Slide Topic Content Notes

Increasing the Energy Density of  At atmospheric pressure, the

Natural Gas energy content of natural

gas is low

 For transportation use,

natural gas is either

compressed or liquefied to

increase range

Compressing Natural Gas  1 cubic foot is “squeezed”
into 5.6 cubic inches when
compressed to 3,600 psi

 At 3,600 psi, nearly 300x as
much volume fits into the
same size container

Hazards of Natural Gas 1. High Pressure
2. Fire
3. Asphyxiation

NGV Safety Features to Address  High-pressure fuel system
High Pressure  4:1 safety factor
 14,400 psi minimum

burst pressure
