What is LNG?

Liquified Natural Gas (LNG) is natural gas (methane) - the same clean, safe energy source used to fuel our homes and industries - that has been reduced to 1/600th its volume through a sophisticated refrigeration process that cools the gas until it liquefies (minus 260 degrees fahrenheit)" LNG".

  • LNG is liquid natural gas which has been super-cooled to
    -260°F and changed from gas to liquid
  • Liquefaction reduces volume by 600-to-1
  • Stored cold in insulated containers at near atmospheric pressure
  • LNG is colorless, odorless, non-corrosive, and non-toxic
  • Becomes lighter than air when vaporized

Liquefied Natural Gas is widely recognized as an environmentally friendly fuel source. Unlike other fossil fuels, it is non-carcinogenic and non-toxic. Because it is lighter than air, it dissipates quickly and has shown to pose little threat to marine life when transported. In the history of LNG oceanic transportation, there have been no incidents of containment loss. If such an incident were to occur, LNG would not mix with the water or form slicks that could harm flora or fauna.

When liquefied, impurities such as sulfur, carbon dioxide, mercury and water are removed from natural gas and safely disposed of. This creates a product that is clean burning and safe for the environment. On average, LNG particle emissions are near zero. When compared to other fossil fuels, CO2 emissions are reduced by 70 percent.

When in a liquid form, natural gas can be shipped long distances safely and economically in specially designed ships with insulated storage tanks. LNG has the appearance of mineral water and is neither shipped nor stored under pressure. Therefore, LNG fires are highly unlikely because of the extremely delicate fuel to oxygen balance necessary for combustion. The industry has, however, put in place extremely aggressive safety measures to ensure that fires are prevented and spills are contained.

Cheniere's safety processes exceed these stringent government regulations, ensuring a clean fuel source and security for our neighbors and our communities.
