The trucking industry is exploring the potential for heavy-duty vehicles to use LNG for long range journeys, while cutting greenhouse gas emissions, sulfur oxides and particulate matter, and reducing reliance on diesel. In the European Union, the LNG Blue Corridors project has proven the viability of establishing an LNG-fueling network for medium- and long-distance ground freight. Furthermore, LNG has potential for weight- and distance-intensive freight rail such as mine-to-port transportation. What does the future hold for LNG as a road and rail fuel? How can the ground and rail transportation sectors leverage this cleaner alternative to fuel oil and diesel?
