BP plc is advancing plans to develop more renewable natural gas (RNG) projects in the United States.


In the most recent deal, BP is joining Aria Energy to make RNG for transportation from captured methane from waste at three dairy farms in California. Nearly 10% of U.S. greenhouse gas emissions are estimated to be from the agricultural sector.

Digesters are to be installed at three dairy farms in the Central Valley to produce biogas from farm waste in the project, RNG Moovers. 

“RNG can play an important role in decarbonizing the transportation sector and helping BP and the world get to net zero emissions,”  said BP Senior Vice President Sean Reavis, who oversees the low carbon and trading business. 

Aria in 2017 purchased a half-stake in BP’s Mavrix LLC to distribute RNG to U.S. customers.

BP also has agreed to invest in a joint venture (JV) with Clean Energy Fuels Corp. to develop RNG production at dairies and other agricultural facilities. BP Products North America Inc. has provided $50 million for the JV, with Clean Energy providing $30 million.

Last fall Clean Energy said it planned to advance some RNG partnerships with BP and Total SE. Total is Clean Energy’s largest shareholder.

Paris-based Total also recently agreed to supply MSC Cruises with 45,000 tons/year of liquefied natural gas for a fleet of LNG-powered cruise ships operating from France’s port at Marseille. 

Meanwhile, Southern California Gas Co. (SoCalGas) and Anaergia, an anaerobic digestion technology firm, are teaming up to interconnect landfill gas supplies to the SoCalGas pipeline system in San Bernardino County.

Anaergia’s advanced anaerobic systems plan to produce up to 985 billion Btu/year of RNG by converting up to 300,000 tons of waste. Anaergia unit Rialto Bioenergy Facility LLC would own and operate the facility. It marks the fifth RNG production project in California that the Sempra Energy utility has connected to its distribution pipeline network.

“We’re now distributing RNG from nearly 25 dairy farms and more than 18 municipal refuse collectors,” said SoCalGas Vice President Jawaad Malik, chief environmental officer.

Also this month, Clean Energy opened another new public RNG fueling station in Carson, CA, near the Ports of Long Beach and Los Angeles. It is expected to fuel trucks from the ports and service terminals and warehouses.
