Liquefied Natural Gas: Everything You Need to Know

If you’re interested in learning more about liquefied natural gas (LNG), you’ve come to the right place! Here, we explain what LNG is, how it’s created, and why it’s so popular among businesses looking to reduce their carbon footprint.

What is liquefied natural gas?

Liquefied natural gas, or LNG, is a type of natural gas that has been cooled and condensed into a liquid form. This process makes it easier to store and transport LNG, and it also makes it less flammable than traditional natural gas. It’s estimated that the use of LNG could cut greenhouse gas emissions by up to 20% when compared with other fossil fuels like coal and oil.


Is it safe?

LNG is safe when handled properly. That’s why there are comprehensive LNG project management systems in place, designed to ensure the safety of people, communities, and the environment.

LNG projects must undergo thorough reviews by many agencies, including federal regulatory bodies like the Federal Energy Regulatory Commission (FERC). The federal guidelines for LNG projects follow the National Environmental Protection Act (NEPA), which consists of exhaustive studies on potential impacts to safety, the environment and the surrounding communities. It now includes a review of carbon emissions. Once construction begins, specific agencies review and monitor construction practices.


Are there any safety concerns with LNG facilities?

LNG is natural gas that has been cooled to -260°F, at which point it becomes a liquid. This process makes it easier and cheaper to transport natural gas over long distances. Safety concerns with LNG facilities are minimized through the stringent reviews by federal, state and local regulatory agencies. LNG is not easily flammable in its cryogenic state and when it does ignite, it results in a ‘lazy flame’ and does not typically result in explosions.


How do LNG facilities respond to spills and leaks?

LNG facilities are designed to contain and control any spills or leaks that may occur. In the event of a spill, the first priority is to stop the flow of gas. Once the gas is shut off, the next priority is to prevent the spread of the spill. Secondary containment systems, like dikes and berms, are used to contain any spilled LNG. Finally, specialized equipment is used to clean up the spill and return the area to its original condition. While these measures have been successful in preventing significant environmental damage, accidents can still happen. These incidents have occurred at production plants as well as at storage terminals. The severity of such accidents depends on where they happen and how much gas was released.


Can we use other gases as a substitute for LNG in vehicles, power plants, or households (e.g., propane)?

Yes, other gases can be used as a substitute for LNG in vehicles, power plants, or households. Propane, for example, is a common substitute for LNG. However, there are some important differences between these two gases that you should be aware of before making a decision. For instance, propane has less energy density than LNG does. In addition, propane costs more than LNG does on an energy-equivalent basis because it takes more propane than LNG to produce the same amount of heat or electricity.
