CNG or LNG(Methane)

4500 psi working pressure3600 psi service pressure4 times space of diesel

Nominal 100 psi (232 psi max)-260˚FahrenheitTwice the space required by diesel

Liquid Natural Gas

• Fewer Tanks • Greater fuel density

– Range and space

• Lower weight storage• Lower installation cost on vehicle• Does not rely on pipelines gas• Use a 2:1 ratio  (LNG:diesel)

– Consider engine efficiency 

• Complexity of tanks• Pressure and temperature management of fuel to engine• Maintenance  cost of Cryogenic parts• Use it or lose it• Reliability is challenging

Compressed Natural Gas

• Unlimited hold times‐little or no fuel loss• More mature technology• Gas/Vapor instead of Cryogenic Liquid• Simple fuel tanks and pressure management 

• Cost of compression• Size of storage tanks• Weight of storage tanks

Compressed Natural Gas 4500 psi working pressure 3600 psi service pressure Cylinder types

Type I (all metal) Type II (metal liner, partial wrap) Type III (metal liner, full wrap) Type IV (plastic liner, full wrap)

Tanks rated at gross capacity Don’t confuse water capacity rating

Range factors Otto or diesel cycle engine Gas composition Fast or time fill Can’t use residual low pressure
