Additional Information and Resources

SoCalGas® hosted a comprehensive one-day workshop on Renewable Natural Gas at its Energy Resource Center in Downey, CA, in the fall of 2016. Topics included:
  • Case Studies: Turning Waste into Vehicle Fuel or RNG
  • The Role of State Agencies in Advancing RNG
  • From Biogas to RNG: Overview of Biogas Upgrading Technologies & Utility Interconnection
  • Biogas/RNG End-use Applications
  • Exploring the Economic/Policy Landscape
  • The Role of Renewable Gas in a Renewable Future
  • SoCalGas RNG Tool Kit - SoCalGas has developed a tool kit to help educate the public on RNG and assist developers who may be interested in interconnecting to the SoCalGas pipeline network. 
  • American Biogas Council (ABC) Resource Library*: The ABC is the SoCalGas national organization dedicated to creating jobs, environmental sustainability and energy independence by growing the American biogas industry. They maintain a collection of various resources, including a profile of California’s biogas market*.
  • American Gas Foundation “The Potential for Renewable Natural Gas” research paper*: This paper from 2011 was prepared by the Gas Technology Institute (GTI) and explores the opportunity to produce renewable gas nationwide to supplement pipeline natural gas. It includes findings on costs, production potential, and environmental and economic benefits.
  • Bioenergy Association of California (BAC) 2015 whitepaper*: This whitepaper describes the opportunity to produce RNG in California, and offers the concept of a “Renewable Gas Standard” to promote the development of this nascent market.
  • Biogas Upgrading Technologies Study: SoCalGas commissioned Black & Veatch to perform a characterization and evaluation of current biogas upgrading technologies that would allow the injection of upgraded biogas into SoCalGas natural gas pipelines, with a focus on technology availability, performance, cost, and future R&D recommendations. This paper from April, 2016, provides a high level overview of the analysis performed and key findings
  • CARB Short Lived Climate Pollutant (SLCP) Website*: This California Air Resources Board (CARB) website contains the latest information on California’s effort to reduce SLCP emissions, including methane. The SLCP plan* contains various estimates and projections regarding project potential for reducing methane emissions at facilities like dairies and landfills.
  • CARB Low Carbon Fuel Standard (LCFS) Program*: California’s LCFS program aims to reduce greenhouse gas (GHG) emissions associated with fueling the state’s transportation sector by creating a market-based credit trading program where high-GHG fuels can purchase credits produced by lower-GHG fuel providers to comply with the required reduction. The current program goal aims to reduce the GHG intensity by 10% by 2020, and future program goals are under development. Transportation fuels are assigned “well-to-wheels” GHG intensities*, which contemplate full supply chain and end-use GHG emissions. Renewable Gas pathways typically provide 60-400% GHG reduction compared to traditional diesel or gasoline.
  • CARB/CalEPA Report: The Feasibility of Renewable Natural Gas as a Large-Scale, Low-Carbon Substitute Changer Technical White Paper*:  This study examines the feasibility of producing large quantities of renewable natural gas fuels for use in transportation in California.
  • Database of State Incentives for Renewables & Efficiency (DSIRE)*: DSIRE provides a searchable, comprehensive source of information on incentives and policies that support renewable energy and energy efficiency in the United States.
  • Game Changer Technical White Paper*:  This White Paper explores the need – and leading approaches – to immediately start deploying zero-emission and near-zero-emission heavy-duty vehicle (HDV) technologies on a wide-scale basis in the United States.
  • US Department of Energy (DOE) Bioenergy Technologies Office (BTO)*: The BTO conducts research on biofuels development, including the “Billion Ton Studies” which explore the potential organic feedstock available to produce biofuels.
  • US Environmental Protection Agency (EPA) AgSTAR Program*: Provides various resources to promote the use of biogas recovery systems to reduce methane emissions from livestock waste, including outreach materials and project development tools, funding resources, information on operating digesters, pre-feasibility analyses, and other resources. This infographic* highlights some key information about the program activities over the last 20 years.
