Delaware Riverkeeper

New Fortress Energy subsidiary Energy Transfer Services’ permit allowing the transport of liquefied natural gas in special tank cars is set to expire next week, according to environmental group Delaware Riverkeeper.

The costs to electrify freight rail in the U.S., albeit expensive, extend beyond strictly capital costs to questions about electric grid reliability and how best to address decarbonization.

The groups say more federal oversight is needed for the transport of liquefied natural gas by rail.
