{lng} 101


Natural gas is a clean-burning fuel that produces fewer greenhouse gas emissions than other hydrocarbons. Common uses for natural gas include heating (home, schools and businesses), cooking food, generating electricity, fuel for industry and fuel for transportation like cars and buses. Growing markets in Asia would use natural gas as an energy source to replace higher emitting fuels, which could help reduce overall global GHG emissions.

Liquefied natural gas (LNG) is regular natural gas cooled to -162 degrees Celsius to convert it to a liquid. A LNG facility is similar to a refrigerator – it cools down the gas into a liquid form. When natural gas is converted to liquid, its volume is 1/600th of natural gas, allowing it to be transported efficiently and safely over greater distances. For example, the same amount of natural gas that would fill a hot air balloon is reduced in size to approximately what you could fit into a regular four litre milk jug.

The LNG industry is new to Canada, and comes with a lot of unfamiliar terms. We’ve put together a brief glossary of frequently used acronyms, words and phrases that you might not have heard before.

  • LNG: Liquefied natural gas (natural gas that has been cooled to -162 degrees Celsius)
  • LNG “train”: Industry term for a LNG facility. Called a train because the processing components of the facility are assembled back to back, similar to a train
  • MTPA: Million tonnes per annum (a measure used to quantify production at an LNG facility. For example, each LNG train at Pacific NorthWest LNG is expected to produce roughly 6 MTPA
  • FEED: Front end engineering and design. The planning and design stage of a major project where key engineering work takes place
  • BC EAO: British Columbia Environmental Assessment Office
  • CEAA: Canadian Environmental Assessment Agency
  • PRGT: Prince Rupert Gas Transmission Project
  • PRPA: Prince Rupert Port Authority
