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 2018. Topics included:
  • Moving Towards a Sustainable Energy and Transportation Future
  • U.S. and Global Perspectives on the Renewable Natural Gas Opportunity
  • Ultra-low Carbon Renewable Natural Gas and Its End-use Markets
  • Programs, Technologies and Approaches to Bring Renewable Gas to Market
  • Organics Diversion as a Driver for RNG Project Development
  • The Role of State and Local Agencies in Advancing RNG in California

  • 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. 
  • Design Principles for a Renewable Gas Standard*: This ICF White Paper explores the possibility of a Renewable Gas Standard that would require gas providers to procure a certain amount of RNG, measured against benchmarks such as carbon reduction or volume. 
  • 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.
  • Optionality, Flexibility & Innovation*:  This study by Energy Futures Initiative analyzes the options for meeting California’s near and long-term carbon emission reduction goals, within the parameters of existing state policy. 
  • Policy Options to Facilitate Renewable Natural Gas Use and Development*:  This document summarizes the policies to support RNG use beyond the transportation and electric sectors.
  • Natural Gas Utility Business Models for Facilitating Renewable Natural Gas Development and Use*: This document summarizes natural gas utility business models to promote RNG use while using existing core competencies.
  • Renewable Natural Gas: Potential Supply and Benefits*: This document explores both existing and potential RNG supplies in the U.S. and discusses environmental and economic benefits of RNG.
  • Renewable Natural Gas Project Economics*: This document provides an overview of RNG economics, project costs, incentive programs, and the potential for decreasing payback periods.
