Why Natural Gas For Vocational Trucks?

Less Expensive Than Diesel– Today you can save $1.00 to $1.50 per

gallon compared to diesel.– No DEF Fluid Needed– EIA projects low cost NG out to 2035

due to increased US production. Works - Proven Technology

– The Cummins Westport engine is a dedicated natural gas engine with over 30,000 units produced.

– No Need for DPF or SCR systems Domestic

– 98% Domestically Produced– Price not Influenced by Global Politics– 120+ Years of Domestic Reserves

Cleaner and Quieter– Reduces green house gas emissions by

23% compared to diesel– Significant noise reductions – 90%

quieter– Replacing one diesel truck with one

that operates on natural gas has the same emissions benefits as taking 325 cars off the road per year

Station Design/Cost Considerations

Do you have gas on site? What is the inlet pressure? Do you have 3 phase power? Inlet pressure factors into compression

Stations are sized based on the number of vehicles, gallons used per day & fueling window

Standard Cubic Feet per Minute (SCFM) = throughput The higher the SCFM the more compression

equipment/money (Redundancy Vs. Single Compressor) Fast-fill station = can fill vehicles in rapid succession Time-fill station = fuel window between 6-12 hours by

design

Natural Gas Cost Less Than Diesel

Natural Gas Averages $1.00 to $2.00 a gallon equivalent less than diesel

Savings on Fuel Can Allow for a Quick Payback for the Additional Equipment Cost associated with CNG Vehicles.

Typical Fuel usage is 40 DGE’s per day or 10,000 DGE’s per year (250 Working Days) 7 Year Average Equipment Life CNG Incremental Equipment Cost is Between $30,000 and $40,000

Fuel Savings per DGE: $1.00 $1.25 $1.50 $1.75 $2.00

Savings per Year: $10,000 $12,500 $15,000 $17,500$20,000

Total Savings over 7 Years: $70,000 $87,500 $105,000$122,500 $140,000

Building Modifications & Code Requirements

NFPA 30A: Code for Motor Fuel Dispensing Facilities and Repair Garages

Ventilation requirements:– Exhaust duct openings shall be located so they effectively

remove vapor accumulations at floor level from all parts of the floor area

– Repair garage’s forced air heating, air-conditioning & ventilation systems shall not be connected to any other systems in the building

Heat producing appliances requirements:– No open flame heaters or heating equipment with exposed

surfaces producing a temperature in excess of 750 degrees Fahrenheit

• Appliances need to meet NFPA 90A, NFPA 31, NFPA 211 & NFPA 82

Non-explosive lighting needs to be installed if lights are within 18 inches of the ceiling

Next Steps

NG Trucks are the Best Transportation Solution long-term– Lower operating costs, sustainable & growing price

differential If NG Trucks are opportunity for your fleet,

then “Scope the Opportunity” with us– We will analyze your Company’s Transportation Data

• Where does your Fleet travel most?• What is the monthly fuel consumption?

Identify specific “Corridors” that have sufficient fuel use and overlap with America’s Natural Gas Highway

If private NG station is desired, Clean Energy will build, operate and maintain the facilities over a long-term contract– With Customer or Clean Energy capital

Conclusions

The benefits of natural gas for vehicles is that it is CLEANER, CHEAPER, and Domestic

Natural gas refuse trucks can reduce GHG by over 23% vs. diesel

Cities and private companies are making the transition to natural gas vehicles due to economic and environmental reasons

Public policy is driving further interest in natural gas for low carbon and domestic energy security reasons

Excellent examples exist across the US for municipalities and private companies to emulate
