What’s Driving Natural Gas?

• Improving operating economics vs. diesel

• Increasing diesel fuel costs driving quick NG payback

• Reduced after-treatment complexities

• Reduced GHG Emissions; 20% Average

• Noise reduction- Ten db reduction vs diesel

• Domestic Fuel/Energy Security

• Renewable Fuel


Natural Gas Basics

COMPRESSED NATURAL GAS•Natural Gas that is compressed – typically to 3,600 psi – for dispensing and storage

•Gas is distributed through natural gas pipeline (the same infrastructure that delivers to homes and businesses currently) to the fuel location

•Gas is compressed at fuel location into CNG for dispensing into the truck

•Dispensing is similar to gasoline or diesel fuel

• The CNG is stored on the vehicle in one or more cylinders

LIQUEFIED NATURAL GAS•Natural Gas that is cryogenically cooled – to ‐260oF – for dispensing and storage

•Gas is processed at LNG production and transported by special truck to the fuel location

• LNG is stored at fuel location in cryogenic tanks and dispensed directly into the truck

•Dispensing requires special safety equipment

• The LNG is stored on the vehicle in cryogenic tanks


Natural Gas Basics

COMPRESSED NATURAL GAS•ADVANTAGES:• Lowest price (compared to diesel & LNG)• Lowest emissions• Extensive infrastructure already exists• “Truck-Friendly” technology

CHALLENGES:• Volume per energy content (requires more storage)• Additional weight and OAL• Range limits approximately 300 miles • Performance of existing stations

LIQUEFIED NATURAL GASADVANTAGES:• Lower price than diesel• Fastest Fill• LNG is lower weight than CNG; allows greater storage and distance (current max of 400 miles)

CHALLENGES:• Infrastructure only exists in Southern California; SLC; and Connecticut, and Houston• Venting; Performance Issues•Higher production and distribution costs • Truck cost for larger engine (15L) • Shop Requirements


Natural Gas Engine Technology

Stoichiometric EGR engine (Example ISL G/ISX12 L)• Uses high EGR rates in combustion

process in place of excess air (Lean Burn).

• End result is an oxygen free exhaust allowing use of a simple 3 way catalyst

• Fuel Neutral- LNG and CNG

Dual Fuel engine (Example Westport GX 15L)• Uses diesel fuel as a pilot injection for

Liquefied Natural Gas• Due to the use of diesel fuel, exhaust

requires emissions control devices (DPF, DOC, SCR)

• ONLY operates on LNG

How Safe is Natural Gas?

• Heavily regulated industry

• 20 year tank life

• TYPE III and IV Tanks, lightest weight

• Methane is lighter than air; will not pool under vehicle

• Drop/crash Testing

• Bonfire testing

• Dynamite testing

• Pistol/rifle testing – armor piercing bullets

• Google “CNG Tank Testing” – Numerous Web Sites and You Tube Videos

• SUMMARY: NATURAL GAS IS AS SAFE, OR SAFER, THAN DIESEL AND GASOLINE


Customer Purchase Process – Natural GasResearch the Business Case

• FUEL – FUEL – FUEL – FUEL – FUEL – FUEL

• Will products work?

• Weight/length differences?

• Funding availability

• Financing

• Warranties

• Insurance

• Driver reactions

• ONCE AGAIN: is Fuel readily available at competitive cost & flow?

NG Fuel Location & Price Resources


Dealer/Customer Shop Requirements

• NFPA 30A Requirements – Vague

• Methane Detection; Heater Relocation; Exhaust Fans; Explosion Proof Lighting

• LNG Requires All; Can Cost $50K per Bay

• CNG for normal repairs requires only explosion proof lighting

• Exception – Major Fuel System Repairs - Same Requirements as LNG

• Normal Safety Procedures – Close Tank Valves

• NGVA Agrees

• Local Fire Marshall has Final Say


Government IncentivesFederal

The NATURAL GAS ACT of 2011 (HR1380)• Fuel Use – 50 Cent/Gal Tax Credit Extension

• Vehicle Purchase - $32K to $64K Tax Credit

• Fueling infrastructure – Up to $100K Tax Credit

• Currently in the HOUSE - Stalled

• SENATE Introduced Similar Bill, S.1863, November 15

• Drops Fuel Use Tax Credit

• Provisions for Funding – Better Chance of Approval


• Superior maneuverability • Excellent visibility – 2500 sq in

windshield• Unparalleled HVAC system• Ease of entry/exit• Lightweight aluminum cab• Telescoping steering column• Body builder friendliness /

SmartPlex Electrical System• Wide selection of options to fit your

vocation
