Product

LNG is natural gas — predominantly methane (CH₄), with smaller fractions of ethane (C₂H₆), propane (C₃H₈) and other light hydrocarbons — that has been purified and cooled to approximately −161.4 °C (−258.5 °F) at near-atmospheric pressure, at which point it condenses into a cryogenic liquid. In this state, LNG occupies roughly 1/600^th the volume of natural gas at standard conditions, making non-pressurized storage and long-distance transport economically viable.​

LNG is odorless, colorless, non-toxic, and non-corrosive. Being lighter than air, any vapor released dissipates rapidly upward, reducing the risk of ground-level accumulation compared to heavier hydrocarbon fuels.​

Production & Supply Chain

The LNG value chain comprises four key stages: 

1. Upstream gas production, liquefaction at export terminals, 
2. Shipping via purpose-built cryogenic LNG carriers,
3. Regasification at import terminals
4. Injection into pipeline networks.

The development of large-scale liquefaction plants, cryogenic storage technology, and double-hulled LNG tankers effectively transformed natural gas from a purely pipeline-dependent commodity into a globally traded energy product, now competing directly with coal, oil and pipeline gas.​

Applications

LNG serves a broad range of end-use sectors:

• Power generation — used as a lower-emission replacement for coal and fuel oil in electricity plants
• Industrial fuel — provides high-temperature heat for cement, steel, glass, and ceramics production
• Maritime transport — increasingly adopted as a ship fuel to comply with IMO sulfur and emissions regulations
• Heavy road transport — fuels long-haul trucks where compressed natural gas (CNG) range is insufficient
• Remote and off-grid supply — delivers energy to regions without access to pipeline infrastructure
• Peak shaving — stored at distribution terminals to supplement pipeline gas during demand peaks, providing critical network reliability
