▪ Requires Personal Protective Equipment (PPE)

Purpose of LNG ▪ Provide onsite storage of LNG
Fueling Station ▪ Warm LNG in the storage tank
Equipment ▪ Increase pressure for delivery
▪ Measure and dispense LNG

Public Access LNG ▪ Stations like this dispense only LNG
Fueling Station ▪ Concrete structure around storage
tank
o Required by code to contain all
LNG within storage in the event
of a severe leak

L/CNG Stations ▪ L/CNG stations make CNG from LNG
and can dispense either LNG or CNG
