SoCalGas and CR&R Environmental to Construct New RNG Pipeline

Southern California Gas Co. (SoCalGas) and waste management company CR&R Environmental broke ground on construction of an eight-inch pipeline that will bring carbon-neutral renewable natural gas (RNG) into the SoCalGas distribution system for the first time. Renewable natural gas from the digestion facility will be designated specifically to power CR&R’s fleet of approximately 900 waste hauling trucks.

The connecting pipeline, funded by CR&R Environmental, will reach approximately 1.4 miles from an existing SoCalGas pipeline to a new CR&R anaerobic digestion facility in Perris, California slated to be complete this spring.

“Bringing renewable gas into our pipeline system is a big step forward for SoCalGas and for California,” said Lisa Alexander, SoCalGas’ vice president, customer solutions and communications.  “Using our pipeline infrastructure to distribute this carbon-neutral fuel will help to slow climate change and meet state goals for increasing use of renewable fuels. We see this de-carbonization of our pipeline system as the way of the future.”

CR&R’s Perris anaerobic digester, supplied by Eisenmann USA and Greenlane Biogas and constructed by W.M. Lyles, will use source-separated organic waste collected in cities’ green collection carts to produced carbon-neutral renewable methane. This gas will then be further refined using pollution-free technology and distributed through SoCalGas’s pipeline infrastructure. CR&R’s Perris digestion facility is believed to be the largest in the world.

Studies indicate California could produce almost 300 billion cubic feet of RNG per year just from organic waste. Instead of landfilling or burning that waste, California could use it to replace 75 percent of all the diesel fuel used by motor vehicles in California.

SoCalGas expects it will be able to bring renewable gas from the facility into its pipelines by June of this year.
