Uniper completes first trials in Germany to transport LNG by rail
A subsidiary of German electricity company Uniper SE said it has successfully completed tests to transport liquefied natural gas (LNG) by rail in specialized tank cars, bringing the fuel transport mode closer to more use. wide across the world.
The rail logistics company Vtg AG carried out the first tests on behalf of Uniper’s Liqvis GmbH. Vtg moved the super-refrigerated fuel across the country from the ports of Brunsbüttel on the Elbe to a Uniper power station 500 miles away in Ingolstadt with no problem.
Liqvis, which operates LNG filling stations in Germany, is working to expand its transportation refueling network. It wants to transport more LNG by rail to its distribution centers and plans to make more use of the technology.
“The ability to move larger volumes in one lot per rail reduces transportation emissions while removing heavy traffic from the roads,” Uniper said.

LNG is mainly transported by ship and truck, but it has also been transported by rail in recent years in small quantities to Germany, Japan, Portugal, Spain and the United States. The fuel was largely transported in smaller ISO-certified, or International Organization for Standardization, containers.
VTG has developed a wagon with a thermally insulated tank to keep the gas at a constant temperature during filling and transport.
In the United States, widespread transport of LNG by rail was only allowed last year, when the Department of Transportation (DOT) finalized rules allowing bulk transport in specialized railcars. DOT-113C120W cryogenic tank cars are thicker and more puncture resistant.
A task force is studying the safety of transporting fuel by rail across the United States. No major incidents have been reported overseas, but the task force warned that more research is needed as larger quantities are transported in specialized tank cars.
