Introduction
Natural gas is a fossil energy source primarily composed of methane. It’s typically transported in its gaseous state via pipeline and serves as a primary energy source used for heating and generating electricity. The United States is the world’s leading natural gas producer, representing nearly a quarter of global production. To meet the growing need for natural gas in the international market, producers have turned to the use of natural gas in its liquefied form.
LNG Basics
Liquefied natural gas, or LNG, is a natural gas that has been cooled to a liquid state (about -260 degrees Fahrenheit) for transport and storage. The volume of gas in this liquid form is about 600 times smaller than its gaseous state, making it much easier to be transported. This enables international markets that are far from producing regions to still have access to natural gas.
Liquefying natural gas is one way to transport natural gas long distances where pipelines aren’t feasible. In its condensed form, LNG is shipped in special storage tanks to terminals all around the world. At these terminals, the LNG is returned to its gaseous state where it can be transported by pipeline to power plants, industrial consumers, and distribution companies.
LNG Usage
For large-volume ocean transport, LNG ships are equipped with sophisticated leak detection, advanced radar systems, and numerous other technologies to ensure safe transportation. Once the ship enters the receiving port, LNG is off-loaded into storage tanks and later regasified for transport via distribution pipeline networks.
LNG is also transported in smaller quantities, usually by truck or shorter ocean distances. Power plants use a technique called peak shaving to level out energy consumption by storing LNG during months of low usage. During peak demand, customers can tap into the LNG supply to maximize the performance of their energy grids.
