temperatures of 120° F or less.

oBy code, LPG fuel tanks are only allowed to be filled to roughly 80% of volume.

oPropane Autogas station is similar to gasoline station.

oFueling time is similar to gasoline station; about 10 -12 gallons per minute.

55

Propane Station Basics

66

Propane Safety Hazards

oSimilar to gasoline, Propane is a flammable fuel and ignition sources are forbidden in fueling areas.

oPropane is stored and pumped into vehicles in pressurized liquid state. Hazards of pressure exist.

oOperators can be freeze burned from contact with liquid propane.

oPropane is an asphyxiating gas which will displace oxygen if trapped in enclosure.

77

CNG 101

oCompressed Natural Gas (CNG) is predominately Methane (chemical formula CH4).

oNatural Gas typically exists in a gaseous vapor form.

oUnlike gasoline, diesel, or propane; natural gas is lighter than air.

oCNG is burned in internal combustion engine to power vehicle.

o5.66 lbs (~125 SCF) of natural gas is a Gasoline Gallon Equivalent (GGE)

88

CNG Fueling Basics

oNominal pressure of CNG storage in U.S. is 3600

psi. Older 3000 psi systems are mostly phased out.

oCNG pressure is 3600 psi at 70° F (settled

pressure), and no more than 4500 psi at any temp.

oFueling is typically done as a “fast-fill”; about 5-10

“gallons” per minute. “Time-fill” for overnight fueling

can take 4-10 hours.

o“Fast-fill” station is similar to gasoline station.

oHome fueling can be done in residential garage.

CNG Station Basics

1010

CNG Safety Hazards

o Similar to gasoline, CNG is a flammable fuel and

ignition sources are forbidden in fueling areas.

oCNG is stored at high pressure. High pressure gas

is an energy hazard and poses risk to operators.

oNatural gas is an asphyxiating gas which will

displace oxygen if trapped in enclosure.

1111

Electricity as Trans. Fuel 101

oAC power is delivered to the electric vehicle supply

equipment (EVSE) (often referred to as a charging

station) and is typically converted to DC power in

the vehicle.

oDC power is stored in a battery to drive the

vehicle’s electric motor.

oElectricity is sold per kWh. It can be sold in many

different ways commercially as a vehicle fuel (e.g.

subscription, per hour, per charge, per kWh, etc.).

1212

EV Charging Basics

oFueling can be performed in a residential garage or

at commercial location:

o Level 1 - Standard household 120 VAC, 12 A, 7 to 16 hours for full charge.

o Level 2 - 240 VAC, 20 A, 3 to 7 hours for full charge.

oDC Fast Charge - requires 480 VAC to charger, DC

current goes directly to battery, charges vehicle to

80% capacity in 30 minutes.

1313

EV Station Basics

1414

EV Safety Hazards

o Electricity poses an energy potential, fire, and

shock hazard to operators.

oHigher voltage and current can pose increased

risks.

1515

Best Practice and Application

o All of these alt fuels are a triple win:

o Economic advantages

o Environmental benefits

o Energy security benefits

o All of these alt fuels offer “dedicated” and “bi-fuel”

options; option to use traditional fuel and/or alt fuel

o Idle reduction and driver training are first steps

towards greening your fleet

o Training is key to every safe deployment

1616

Best Practice and Application

oGetting “buy-in” from the whole organization (drivers,

maintenance personnel, management) is key to

every successful deployment

o Knowing vehicle needs and driving characteristics is

critical in selecting the correct alternative fuel(s)

o If you don’t know your fleets characteristics, let the

National Renewable Energy Lab help through the

Fleet DNA Program.
