Estimated 15 million DGEs per Year for 140-Plus Trucks,
Gas Sourced from Landfill to Be Converted Directly to LNG
UPS said late last week that it will use biomethane to fuel upwards of 140 heavy duty trucks in Memphis and Jackson, Miss. behind a multi-year agreement with Memphis Light, Gas and Water (MLGW) and Atmos Energy Marketing. updated December 23 & 29
“Renewable natural gas is a critical part of our strategy to expand our fuel sources and minimize the environmental impact associated with growing customer demand,” UPS senior VP for global engineering and sustainability Mark Wallace said in a release.
“We are using methane that otherwise would be released into the atmosphere as a greenhouse gas emission and converting it to power our trucks while helping to promote the use of this renewable fuel in transportation,” Wallace said.
“Atmos will secure gas from the landfill and provide it to the Memphis utility for conversion to liquefied natural gas, says an MLGW spokesman. “MLGW will load the fuel into a third-party tractor-trailer to deliver to the UPS facility.”
The RNG will also be sold at both of MLGW’s public access CNG stations, says utility marketing specialist Allison Fouché.
The latest deal is part of an initiative announced earlier this year by UPS to significantly expand its use of RNG. According to the UPS announcement, “the company has a goal of driving one billion miles with its alternative fuels fleet, known as the Rolling Laboratory by the end of 2017, an effort that is reducing environmental impact and helping to advance new sustainability solutions and markets.”
More than 6,340 AFVs Operated by UPS
UPS notes that RNG, aka biomethane, can be derived from numerous sources, including decomposing organic waste in landfills, wastewater treatment and agriculture. The resulting product is often distributed through the natural gas pipeline system, making it available for use as LNG/liquefied natural gas or CNG/compressed natural gas – customers don’t necessarily get the bio-derived molecules although they buy the bio-dereived commodity.
For Jackson and Memphis, landfill gas is being processed directly into LNG for the UPS fleet.
Counting UPS’ propane autogas, ethanol, renewable diesel, and electric vehicles, “5.4 percent of total gas and diesel purchased was displaced” in 2014, the company says. The UPS fleet includes more than 6,340 all-electric, hybrid electric, hydraulic hybrid, CNG, LNG, propane and lightweight fuel-saving composite body vehicles.
