LNG (Liquefied Natural Gas)

What is LNG (Liquefied Natural Gas)?

Liquefied Natural Gas (LNG) is natural gas that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state.

Historical Background

LNG trade began in the 1960s. It has become increasingly important as a global energy source, allowing countries to access natural gas reserves that are not easily accessible via pipelines. India started importing LNG in the early 2000s.

Key Points

10 points
  • 1.

    LNG is primarily composed of methane (CH4).

  • 2.

    Cooling process reduces volume significantly, making it easier to transport by ship.

  • 3.

    Requires specialized LNG tankers for transportation.

  • 4.

    Regasification plants convert LNG back to gaseous form for distribution.

  • 5.

    LNG trade is governed by contracts between suppliers and buyers.

  • 6.

    Prices are influenced by global supply and demand, geopolitical factors.

  • 7.

    LNG is considered a cleaner alternative to coal and oil.

  • 8.

    India is a major importer of LNG, relying on it for energy security.

  • 9.

    Key LNG exporting countries include Qatar, Australia, and the United States.

  • 10.

    LNG infrastructure includes liquefaction plants, regasification terminals, and pipelines.
