Cryogenic Liquid -260¼
F (-162¼ C)
Yes, LNG is cold; but vacuum-jacketed piping and dispensing components
keep the cold inside, and not outside the pipes and dispensers. |
98% Methane
In the process of liquefaction, most natural gas impurities are filtered
out. LNG is the feedstock that produces the highest quality natural gas
for vehicle engines. |
Lighter Than Air
Unlike diesel or propane, fumes don’t linger at ground level where
they might contaminate ground water. Instead, they quickly dissipate. |
Low Pressure
LNG is stored at pressures of 50 PSI (3.5 bar) to 150 PSI (10.3 bar) versus
a pressure of 3,000 PSI (206.8 bar) to 3,600 PSI (248.2 bar) for CNG.
Reduced pressure lessens the chance for a leak, and reduces the consequence
of a leak if it should occur. |
High Ignition Temperature
999° F versus 480° F for diesel |
Small Flammability Range
5% to 15% of atmosphere versus 1% to 99% for gasoline |
High-Energy Density
3.5 times the density of CNG. The benefit is you need a lot less on-board
storage for LNG than you do for CNG. |
