Renewable Natural Gas Emerging as Serious Decarbonized Gas Contender

Last December, two giant Virginia-headquartered firms—energy company Dominion Energy and food manufacturer Smithfield Foods—announced completion of a novel renewable natural gas (RNG) facility in Milford, southwestern Utah. While the Milford facility is the first of four similar projects that Align Renewable Natural Gas—a joint venture formed in November 2018 between Dominion and Smithfield—is spearheading, it is just one of a string of new, notable developments that suggest RNG is quickly gaining ground as the energy transition unfolds.

 

RNG is essentially a gaseous fuel derived from biogenic or other renewable sources, which can be “upgraded” and processed to pipeline-compatible, near-pure methane. According to the World Resources Institute (WRI), landfills account for the bulk of current RNG production, mainly because they already have methane collection mechanisms. A smaller share of RNG is derived via anaerobic digestion (AD) of solid organic matter removed in the wastewater treatment process at municipal water resource recovery plants, animal manure at livestock farms, and food waste at other facilities. RNG can also come from gasification of “dry” organic wastes, such as agricultural and forestry residues.
