CPUC Issues Proposed Decision on Voluntary RNG Tariff

The CPUC has issued a Proposed Decision that would adopt a voluntary tariff for customers of SoCalGas and SDG&E to choose to purchase biomethane.  The tariff requires that at least half of the biomethane purchased by the utilities is generated in California and half of that portion must come from sources other than landfill gas to help California meet is Short-Lived Climate Pollutant and waste reduction goals.  The tariff will include biomethane generate from biomass conversion (gasification and pyrolysis) as well as the biomethane from anaerobic digestion of organic waste.  The Proposed Decision would approve the voluntary tariff as a three-year pilot program and will then assess whether to make it permanent or replace with a biomethane procurement program.

WATCH: CalBio Opens Kern County’s First Dairy RNG Project

CalBio hosted a virtual opening of its dairy digester cluster project in Kern County.  This is the first dairy waste to Renewable Natural Gas (RNG) project in Kern County and will provide many benefits to the County and beyond, including production of carbon negative fuel that can replace diesel, improvements to air and water quality, job creation, and economic development.

Watch the video of this exciting event here.

Gladstein Neandross Releases New CA RNG Report

Gladstein Neandross & Associates has just released an important report detailing the RNG (renewable natural gas) projects expected to begin producing vehicle fuel from California’s organic waste in the next four years.  Some of the highlights of GNA’s report are:

  • California will have 160 RNG production facilities online by the end of 2024
  • Those facilities will produce a combined 119 million diesel gallon equivalents of low carbon and carbon negative vehicle fuels, enough to fuel 13,731 natural gas trucks
  • The average carbon intensity of the California produced RNG will be negative 101.74 gCO2e/MJ
  • Over the next 15 years, trucks running on this RNG will cut climate pollution by 51.4 million metric tons and will cut smog-forming pollution by 20.8 thousand metric tons per year.

Greenlane Biogas Announces Dairy Biogas Upgrading Projects

Greenlane Biogas has signed $15.2 million in new supply contracts using Greenlane’s Pressure Swing Adsorption (“PSA”) biogas upgrading system. The contract is for the supply of biogas upgrading and related equipment for a cluster of dairy digesters located in California. Greenlane’s biogas upgrading systems will generate renewable biomethane for injection into the local gas distribution network owned and operated by PG&E.

SoCalGas Announces New Technology to Convert CO2 to Renewable Gas

SoCalGas and its partners, PG&E and Opus 12, have announced the development of a new one-step process to convert carbon dioxide to renewable gas.  This is a very important development as it will provide a way to convert excess solar and wind power to long-duration energy storage (in the form of renewable gas), which is critical to reach 100 percent renewable energy.  It will also reduce emissions from bioenergy by capturing CO2 emissions and converting the carbon to renewable gas.

Air Board Prepares for New Climate Change Scoping Plan

At the Air Board’s April hearing, Air Board staff provided an overview of the next Climate Change Scoping Plan update, including the timeline to develop the plan and some major new areas it will include. The Scoping Plan provides the framework for achieving California’s climate goals.  Air Board staff proposed several new focus areas for the next Scoping Plan that are directly related to bioenergy, including:

  • Consideration of a renewable gas procurement requirement
  • A plan for achieving carbon neutrality by mid-century
  • Incorporating Natural and Working Lands into the Scoping Plan

New Report Highlights Importance of Bioenergy to Meet Climate Goals

Lawrence Livermore National Labs has just released a groundbreaking report on how California can reach carbon neutrality by mid-century.  The report finds that reaching carbon neutrality is feasible with existing technologies, but only if California invests much more in carbon negative actions that can offset the carbon emissions that can’t be eliminated.  The report highlights several areas where carbon negative emissions are achievable and quite cost-effective:  Bioenergy, biochar and other forms of carbon sequestration, restoring natural and working lands, and carbon capture and storage.  Of these, the report concludes that bioenergy will provide the greatest share of carbon negative emissions by mid-century, and at a small fraction of the cost of carbon reductions under California’s Low Carbon Fuel Standard or Cap & Trade programs.

BAC member Anaergia wins $5 million CEC grant !!

Anaergia’s Rialto facility has received a $5 million award from the California Energy Commission to convert organic waste to carbon negative transportation fuels.  The project will help the state to meet its Short-LIved Climate Pollutant reduction requirements and will provide benefits to air quality, local economic development and clean energy jobs. When complete, the project will divert 85,800 tons per year of food waste from California landfills.  It will convert that waste to more than 2.5 million diesel gallon equivalents (DGE) of carbon-negative RNG per year. That RNG will be used to offset greenhouse gas emissions from vehicle fleets operated by the University of California, Anaheim Public Utilities, and regional fleets served by Southwest Gas. It will also create 30 temporary and 14 permanent, high-paying, full-time union jobs.

BAC Comments on CalRecycle SB 1383 Regulations

BAC submitted comments on CalRecycle’s October 2019 draft of regulations to implement the  organic waste diversion requirements of SB 1383.  CalRecycle expanded the list of eligible alternatives to landfilling to include electricity, heating, and vehicle production from diverted organic waste.  The draft regulations also include electricity generation from biomass conversion, but the October draft deleted pipeline biogas, which could exclude the use of biogas for cooking, commercial and industrial purposes.
