LNG Benefits

LNG is


Liquefied natural gas (LNG) is less expensive than conventional fossil fuels such as gasoline and diesel. Puget LNG converts clean-burning natural gas into LNG to provide to marine and over-land transportation customers. While converting the operations of your vessels and vehicles to use LNG takes investment, the payback on that investment begins right away with lower fuel and operating costs.

Puget LNG is connected to the Williams Northwest Pipeline and sources natural gas from British Columbia in Canada, trading through the Sumas Hub. The Sumas Hub predominantly supplies natural gas to the Northwestern United States and is less influenced by some of the broader gas markets in the USA. The price of natural gas typically trades lower at the Sumas Hub than the more well know Henry Hub.

Puget LNG welcomes the chance to work with customers to source their natural gas with a flexible approach to contract structures. We have the ability to provide a stable or floating monthly indexed natural gas commodity price or simple liquefaction tolling for customers with procured gas.

Puget LNG is happy to work with you to realize a positive impact on your bottom line, the local economy and the environment.


Natural gas is the cleanest burning fossil fuel. When cooled, natural gas becomes LNG and is a cleaner fuel alternative to oil-based fuel such as diesel, making it an environmentally responsible choice. This is true even when evaluating direct, upstream and end use GHG emissions.

LNG fuel cuts particulate matter (PM) emissions produced by ships by more than 85%, improving public health. It also reduces greenhouse gas emissions (GHG) by nearly 15%, sulfur dioxide (SOx) emissions by over 99% and nitrogen oxide (NOx) emissions by nearly 85%. Another important environmental advantage of LNG as fuel is that in the unlikely event of a spill, LNG turns into vapor and dissipates with no lasting effects on water or marine life.

The natural gas used to make LNG can also come from renewable sources, made entirely from organic waste. These waste streams can come from sources such as sewage and food or animal waste. The renewable gas is typically generated through a process called anaerobic digestion. Natural gas from renewable sources can offer a very compelling greenhouse gas benefit to customers over conventional fuels.


LNG is simply the liquid form of the natural gas used in millions of homes and vehicles. When cooled, natural gas is reduced to a liquid that is one six-hundredth the volume, making it easier to store and transport. It is not explosive or flammable in its liquid state.

As described by the U.S. Department of Energy (DOE), the physical and chemical properties of LNG render it safer than other commonly used hydrocarbons. For more than 40 years, the safety record of the global LNG industry has been excellent, due to attention to detail in engineering, construction and operations. LNG needs to be exposed to ambient temperatures to vaporize and the resulting vapor is only flammable within a narrow range of gas-to-air ratio, making combustion highly unlikely in the case of a leak.

To ensure safe operations, the Tacoma LNG facility has been designed in accordance with Federal and State agencies guidelines and standards. The facility has been designed to meet or exceed code compliance and provides additional layers of protection from an unsafe event. An independent safety report commissioned by the Tacoma Fire Department evaluated the project design and compliance and found no credible failure scenarios for the LNG tank, noting “the Tacoma LNG plant was designed to the applicable codes and standards with significant attention to detail and a perceived objective of becoming a best in class LNG facility.” The report goes on to say that some features “go beyond code compliance to provide additional layers of protection” and that that the full containment tank for the Tacoma facility has a “robust design suited for the local conditions,” which includes design features of a safe shutdown in case of an earthquake without loss of containment.
