(Reuters) – As politicians debate the dangers of a massive increase in oil carried by rail in North America, railroads and energy producers are considering the same for natural gas.

Buoyed by the unexpected success of crude by rail, companies are beginning to consider transporting natural gas as remote drilling frontiers emerge beyond the reach of pipelines, executives said.
Natural gas by rail is years away and likely to face strong public resistance after a series of explosive crude-by-rail accidents. But the potentially multibillion-dollar development could connect gas-rich regions like North Dakota with urban centers, presenting an opportunity for railroads, drillers and tank car makers already cashing in from hauling oil on trains.
It could also be a cure for environmentally unfriendly flaring, a growing problem in far-flung areas where more than $1 billion of natural gas produced alongside oil is burned off each year for lack of processing plants or pipelines that can take years to build.
“Everyone is talking about moving gas by rail,” said David Demers, chief executive officer of Westport Innovations, which is developing technology for natural gas-powered locomotives. “They see this as a large opportunity and have their pencils out to see how it could work.”
Demers said Berkshire Hathaway’s BNSF was one railroad considering the move.
BNSF declined to comment on its plans, but a spokeswoman said it would take time for any development of gas by rail.
Transporting gas by rail, most likely as cryogenic liquefied natural gas (LNG), faces obstacles. The technology is in its infancy, and so far no tank car is permitted to carry the fuel on U.S. rails. Nor are there enough plants that convert natural gas to LNG to support a robust gas-by-rail market, experts said.
More-volatile liquids like ethylene and propane already travel on the rails in growing volumes. But as concerns about the safety of crude by rail intensify, regulators are exercising extreme caution with uncertified fuels like LNG, said executives involved in developing the technology.
Stressing that it is too early to say, many of the major Class 1 railroads that have embraced crude by rail declined to speak about specific plans for gas by rail. Calgary-based Canadian Pacific Railway Ltd, for example, was just “monitoring any discussions in this area,” a spokesman said.
Breitling Energy Corp CEO Chris Faulkner said he and other gas producers were discussing the idea, but his company was not considering it.
“I can only imagine the amount of pushback we’re going to have on transporting gas by rail,” Faulkner said. “The discussion isn’t about safety and fact, it’s about fear.”
But as railroads team up with companies like General Electric Co and Caterpillar Inc to develop technology to run locomotives on LNG, many say that hauling the fuel as cargo is the next step as a drilling revolution transforms North American energy markets.
“A LOT OF MONEY”
LNG, natural gas cooled and shrunk to a liquid for shipping, already powers heavy-duty trucks and boats in the United States and Canada. A network of fueling stations is cropping up with backing from the likes of Royal Dutch Shell Plc and Clean Energy Fuels Corp.
Small-scale refrigeration plants that can turn gas to LNG are being built in drilling regions to reduce gas flaring. In remote North Dakota, one-third of the gas produced is flared.
Now, gas by rail is emerging as a possibility. Energy producers have approached Jacksonville, Florida-based CSX Corp about moving LNG by rail, said Louis Renjel, vice president of strategic infrastructure initiatives, but the company has no plans to do so.
