Transportation Fuel

Marine Fuel

Compared to oil-based alternatives currently used for marine fuel, LNG emits significantly lower levels of nitrogen oxide, sulfur oxides, particulate matter and carbon dioxide. New emissions standards, in addition to the low cost of natural gas compared to more conventional fuels, have encouraged the use of LNG as a marine fuel by the shipping industry in recent years. This growth is expected to continue: The U.S. is projected to almost double its current fleet of LNG-fueled tankers from 2016 to 2019, according to the U.S. Energy Information Administration, and worldwide, the global fleet of LNG-powered ships is expected to grow more than 40-fold to almost 1,800 vessels by 2020, according to DNV GL.

IMO 2020

As IMO 2020 approaches, LNG offers an opportunity for the maritime community to reduce pollutants and emissions. As the global fleet of LNG-powered ships is expected to grow, so to will LNG bunkering. To stay up to date on the latest IMO 2020 news and developments, be sure to check out DNV GL’s resources on LNG bunkering infrastructure and be sure to check out our op-ed on how U.S. LNG stands to succeed from IMO2020.

Vehicles

Compressed natural gas (CNG) and liquefied natural gas (LNG) are both used as vehicle fuels, however LNG is better suited for heavy-duty vehicles traveling long distances.

The expanded use of natural gas as a transportation fuel, whether in the form of LNG or CNG, can help reduce air pollution and carbon emissions from the transportation sector: On a well-to-wheel lifecycle basis, vehicles powered by natural gas emit between 13 and 21 percent fewer greenhouse gas emissions compared to gasoline and diesel-powered vehicles. Natural gas powered vehicles can also improve local air quality as they emit approximately 80 percent fewer non-methane hydrocarbons and 50 less NOx gas.

Continued growth in the use of natural gas as a vehicle fuel – the number of natural gas vehicles around the world increased by an estimated 300 percent between 2006 and 2014 – will help improve air quality and reduce carbon emissions. And more rapid growth is expected. This video demonstrates how LNG can be used as fuel for heavy duty trucks.
