The Puget LNG Plant
Puget LNG’s waterside location in the Port of Tacoma is ideal for providing LNG to a marine customer base, with easy access to rail and on-road transportation corridors.
Puget Sound Energy and Puget LNG (a subsidiary of PSE’s parent company Puget Energy) are building a $310 million LNG plant in the Port of Tacoma.
The plant will have a shared function, providing LNG for Puget LNG’s commercial customers and also providing necessary domestic supply back up for Puget Sound Energy’s customers.
- Shoreside direct loading access
- Designed to meet marine fueling requirements
- Water loading access with a flow rate of 2,640 gallons/min
- 2 tanker truck loading bays with a flow rate of 300 gallons/min
- 225,000 gallons per day liquefaction (expandable)
- 2.2 million gallons of LNG storage
- Rail spur on site for future potential rail car loading
Construction at the plant is currently underway and it will be in production by October 2019.
The focus of Puget LNG is to provide LNG to transportation customers within the Puget Sound region. The waterside location in the Port of Tacoma is ideal for providing LNG to a marine customer base; however, there is also easy access to rail and on-road transportation corridors.
LNG is considered to be the best fuel option to meet the International Maritime Organization’s 0.5% global Sulphur cap for marine fuels which comes into effect in 2020. This reduction from the current standard of 3.5% Sulphur is in addition to other Sulphur caps on marine fuels within existing Environmental Control Area’s (ECA’s) in various regions, particularly within the coastal regions of the continental United States and Canada.
LNG meets all of these requirements as it contains virtually no Sulphur (typically about 0.004% on a mass to mass basis). This allows for a LNG fueled ship to operate in all regions without the need for fuel switching or expensive exhaust scrubbers.
Additionally LNG has other distinct benefits over traditional oil-based marine fuels such as;
- Lower NOx, SOx, PM and GHG over HFO without the need for complicated exhaust clean up systems
- Less environmental risk in the case of a fuel spill
- Abundant supply of natural gas and dedicated marine fuel terminals means price stability and dedicated supply chain
With the Port of Tacoma location of the Tacoma LNG plant, Puget LNG is ideally placed to fulfill the LNG fueling needs of the marine industry in Puget Sound. The facility is designed specifically to meet maritime fueling requirements with shoreside direct loading access.
TOTE Maritime is a leader the industry in environmental responsibility through many environmental initiatives including plans to convert their vessels to liquefied natural gas power (LNG).
In 2015, TOTE introduced two LNG-powered containerships to the Puerto Rico trade. These Marlin-class vessels are the most advanced, environmentally responsible vessels of their kind – resulting in a 98% reduction in nitrogen oxide emissions, 97% reduction in sulfur oxide and a 72% reduction in carbon dioxide emissions.
TOTE is converting to duel-fuel, the engines of the two Orca-class container ships that travel from Tacoma to Alaska. These vessels will also surpass the standards put in place by the U.S. Environmental Protection Agency’s clean air regulations.
LNG fueling is one of several advanced technologies being considered to make big changes in the railroad business.
Major railroads like Union Pacific and Burlington Northern Santa Fe for example, are forging ahead with what could be the next big step in motive power: locomotives fueled by LNG. The two major motive power suppliers, EMD and GE, are developing and intensively testing engines and will soon have LNG fueled locomotives in revenue-service evaluation in a variety of locations across the US.
With Puget LNG’s location in the Port of Tacoma, major rail lines and inter-modal yards are in close proximity. The Tacoma LNG plant site is accessible by rail, with a spur onto the site, giving future potential for directly fueling LNG tender railcars.
On-Road Transportation Markets
Used in trucks delivering goods, LNG has the potential to offer fuel cost savings when compared to conventional diesel. It can also reduce sulphur emissions, particulates and nitrogen oxides, and help reduce greenhouse gas emissions.
Natural gas engines are available for a variety of applications from Class 8 trucks to local delivery trucks. In the Puget Sound region there are already vehicles on the road using LNG. For example Potelco and Interstate Trucking have LNG vehicles in their fleets, using existing LNG fueling locations in the region.
Off-Grid Industrial Markets
The ability to transport LNG and the energy density makes LNG a very suitable fuel for industrial customers who are outside of natural gas service areas. This could be locations where pipeline natural gas is not available or available in required volumes.
Transporting LNG to an industrial location for use in applications such as kilns or steam generation for example, creates a “virtual pipeline”. This allows off-grid industrial customers to benefit from the operational and environmental advantages of natural gas over other fuel types.
Puget LNG is happy to explore opportunities to bring natural gas in the form of LNG to your location.
Liquefied natural gas (LNG) is less expensive than conventional fossil fuels such as gasoline and diesel. On average, LNG is 30% more affordable than oil or coal. Puget LNG converts clean-burning natural gas into LNG to provide to marine and over-land transportation industries.
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 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 burned it emits half as much carbon dioxide than coal. It is colorless, odorless, non-corrosive and non-toxic. When used in transportation applications and replacing oil-based fuels such as diesel, natural gas produces fewer greenhouse gases, making it an environmentally responsible choice. It is so clean burning that it is used all over the world to heat homes, cook, generate electricity and fuel vehicles, while emitting significantly lower levels of carbon dioxide and sulfur compared to other fossil fuels.
Natural gas can also be provided from renewable sources, made entirely from organic waste. These waste streams can come from sources such as sewage, food or animal waste and are generated typically through a process called anaerobic digestion. Natural gas from renewable sources can offer a very compelling green-house gas benefit over conventional fuels to customers.
Liquefied Natural Gas is a very safe fuel that is used in many varied applications around the world. 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.” In its liquid state natural gas will not burn and is not explosive. 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 plant has been designed in accordance with the various Federal and State agencies guidelines and standards. As stated by the Federal Energy Regulatory Commission (FERC), the focus on sound engineering practices within the industry leads to LNG’s “remarkable safety record,” particularly when looking at the movement of LNG by ship. More than 77,000 LNG cargoes have been safely delivered, leading the DOE to conclude that “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.”
