What is LNG?

Liquefied natural gas, or LNG, is natural gas in a liquid form. When natural gas is cooled to minus 259 degrees Fahrenheit (minus 161 degrees Celsius), it becomes a clear, colorless, odorless liquid. LNG is neither corrosive nor toxic. This liquid form allows large volumes of natural gas to be transported to locations unreached by gas pipelines.

MLGW operates a LNG storage facility, which allows for the storage of gas during the summer periods of low usage and then is used as a reserve during winter peak periods. The facility stores one billion cubic feet in an above-ground storage tanks. MLGW also sells LNG from this plant as vehicle fuel as well as maintains 5.8 billion cubic feet of underground natural gas storage.

LNG as a Transportation Fuel

MLGW supplies LNG for United Parcel Service’s fleet operation in the Greater Memphis area.  As part of the UPS “rolling laboratory” approach to alternative fuel technologies, 59 new LNG tractor trailers have been deployed in Memphis.  MLGW supported UPS in their recent installation of a LNG fueling station on the company’s property on Swinnea Road and has created a flagship LNG customer.
