  • SoCalGas Pipelines Flow with Californian RNG

    Renewable natural gas is a fuel with impeccable credentials: locally-produced; carbon-neutral; renewable and sustainable; harvested from wasted energy; reduces greenhouse gas emissions; and conserves landfill space. Southern California Gas Co. (SoCalGas) and waste management company CR&R Environmental (CR&R) are taking advantage.

    The collaborators announced they have begun injecting renewable natural gas produced at CR&R’s anaerobic digestion facility in Perris, Calif., into SoCalGas pipelines. This is the first renewable natural gas produced within California to be introduced into SoCalGas’ pipeline system.

    Clean air can't wait - push for RNG in trucking (Video Clip)

    Todays affordable natural gas trucks are the clear solution for cleaner air. They are certified to run 90 percent cleaner than diesel trucks, with emissions so low that they are comparable to electric trucks. And when fueled by renewable natural gas captured from organic waste streams, we can dramatically improve greenhouse gas emissions and provide cities with new opportunities for economic and job growth.

    A 2016 white paper by Gladstein, Neandross & Associates published in 2016 titled, Game Changer: Next Generation Heavy-Duty Natural Gas Engines Fueled by Renewable Natural Gas contains a chart showing carbon intensity rating of key transportation fuels. It is reported in the paper that UC Davis found that anaerobic digestion of readily available California organic waste (dairy manure, landfill gas, municipal solid waste and wastewater) could potentially produce nearly 675 million DGE per year of RNG, or enough RNG to fuel 31 percent of California’s Class 8 heavy-duty trucks.

    Heavy Duty Vehicles powered by near-zero-emission natural gas engines have tailpipe nitrogen oxide (NOx) emissions that are comparable to — or possibly lower than — the amount of NOx emitted to produce electricity used to charge similar heavy-duty battery electric vehicles. This is due to the relatively high NOx emissions rates from a portion of the existing power plant mix — particularly in regions that rely heavily on coal-based electricity generation.

    Support for the research was provided by a number of public and private sector organizations, including: Agility Fuel Systems, American Gas Association, California Natural Gas Vehicle Partnership, Clean Energy, Pacific Gas & Electric Company, South Coast Air Quality Management District and Southern California Gas Company:

      Cliff Gladstein for gna July 27, 2018 - New Approach to Trash is Displacing Fossil Fuels

      In early July 2018, renewable natural gas (RNG) began to flow into Southern Californias natural gas distribution system from a state-of-the-art high solid anaerobic digester (HSAD) in Perris, California, that processes organic waste that would otherwise have been sent to a landfill. Because the waste will no longer have an opportunity to naturally decompose at a dumpsite and emit harmful greenhouse gases, the RNG being produced and delivered into the pipeline has a negative carbon profile. This first-of-its-kind project was made possible by the innovation, investment, and commitment of CR&R, a leading waste and recycling collection company.

      Well known to those familiar with bioenergy and innovative waste management in the U.S., the CR&R anaerobic digestion facility is at the vanguard of an emerging trend to reduce greenhouse gases and more sustainably manage municipal refuse. The intrinsic value of CR&R’s natural gas is that it is 100% renewable as it is produced as a matter of course from the normal daily activities of the tens of thousands of residents whose waste food, grass clippings and other organic garbage would otherwise be dumped in local landfills.

      CR&Rs facility, in Perris, CA, takes food and green waste from more than a dozen cities throughout Southern California, processes it (i.e. sorts through the material to remove all plastics, metals and other inert material), grinds it, and dumps the refined material into digesters. There the organic mix will sit for about a month, consumed by voracious microbes that are optimized to consume the organic matter, reduce its mass, and convert about half of it to carbon dioxide and methane. The methane is then sucked out of the digesters, cleaned to pipeline quality natural gas – that is pretty much indistinguishable from natural gas from fossil sources – compressed and injected into a nearby gas distribution line. CR&R then consumes the RNG that it produces in the very trash trucks that pick up the organic garbage from the company’s customers.
