Philadelphia is advancing as an emerging natural gas export hub.

According to Reuters, Sunoco Logistics Partners is seeking state approval for its plan to build cryogenic tanks that can store up to 2.4 million barrels of natural gas liquids ("NGL") at a facility outside of Philadelphia.

According to the September filing with the Pennsylvania Department of Environmental Protection, the storage tanks would be capable of holding 1.5 million barrels of propane, 600,000 barrels of butane and 300,000 barrels of ethane.

Sunoco also announced earlier this month that they are moving forward with a $2.5 billion pipeline project (Mariner East 2) which the company projects will bring 275,000 barrels per day of natural gas liquids to its Philadelphia facility.
